Implementation of Private Cloud

CHAPTER 1

INTRODUCTION

Imagine yourself in the world where the users of the computer of todays internet world dont have to run,

install or store their application or data on their own computers, imagine the world where every piece of your

information or data would reside on the Cloud (Internet).

As a metaphor for the Internet, "the cloud" is a familiar clich, but when combined with "computing"

the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as anupdated version of utility computing: basically virtual servers available over the Internet. Others go very

broad, arguing anything you consume outside the firewall is "in the cloud", including conventional

outsourcing.

Cloud computing comes into focus only when you think about what we always need: a way to increase

capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or

licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in

real time over the Internet, extends ICT's existing capabilities.

Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew

of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style

infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such a

Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud

computing aggregators and integrators are already emerging.

CHAPTER 2

CLOUD COMPUTING - THE CONCEPT

Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). I

is a style of computing in which dynamically scalable and often virtualized resources are provided as a service

over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure

"in the cloud" that supports them.

The conceptIncorporates Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as

a Service (SaaS) as well as Web 2.0 and other recent technology trends which have the common theme of

reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include

Salesforce.com and Google Apps, which provide common business applications online that are accessed from

a web browser, while the software and data are stored on the servers.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer

network diagrams, and is an abstraction for the complex infrastructure it conceals.

2.1 Comparison:

Cloud computing is often confused with grid computing ("a form of distributed computing whereby a 'super

and virtual computer' is composed of a cluster of networked, loosely-coupled computers, acting in concert to

perform very large tasks"), utility computing (the "packaging of computing resources, such as computation

and storage, as a metered service similar to a traditional public utility such as electricity") and autonomic

computing ("computer systems capable of self-management").

Indeed many cloud computing deployments as of 2009 depend on grids, have autonomic characteristics and

bill like utilities but cloud computing can be seen as a natural next step from the grid-utility model. Some

successful cloud architectures have little or no centralized infrastructure or billing systems whatsoever,

including peer-to-peer networks like Bit Torrent and Skype.

2.2 Implementation:

The majority of cloud computing infrastructure as of 2009 consists of reliable services delivered through data

centers and built on servers with different levels of virtualization technologies. The services are accessible

anywhere that has access to networking infrastructure. The Cloudappears as a single point of access for all the

computing needs of consumers. Commercial offerings need to meet the quality of service requirements o

customers and typically offer service level agreements. Open standards are critical to the growth of cloud

computing and open source software has provided the foundation for many cloud computing implementations.

2.3 Characteristics:

As customers generally do not own the infrastructure, they merely access or rent, they can avoid capitaexpenditure and consume resources as a service, paying instead for what they use. Many cloud-computing

offerings have adopted the utility computing model, which is analogous to how traditional utilities like

electricity are consumed, while others are billed on a subscription basis. Sharing "perishable and intangible"

computing power among multