2 Cloud adoption in India
The cloud computing Infrastructure as a Service (IaaS) market is at a nascent stage both
globally and in India. Across industry segments, the Indian market has shown signicant
interest in the potential of IaaS services. Virtualization, often seen as the rst step in a
cloud strategy, has begun to be more widely implemented across Indian data centers.
Related markets such as Software as a Service (SaaS) is experiencing increased
adoption and this can be expected to contribute to a more rapid implementation of the
IaaS concept. However, there are signicant barriers to adoption, including the absence of
an IaaS ecosystem and the lack of awareness of available services on the part of
potential buyers.
This report is an attempt to reach out to chief information ofcers (CIOs) and analyze
their expectations from, and perceptions of, the Indian IaaS market and draw relevant
inferences for the entire IaaS ecosystem. It intends to dene areas that will benet

1. Executive summary
Cloud computing IaaS brings utility computing closer to reality. It has the potential to
change the way IT hardware is purchased, designed and used. With its promise of innite
scalability and a pay-as-you-go pricing model, the primary benet that cloud IaaS services
extends to the large enterprise is greater business effectiveness at lower IT costs. For the
small and medium business (SMB) segment, cloud IaaS services lower barriers to market
growth by lowering technology costs and upfront investments.
What are the primary drivers of cloud adoption in India likely to be?
On the demand side, improving high-speed connectivity, an emerging SMB segment
investing in IT infrastructure and increasing enterprise data center expenditure are
drivers that are expected to contribute to a growing cloud IaaS market. From the supply
perspective, a maturing traditional IT market and an extremely competitive third-party
data center market are likely to be primary drivers of cloud IaaS services.
Our survey targeted CIOs of enterprises belonging to both the SMB and large enterprises
segments. On the buyer side, despite the low visibility of IaaS vendor services in the
market, most CIOs surveyed are aware of, and have expressed interest in, the concept and
the potential benets of moving at least part of their applications to servers and storage
on the cloud. The following are among the key ndings from the survey:
Positive perceptions, awareness levels and expected timelines for adoption are•
indicative of a market that is ready to experiment with cloud IaaS services.
Effective communication from service providers at this stage should dispel some of the•
concerns that enterprises have around ecosystem maturity.
The SMB segment is more attuned to the benets and challenges of the cloud.•
Furthermore, the maturity of the ecosystem is less of a deterrent to the SMB segment.
This makes the SMB segment ideal to approach as an initial adopter of cloud IaaS
services.
Enterprises perceive data security and privacy as the biggest barrier to adoption.•
Third-party data service providers and traditional IT service providers are being viewed•
as the primary channels for enterprises to buy cloud services from. Such providersshould play a pivotal role in bringing the ecosystem together.

5Cloud adoption in India
Both enterprises and service providers are likely to benet from a consultative approach
and in-depth discussions with cloud IaaS service providers in the following areas:
The differentiating benets of cloud IaaS services•
Pricing structures, nancial models and return on investment (ROI) that a cloud•
adopter can expect from moving to the cloud
Guidelines and benchmarks to help enterprises select applications that are most•
suitable for adopting either the private or the public cloud models
Addressing security and data privacy issues satisfactorily•
Extending customer support to adopters of the technology•
For the purpose of this report, IaaS includes both computing/processing capacity and the
storage capacity available through remote virtual server infrastructure.
The cloud services ecosystem is evolving rapidly. Active participation from both service
providers and enterprises at this juncture will help create a more robust ecosystem and
shorter time to adoption. In this report, we evaluate the opportunities, advantages and
challenges for cloud computing infrastructure as a service adoption in India.

2. The Indian IaaS market
At present, the Indian market does not have a mature ecosystem that supports cloud
IaaS services. As such, the cloud IaaS market in India is yet to take off. A few players from
the service provider segment such as Tata Communications, Wipro and NetMagic have
announced services that are likely to evolve into more stable cloud offerings.
Tata Communications, for example, offers its customers an advanced virtualized
environment with exible arrangements to enhance capacity. On the consumer side, Airtel
is offering Net PCs, low-cost online computers with processing capability accessible over
the net. Infrastructure providers of the cloud such as VMWare, NetApp and IBM havecrystallized offerings for the private cloud, and have taken proactive steps in educating
the consumer on the benets of cloud IaaS services. Some of the challenges the market
currently faces include:
Ecosystem maturity•
Customer awareness of services•
Connectivity•
The market is seeing a concerted effort in the related Software as a Service (SaaS) space.
The SaaS market is increasingly gaining acceptance in the SMB segment, indicating a shift
in the thought process of CIOs and IT decision makers. A recent NASSCOM EmergeOut
session, held in August 2009, focused on SaaS and the cloud market. The IaaS market is
also likely to benet from the increasing maturity of these related markets.
2.1 Drivers for cloud IaaS services in the Indian market
While the market is currently at an embryonic stage, the presence of several positive
drivers lends to the promise of cloud IaaS services evolving into a fast-growth segment.
SMB segment: The size of the Indian SMB market exceeds that of any other country in
the Asia-Pacic region. India is also forecasted to achieve the highest SMB IT expenditure
growth rates, with more than 50% of the expenditure expected to be dedicated to
hardware. Even at its current stage of maturity, cloud IaaS is a viable proposition for most
enterprises in the SMB segment. Cloud IaaS services give SMBs access to technologies
they would otherwise not be able to afford. The low lead time of cloud IaaS to deploymentand scalability also negates technology barriers to growth. For vendors offering IaaS, the
Indian SMB market provides a unique opportunity to enter and grow this segment.
Low protability of third-party data center service providers: Third-party data centers
currently operate at extremely thin margins. This can be largely attributed to the product
mix, which leans toward basic co-location services rather than value-added, high-margin
services such as managed hosting. Cloud IaaS services offer service providers the
opportunity to leverage their existing IT investments to create a new line of value-added
services with more protable revenues.
ISP telecom operators: Moreover, in the Indian context, internet service providers
(ISPs) own and operate many of the larger data centers. Telecom ISPs have investedsubstantially in bandwidth creation, and currently, the market has excess bandwidth
capacity. Introducing cloud IaaS services to their current portfolio will help ISPs increase
bandwidth usage and increase customers’ switching costs.

Enterprise data center expenditure: With signicant power and electricity overheads,
enterprise data centers are a major drain on enterprise IT budgets in India.
Ernst & Young’s survey indicates that more than 80% of the enterprises surveyed are
considering initiatives to reduce the overall footprint of their data centers. The average size
of an enterprise data center in the Indian market is in the range of 1,000–1,500 sq. ft. The
cost structure of an average data center is illustrated below. As a result of under-utilization,
the overhead cost of under-utilized infrastructure tends to be a signicant cost driver.
Maturing traditional IT market: The growth projection for the domestic IT market is
between 2008 and 2013 is expected to be 15.8%, as against the average annual growth
of 25% recorded during between 2003 and 2008 (IDC estimates). With slower growth
and increasing competition in the traditional IT outsourcing services market, vendors are
seeking new business models to increase their revenue streams.

2.2 Barriers to adoption in the Indian market
Ecosystem maturity: While the cloud IaaS space has elicited interest from a number of
larger players across both system integrators (SI) and telecom ISP providers, there are
very few ‘true’ cloud offerings at present. This is a major deterrent for a potential cloud
IaaS customer.
Customer awareness: Most potential customers are knowledgeable about IaaS services.
However, they not aware of its overall impact and the return on investment (ROI) that
adopting such technologies can yield. They are also not aware of the specic services that
vendors in this space offer.
NetMagic is the rst vendor
to offer cloud infrastructure
services in India. As part
of its cloud-computing
portfolio, NetMagic offers
the following services:Cloud Serve is targeted at the•
SMB segment and provides
disposable servers thatare congured on demand
depending on business needs.
Cloud Net is a service model•
that provides the customer
with the capability to create
complete IT infrastructure,
including servers, rewalls,
load balancers and switches.
This service specically
addresses the opportunities
of hosting portals, disaster
recovery and the testing of
mid-sized internet companies
and traditional enterprises.
PrivateCloud is a dedicated•
hosted cloud infrastructure
service catering to large
individual enterprise
requirements.

8 Cloud adoption in India
Connectivity: Poor connectivity may prove to be a signicant barrier to adoption. Low
internet and PC penetration (less than1% in urban areas, 31 PCs per 1,000, according
to NASSCOM’s report, Perspective 2020) are discouraging. However, given the recent
regulatory progress in third-generation (3G) and fourth-generation (4G) technologies, the
expansion of private players, government initiatives and the declining cost of PCs, India is
likely to see considerable progress in broadband and internet connectivity over the next
two to four years.
While exact price structures are yet to evolve, vendors are looking to reduce prices by
at least 20–25%. Existing players can expect to see other international and local players
enter this space. As compared to the global market, India is yet to see the entry of cloud-
related, value-added software solutions related to billing, provisioning and management.
This could be a potential challenge for Indian service providers.

“Which of the following concepts of cloud computing are you highly familiar with?”
Familiarity with cloud-computing concepts
Gauging from the awareness indicated by 81% of the survey respondents, IaaS awareness
is certainly not expected to hinder cloud IaaS service adoption. A related question on
areas of adoption indicates that people are equally open to adopting cloud in storage and
processing capability.
Further, the survey indicates that awareness levels on SaaS are currently lower than that
of IaaS. The SaaS market in India has only just begun to enter a phase of realization. SaaS
vendors are pushing aggressively in the market for the adoption of their services. As this
market grows, a benecial spillover effect on the IaaS market can be expected.
The main drivers of growth
in the Indian cloud market
are the SMB segment, the
current low protability of
Indian data service providers
and the enterprise’s need to
reduce data center-related
costs. Ecosystem maturity
and customer awareness
of available services and
connectivity are the current
barriers to cloud adoption.

can target. Of the total respondents surveyed, 68% have a positive mindset toward cloud
computing, with 24% regarding it as a driver of the next wave of IT innovation and 44%
believing that it will mature in a few years.
Around 20% of the respondents were not aware of cloud-computing services in great
detail. This section represents a sizeable percentage that is likely to benet from customer
outreach programs, industry events and demonstrations educating them about the
concepts as well as the benets of cloud computing. A minority of 12% believes that cloud
IaaS services will not suit their business needs.

3. Perceived benets of implementing
cloud IaaS services
The potential benets of a well-designed and well-executed cloud-computing
infrastructure services strategy can be signicant. The relative importance of each benet
varies considerably with the size of the enterprise. Key benets include lower costs, an
on-demand self-service model, low entry barriers and the elasticity and scalability of
resources. This section summarizes the benets as perceived by potential adopters of the
cloud IaaS services in the Indian market.

13Cloud adoption in India
There is a distinct difference in the perceived benets of cloud by the SMB and enterprise
segments. The SMB segment considers cloud IaaS services for “true” cloud benets, while
the large enterprise perceives benets on the operational side that are generally derived
from an outsourcing model.
The SMB segment has cited high uptime as the top operational benet, while large•
enterprises regard lower risk of technology obsolescence as the most important
operational benet.
The SMB segment regards usage-based payments and low capital investments as•
extremely signicant business benets, while the large enterprise perceives the ability
to focus on core activities as the top business benet.
Cost does not seem to be a factor in driving the decision to adopt cloud IaaS services.Surprisingly, both the SMB and large enterprise segments have given lower priority to
other typical cloud benets such as the ability to innovate and faster deployment. This
may be indicative of an awareness gap of the differentiated benets that cloud IaaS
services are capable of delivering.
3.2 Moving to an OPEX model
At 58%, the majority of the respondents favor a model that facilitates the shift of
expenditures from a capex to an OPEX model.
Of the total respondents surveyed, 38% are neutral to the shift.•
Only 4% of the respondents do not see any benet in the shift.•

4. Perceived challenges to cloud IaaS
services adoption
Implementing cloud computing will not be without challenges. Ernst & Young’s market
survey indicates that an overwhelming 72% of the respondents cite potential data privacy
and security issues as extremely signicant concerns. The other area of concern is around
vendor maturity and the capability to provide cloud services. Among the challenges
generally associated with a shift to cloud IaaS services are:
Data security and privacy•
Legal and regulatory compliance•
Control and responsiveness•
Lack of benchmarking or leading practice experience•
Ambiguity over how best to quantify, track and communicate the benets of•
cloud computing
Threat of potential over reliance on a single-source IT provider•
Lack of interoperability•
Resistance from datacenter IT personnel•
The following section summarizes some of the key challenges the Indian market perceives.

Data security and privacy is a major concern for enterprises considering implementing
cloud IaaS services. Cloud IaaS is a distributed computing model with inherent ambiguity
around where the data resides. This distributed model leads to a perception of higher riskand security challenges. A cloud service provider can mitigate these risks by establishing
an effective security and controls framework (appendix D) in the following areas:
Identity and risk management•
Compliance and audit•

17Cloud adoption in India
Vendor lock-in is perceived as a signicant challenge to the adoption of cloud computing.
Vendors can currently mitigate this concern by making their services more transparent
so that customers can understand how their resources are being managed. In the long
term, as the ecosystem matures and the industry adopts open standards to facilitateinteroperability, this concern will likely be mitigated. Efforts need to be made to develop
forums such as the Open Cloud Alliance to enable the development of more transparent
and interoperable solutions.
Enterprises are also unsure of the cost savings that cloud computing can help them
achieve. Vendors need to develop comprehensive nancial models detailing the
comparison of in-house infrastructure with cloud IaaS to help rms estimate the ROI.
Usage-based pricing models with monthly or hourly billings can be used to compare costs
with the current datacenter costs and estimate the ROI.

18 Cloud adoption in India
The shortage of mature service providers is the single overwhelming environment-related
challenge that enterprises perceive. Vendors need to develop go-to-market strategies to
develop customer relationships and retention strategies. Collaboration among all channel
partners is required to build a compelling case and visibility for cloud IaaS services.
Vendors need to create effective strategies on the value proposition and features (“what
to sell”) for different market segments (“whom to sell”) and a denitive sales and channel
partner strategy (“how to sell”).
Cloud service providers should invest in developing cloud labs that enable customers to
use cloud IaaS services on an experimental basis. This is also expected to assist customers
in assessing challenges that could arise from integrating enterprise data centers with
infrastructure on the cloud. Cloud-computing adoption case studies of customers
worldwide should be made available to enterprises to help them clearly understand
the areas where cloud IaaS services benets can be leveraged. Interestingly, the SMB

segment does not perceive environmental challenges to be as critical a barrier to adoption
as compared to the large enterprises. The lack of mature service providers, guidance or

the SMB segment as potential early adopters of cloud computing.
The most signicant
challenges enterprises
perceive in adopting cloud
IaaS services include
data privacy and security,

and ecosystem maturity.
Signicantly, the SMB
segment does not rate
ecosystem maturity as a
major challenge.

5. Expectation from vendors
This section summarizes the survey’s key findings regarding the enterprise expectation of
vendors. It covers areas unique to the cloud IaaS services environment such as the pricing
model, service channels, acceptable security and controls framework and key vendor
assessment criteria.

Others
The essence of the cloud IaaS model is a pay-as-you-go financial model. The high percentage
of respondents indicating their preference for annual contract-based pricing indicates lack
of clarity on the cloud’s financial model. Further analysis indicates that the majority of therespondents opting for an annual contract-based model are the large enterprises, while the
majority of the SMB segment prefers the resource-based usage model.
At this stage, a single pricing model is unlikely to satisfy all potential customers in the
market. Vendors need to have pricing structures that are easily understood, transparent
and offer substantial benefits in terms of cost savings. Options for alternative pricing
models can be as follows:
A true pay-as-you-use model based on the use of resources such as per hour usage or•
CPU cycles consumed will be attractive to the SMB segment.
More flexible models integrating the features of usage- and contract-based pricing can be•
developed, where server instances can be charged on a daily or monthly basis instead of hourly.
Reserved instances with discounts on hourly rates can be more cost-effective for larger•
enterprises with visibility on demand. Reserved instances are likely to help large enterprises
better estimate and plan their cloud IaaS needs.

20 Cloud adoption in India
The stated preference of enterprises to buy cloud IaaS services from IT service providers
or data center service providers could mean that the cloud computing idea becomes
central to these service providers’ portfolios. Equipment vendors should recognize and
respond to this possibility.
For data center providers, cloud IaaS services may prove to be a more protable sourceof revenue as compared to their existing service/product mix. IT service providers looking
to leverage the cloud IaaS opportunity should form alliances with third-party data center
service providers or invest in building their own infrastructure.
Data center service providers and IT system integrators also need to play a pivotal role in
bringing the ecosystem together to demonstrate commitment to security, service-level
agreement (SLA) adherence and complete support at every layer of the cloud
service model.

Data security and privacy again shines through as the top differentiating factor for the
enterprise. Providers should refer to Appendix D for an initial guidance on security areas
to be considered for cloud adoption.
While vendor lock-in and lack of guidance are perceived to be challenges to cloud-
computing adoption, interoperability and vendor support network are not rated very high
on the criteria list of vendor assessment. This indicates that both these factors can be
expected to be barriers to adoption and associated with the environment rather than as
differentiating factors between vendors. With cloud IaaS services being a new business
and operational model, a high degree of customer interaction during the sales cycle and a
strong support framework will assist customers in adopting the technology seamlessly.

6. Recommendations
As the market evolves, economies of scale provided by third-party organizations through
cloud computing IaaS can create a viable environment for enterprises to reduce costs and
better align limited IT resources with key business goals and initiatives. In a market that is
ready to experiment with cloud IaaS services, providers need to begin crystallizing their
cloud offerings, while cloud adopters should begin to engage with providers to include
cloud IaaS services in their overall IT strategy.
6.1 Recommendations for service providers
1. Develop a cloud IaaS strategy: The market is ready to experiment with cloud IaaS.
Cloud providers should incorporate a cloud IaaS strategy in their overall portfolio and
initiate communication with potential buyers on the drivers and total value proposition
of cloud IaaS services to enterprises. Storage as a Service can serve as an initial service
offering, since it is an easier area for enterprises to experiment and integrate with. There
is an expressed need-awareness gap on the storage offering in the market, with 55%
indicating their readiness to adopt the technology and only 33% indicating awareness of
the service.
2. Reach out to the SMB segment: Providers should target the SMB segment for initial
adoption. The SMB segment is more attuned to cloud benets and challenges, thus
making the SMB segment the ideal early adopter of the technology.
3. Develop go-to-market strategy focusing on future roadmap for cloud IaaS: Providers’
go-to-market strategies need to be aggressive in communicating the cloud IaaS services
currently on offer as well as the future roadmap of these services.
4. Set up test labs: To allay apprehensions surrounding the actual applicability of cloud
IaaS services, vendors should set up test areas, which customers can access on an
experimental basis. This will allow enterprises to experience the technology before full-
scale adoption.
5. Communicate with buyers on the perception of cloud benets and challenges: The
perception of these benets and challenges need to be factored into communicationstrategies, service offerings and SLA structures.
6. Develop pricing models and ROI expectations: Enterprises are expected to benet
from detailed nancial models benchmarking in-house data center costs with the
investment and running costs associated with the cloud IaaS model, using different pricing
models to help estimate the ROI.
8/3/2019 Cloud Computing Adoption in India

23Cloud adoption in India
7. Establish collaborative engagements with the enterprise: The cloud IaaS space is
evolving. As such, it is necessary for vendors to take a collaborative approach to engaging
with enterprises. Providers should focus on the following areas:
Differentiating the benets of cloud IaaS services•
Discussions with potential buyers on the pricing structure, nancial model and ROI that•
a cloud adopter can expect from moving to the cloud
Guidelines and benchmarks to help enterprises select applications that are most•
suitable for adoption in either the private or the public cloud model protably
Security-related aspects•
8. Building the ecosystem: Data center service providers and IT system integrators
should also play a pivotal role in bringing the ecosystem together and demonstrating the
commitment to security, SLA adherence and complete support at every layer of the cloud
service model.
9. Building competitive advantage: Some of the ways in which cloud service providers
can build their competitive advantage in this space include:
Providing consulting and integration support to customers•
Providing excellent customer support options•
Building the SLA framework in collaboration with the enterprise•
Security and data privacy concerns should be met as a primary hygiene check•
10. Addressing security concerns: Cloud computing IaaS services constitute a distributed
computing model with inherent difculties in locating where the data is stored. This leads
to a unique set of security challenges and concerns.
6.2 Recommendations for enterprises
Enterprise IT decision makers need to continue monitoring the market in the short
term for provider strategies around cloud IaaS services. Enterprises at the forefront of
technology adoption should start interacting with service providers to understand current
offerings. Although the ecosystem does not appear to be mature enough to extend
support to a complete cloud IaaS services portfolio, the economic crisis could well serve
as an impetus to both providers and enterprises to opt for the cloud. With providersbeginning to invest in infrastructure, the economics and feasibility of cloud services are
likely to evolve rapidly.

Companies considering cloud computing need to consider the broad range of business
factors and effects that may arise from such an initiative. Among the cloud computing-
related areas companies should consider are:
Privacy•
Enterprise architecture•
Information security•
Application controls and security•
IT effectiveness/transformation•
The following questions are critical for business leaders to consider when planning atransition to cloud computing:
How can my data center be better equipped to function with part of its infrastructure•
on the cloud?
What specic areas are most appropriate for cloud computing?•
What services are third-party vendors providing?•
What are the most signicant data privacy and security issues that we will likely face?•
What are the cloud provider’s key risks and performance indicators, and how will this•
impact be monitored and measured from an enterprise perspective?
How can I deploy IaaS in a way that makes it relatively easy to switch providers, if•
needed?
What are we trying to achieve through cloud computing? What ROI can we expect?•
What technology needs will be required with cloud computing?•
How do I assess the actual infrastructure that will be needed to support my•
applications? How do I benchmark application performance in the provider
environment?
How does resource pooling and allocation occur within the cloud providers’•
infrastructure setup?
Based on the approach, application performance and expected usage patterns, what is•
the best pricing strategy?
How can existing resources, both machines and people, be reallocated for maximum•
impact?What are the broader cultural and operational implications of this approach?•
Cloud IaaS service providers
should look at building
out a complete cloud
IaaS service portfolio and
begin communicating with
potential buyers. Enterprise
IT decision makers should
continue to monitor the
market in the short term
for provider strategies
around cloud IaaS services
and actively participate in
creating a robust ecosystem.

Appendix A: models of
cloud computing
There are three typical models through which cloud-computing services are offered:
Software as a Service (SaaS)• : Software is offered as an on-demand service, thereby
reducing the need for the customer to install, upgrade and maintain applications.
Salesforce.com is one of the rst enterprise applications to be offered as SaaS.
Platform as a Service (PaaS)• : The development environment is provided as aservice that encapsulates a layer of software integrating the operating system (OS),
middleware and application software. Customers develop applications with the help of
vendor-provided application programming interfaces (APIs) on platforms enabled with
automated management and scalability. Commercial examples of PaaS include Google
Apps Engine and Microsoft Windows Azure.
Infrastructure as a Service (IaaS)• : Processing, storage and bandwidth are offered
on demand with metered billing. A consumer can store data and run an OS, software
applications and web or database servers on the rented hardware. Some major
commercial examples of IaaS include Amazon, Rackspace and Savvis.
There are three main cloud
service models: SaaS, PaaS
and IaaS. IaaS provides the
capability to execute rent
processing and storage
over the internet. It is, in
many senses, the most
commoditized version of
cloud services.

Drivers of cloud IaaS services in the global market
Among the major factors contributing to the growth of the IaaS market is a maturing
ecosystem. Amazon.com was one of the rst to offer cloud IaaS services on a commercial
scale, and has successfully established market dominance in this space. Amazon currently
has more than 440,000 developers registered with Amazon EC2 and storage services.
IBM is also betting heavily on becoming one of the few true utility providers of technology.
The company has strategically located IBM cloud labs in both major and emerging
markets. IBM is now looking to leverage these cloud labs to address the specic needs of
customers experimenting with transitioning IT requirements to the cloud model.

Within a short span of time, other top players such as Google and Microsoft started
offering cloud products. A number of niche players are also challenging Amazon’s market-
leading position, including service providers such as Savvis, Verizon, Box.net, GoGrid and
Terramark. Support and commitment from large players have also led to a concerted
effort to educate customers through conferences, seminars and publicity. Industry
forums such as the Open Cloud Alliance are focusing on resolving some of the barriers to
cloud adoption, including inter-operability and security. An extremely robust developer
community that has taken to developing and deploying applications on the cloud has also
helped popularize cloud IaaS services.

Case study: Vendor solutions
Source: Amazon Web Services (AWS) website
Amazon: The Amazon AWS cloud-computing platform can host business applications
on the cloud with resizable compute capacity. The Amazon Elastic compute is a web
service that provides a virtual development platform. AWS has recently introduceda limited beta version of its Virtual Private Cloud (VPC). The VPC is intended to be a
hybrid solution, extending to enterprises the capability to connect their existing IT
infrastructure to an isolated set of resources at the AWS data center through a virtual
private network connection.
Instances are charged on hourly usage basis, with charges increasing in tandem with
compute capacity. There is also a provision to reserve the instance by making a low
one-time payment with a signicant discount for its hourly usage rate. Limited inbuilt
memory for a server instance is free. More volume of data can be stored in Amazon
Storage Services (S3), where it is billed at storage rates. Data transfer is billed based on
data transferred in and out of Amazon EC2. Elastic IP and elastic load balancing are also
charged separately.
IaaS has steadily gainedground in the past few
years. Support and
commitment from a number
of large players in the
market and well-publicized
implementation of the
cloud have contributed
to its success.

Appendix C: IaaS and the enterprise
IaaS is an operational model in which physical IT resources are delivered as abstracted IT
services, both on demand and at scale. IaaS mainly refers to processing and storage capacity
available from anywhere, through any connected device. Infrastructure resides in massively
scalable provider data centers, where processing capacity and storage can be dynamically
provisioned and shared to achieve signicant economies of scale. The end user accesses the
infrastructure over the internet through a user-centric interface that makes the cloud IaaS
transparent.
On the buyer side, adding cloud IaaS leads to reduced capital spending on hardware and a
progressive shift from a capital to an operational model of IT expenditure. The degree to which
an enterprise implements cloud IaaS services can be directly related to the company’s growth
stage. A start-up company is more likely to use cloud infrastructure for most of its IT needs, as
this is expected to drastically reduce entry barriers. Larger enterprises are likely to use public
clouds to meet stretch capacity needs, while continuing to use private clouds and existing
enterprise data centers for heavier applications that require more uniform resource usage.
Storage as a service: The provider rents out storage hardware on a cost-per-gigabyte-data-
stored model. Storage as a Service provides a cost-effective method with which to meet the
enterprise’s data-storage needs. Cloud storage offers an alternative solution for particular
kinds of unstructured le data, which require batch processing and have low security
requirements or large datasets such as rich media les, image les and records, streaming
media and secondary/tertiary web accessible storage for data.

Backup and archival are among the traditional uses of cloud storage. However, as it
evolves, cloud storage is expected to also power the development of a new breed of
applications that leverages service-oriented architecture (SOA), web services, APIs and
their advanced services.
An example of such an application is a content delivery network (CDN), which is ideal
for cloud hosting and the distribution of popular les accessed frequently. Regular
cloud storage networks to access such les are not optimal, as they support lower data
transfer speed. CDN is a viable alternative for hosting frequently accessed website
components and distributing downloadable software and its updates, media audio and
video les. Integration with cloud storage is provided through APIs, which support multiple
programming languages.
Computing as a Service (CaaS) provides the capability to spin up virtual machines
and load them with pre-congured or customized images of OS, web and database
servers, thus creating a complete virtual environment for application development and
deployment. Processing capability is provided as server instances congured with OS and
software images acting as units of deployment. The virtualized server instance may be of
varying sizes, with different memory, instance storage and virtual core congurations.
CaaS is conducive to a variety of processing needs, and has so far been used primarily for
the following:
Building a virtual test and development environment on the cloud, replicating•
production environments
Applications with unpredictable capacity requirements such as those directed toward•
marketing campaigns
Data mining applications needing high-powered processing over unstructured data•
Bandwidth that is used to access cloud IaaS services is billed for bandwidth usage on a•
per-GB-data inbound and outbound transfer.
Case study: Customer adoption of IaaS
July Systems• : July Systems is a leading mobile media company offering feature-rich
mobile solutions for live events, updates and advertising on its Mi™ Channel. July
Systems Live Center on Mi™ faces extremely dynamic requirements due to supportextended for multiple devices, dynamic content and the personalization of delivered
content. The platform also faces steep hikes during sports events and live news.
July Systems uses Amazon’s cloud computing services to cost-effectively scale its
business.
British Telecom• : British Telecom uses AppLogic to deliver market-leading, on-demand
telecom services using only a web browser and basic IT skills. 3Tera offers AppLogic
utility computing services through a grid platform that converts commodity servers
into scalable grids, on which users can visually operate, deploy and scale transactional
web applications without any code modications.
Eli Lilly• : To invent a breakthrough drug, Eli Lilly needed 25 servers to crunch large
volumes of data. Rather than taking months to become functional, Eli Lilly took
the alternate cloud route. Eli Lilly created an account on AWS and had 25 servers
operating almost instantaneously. Consequently, transactions were completed within
a day at a total cost of USD89.

A key aspect of the overall IaaS experience to the end user is the provisioning and
management layer that abstracts the hardware. Some of the key functionalities delivered
to the user through this layer include:
Billing•
End-user provisioning and scale up capability•
End-user monitoring and management•
User access and user management interface•
Wrapper interfaces such as software backup solutions•
Animoto• : Animoto is a good example of leveraging cloud for instant availability
and virtually limitless scope. Animoto’s Facebook application creates videos for
consumers and applications. The application is complex, with each subsystemrequiring multiple servers. Animoto ramped up from 25,000 to 250,000 users
in three days with the help of AWS, thereby provisioning around 4,000 servers
simultaneously.
CyberGamer• : Online gaming company CyberGamer has tapped the Rackspace
Cloud to support its growing number of subscribers. CyberGamer has increased its
membership from 1,000 users six months after its launch, to 21,000 by the end of
the second year. The requirements of a gaming company are dynamic because of the
uneven trafc ow and higher computing power needed to process queries round
the clock. On implementing virtualization, CyberGamer found that during peak times,
it would still hit a threshold that prevented new members from viewing the website
content. Subsequently, the company transferred its IT resources to the Rackspace
cloud with virtually no downtime and, as a result, experienced a 137% increase intrafc within the rst month. This was indicative of the amount of trafc the company
was losing previously on account of overloading.

Appendix D: addressing
security concerns
Cloud computing IaaS is a distributed computing model with inherent difculties in
locating where the data is stored. This leads to a unique set of security challenges and
concerns. Data security and privacy is also rated as the top concern of enterprises moving
to cloud technology. Listed below are some of these associated concerns as well as
suggested guidelines to resolve the concerns:
Issue Suggested guidance
Identity and access management
Identity and access management are very important for thestrategic use of dynamic cloud computing resources.
Providers’ authentication systems should either meet or exceed•enterprise standards.Enterprises should be encouraged to adopt single-sign on for•applications to simplify identity and access management.When resources move to cloud, authorization should be•provided at business-line levels, with policies regulating theprovision and release of resources.Encryption and key management policies should be•
implemented for secure access.Compliance and audit
Data location abstraction and multiple copies of data can provetroublesome with respect to compliance. It may be difcult to
audit the data in the cloud, because isolating the scope in a cloudenvironment is challenging.
Metrics for formalizing the audit should be developed.•Due diligence of the suitability of existing audit standards to the•cloud environment should be conducted.Cloud providers should try to acquire certications such as•SAS70.SLA and security-level objectives should be redened to include•data audit.
Application-level security
Porting an application on the cloud has implications such aswhat the security levels are and who controls them. The vendorproviding virtual machine images needs security levels similar to
those of in-house applications.
Vendors should provide the enterprise with capabilities to•create customized virtual machine images.Inter-application communication security should be ensured in•
a distributed cloud environment.Additional security and masking sensitive enterprise•information are needed.Application security must be represented as a clearly•articulated set of actions and guarantees within the SLA.
The growth of cloud computing is expected to increase the type•and occurrence of incidents, such as malware infection, databreach, Man-In-The-Middle discovery, session hijacking anduser impersonation. Application-level rewalls and vulnerability
detection need to be put in place.
Security and data privacy guidance principles

33Cloud adoption in India
Issue Suggested guidance
Data backup and disaster recovery
Data backup and disaster recovery are among the most desiredsecurity and control framework controls.
Vendors need to ensure the redundancy and backup of all•hosted data through replication and storage across multiplezones.Business continuity plan with round-the-clock failover•protection are required.The SLA should include terms on data backup and disaster•recovery.
Legal
Some of the legal risks are similar to those faced in any•outsourcing industry, with the enterprise being heldresponsible for any acts of its subcontractors.Some customer contracts prohibit trans-border data ow.•The adoption of industry standards for security and•regulations are mandatory for some types of data.Enterprises may need to know the physical location of their•data, which can be dynamic and prone to change.Data residing in the cloud may not be easily accessible for•electronic discovery in case of litigation.
Enterprise and vendors need to perform due diligence and•evaluate their own practices, needs and restrictions to identifythe legal barriers and compliance requirements associated witha proposed cloud-computing transaction.Cloud vendors need to collaborate with the enterprise to dene•the key components of the contractual arrangement.The vendor needs to provide business continuity and disaster•recovery to prevent outages.The contract should be periodically monitored and reviewed.•In case of any change in the vendor’s business model or thecompliance laws, the contract should be updated accordingly.The legal implications of whether the third-party vendor or the•enterprise is held responsible in case of a data breach should beexamined.
The ownership and control of the data in the cloud should be•given to the enterprise so that it controls the condentiality,
security or privacy of its databases, or if it wishes to control theentity that has access to its data.

Appendix E: customizing the cloud
Like all good things, cloud IaaS services, too, come in many varieties. The nature of the
application and the level of control required determine the most suitable deployment and
connectivity model. Cloud services can be customized to include the following parameters:
Level of investment the enterprise is willing to make for the transition•
Core vs. non-core applications•
Expected SLAs and vendor commitment to application uptime•
Security•
Data privacy•
Degree of control the enterprise wants over its infrastructure•
Differences in cloud models arise from the deployment method and the way in which a
customer chooses to access cloud IaaS services.
Deployment models
Cloud services are primarily deployed and managed in three modes: public, private and
hybrid. The deployment models differ on two important factors:

35Cloud adoption in India
Public clouds: Third-party service providers offer public clouds. They are usually multi-
tenant (shared) operating environments with all the benets of elasticity, but the third-
party vendor controls the management of the resource and security.
Private clouds: An organization or its designated service provider supplies private cloud
services with dedicated rewalls and operating environments. The organization controls
the management and security of the cloud IaaS.
The challenges to private cloud adoption are primarily around high initial capital
investments and less scalability due to the limited availability of resources as compared to
a public cloud.
Hybrid clouds: Hybrid clouds are a combination of public and private cloud offerings. They
enable the organization to retain direct local control over critical data while continuing to
offer the advantage of the economies of scale available through a public cloud for services
that are not critical. For example, a single application such as email systems can span
through both realms by linking an on-premise email infrastructure with a public cloud
service for continuity. This can help organizations reduce the total cost of IT operations
while still meeting their security and regulatory requirements.

Accessing the cloud
A number of network options such as public internet, private dedicated lines or hybrid solutions (VPN) should be evaluated to selectthe best-access option for the service. Performance and cost are among the parameters that are used to judge the network. Indian
ISPs currently provide high-speed broadband ranging from 100Mbps for public internet to Ethernet-based WAN 10Gig-Ethernet of
dedicated internet access for enterprise customers. Network options such as VPN provide enterprises with the same capability that
private leased lines traditionally deliver, but with cost savings enabled through the use of shared networks. Virtual private cloud is
built on the concepts of VPN, providing enterprise-level security to resources deployed on the vendor’s public cloud platform.

Appendix F: benets of implementing
cloud IaaS services
The potential benets of a well-designed and well-executed cloud-computing
infrastructure services strategy can be signicant. The relative importance of each benet
varies considerably with the size of the enterprise. Key benets include:
Lower costs: The combination of reduced capex with a pay-as-you-use model effectively
changes the prole of IT expenses from capex to OPEX.
Data centers currently account for around 30–45% of enterprise IT costs. Data center
capacity is usually provisioned for close to peak-capacity utilization, while actual
utilization varies between 15–45%. Apart from the direct costs of setting up the data
center, the actual running costs almost double the actual cost on a per server basis. This
is primarily due to high overheads arising from power and cooling requirements. The
cloud model eliminates the overheads with the pay-as-you-use model and the dynamic
allocation of resources based on actual demand. Public clouds are also most likely to have
infrastructure with higher processing capacity, which translates to lesser time to run
compute-intensive applications.

On-demand self-service model: The on-demand self-service model of cloud IaaS services
essentially implies that a consumer can unilaterally become self-sufcient in provisioning
computing capabilities such as server time and network storage without requiring human
interaction. This ease of deployment is a major advantage to a line of business that faces
roadblocks from the IT department in taking innovations to market. Access to resources
in traditional IT involves hierarchical channels, which results in lower speed and ease
of deployment as compared to the cloud, where hardware capabilities are offered as
transparent, on-demand self services. The end impact is IT infrastructure that is extremely
responsive to business and an increased pace of innovation.
Low entry barriers: Cloud computing reduces the barriers to entry because infrastructure
is rented rather than purchased. With minimum upfront capital investment, even rms
with lower IT hardware budgets can leverage the scale and capability of the cloud provider
to build applications on the latest technologies. To the SMB enterprise, cloud IaaS services
extend the benet of minimizing start-up costs by making available much of the required
computing capacity easily. For the SMB segment, this becomes the primary driver for the
adoption of cloud IaaS services.
Elasticity and scalability of resources: The capabilities available for rent appear to be
innite and can be purchased in any quantity at any time — an application never “goes
down” due to the inability of infrastructure to scale up to demand. Computing resources
can be rapidly and elastically provisioned to quickly scale up and rapidly released to swiftly
scale down. The capability to provide and use multiple systems simultaneously for high-
process computing needs also has the potential to signicantly reduce overall time tocomplete operations.

Appendix G: challenges in shifting to
a cloud IaaS model
Data security and privacy is the most often cited area of concern around the
implementation of cloud computing. Security issues arise mainly due to the dependence
on an external service provider and sending potentially sensitive data out of the enterprise
data center. Some of the anticipated challenges are generic to any outsourcing scenario,
while others are unique to the cloud services provider. Overall, the challenges that
enterprises anticipate when transitioning to cloud include:
Data security and privacy issues• : As compared to a more traditional IT outsourcing
arrangement, cloud-computing clients do not have dedicated servers. This raises
concerns around where exactly client data exists and under whose jurisdiction it resides
at any single given point.
Legal and regulatory compliance• : Many companies have to follow a number of
regulatory compliance laws. Some rms have regulations, which do not allow their
data to cross national boundaries. The data-handling regulations require the ability
to track changes and follow audit trails. In cloud, there is a perceived compliance and
operational risk of dependence on the vendor. A well-developed compliance and risk
mitigation strategy by the service provider will help mitigate this risk.
Control and responsiveness• : With in-house IT functions and employees reportingdirectly to in-house executives, there is little question about who should be doing what
and when. However, when employees and servers are separated, the provider’s and
executive’s priorities may not be aligned.
Lack of benchmarking or leading practice experience• : Because the use of off-site
computing capability is relatively new, there is insufcient experience from which to
draw guidance for companies looking to build an effective cloud computing strategy.
For example, there is some uncertainty on how to plan cloud capacity to meet the
existing performance requirements of current applications, or how to factor in current
architecture into cloud servers.
Ambiguity over how best to quantify, track and communicate the benets of•
cloud computing
Threat of potential over reliance on a single-source IT provider• : The relativelyeasy turnkey nature of cloud computing and its subsequent attraction of cost
reduction may promote a company’s gradual overdependence on a particular
third-party service provider.
Lack of interoperability• : There are no prevalent standards for vendor interoperability.
This gives rise to fears of vendor lock-in among the enterprise.
Resistance from datacenter IT personnel• : Current datacenter operations personnel
may resist the adoption of cloud computing at present, owing to the fear of losing their
jobs. The adoption of any new technology requires a change in mindset and culture of
the organization.

Appendix H: cloud enabling technologies: virtualization
Virtualization is the technology that makes cloud computing a reality. Shared resources are
made available on demand through memory, storage and network abstraction enabled by
virtualization, thereby allowing multiple operating systems to run on a single physical system.
The virtualization of servers and storage helps improve hardware utilization dramatically,
from 15–20% to 75–80%. An added advantage is reduced expenditure on cooling and power.
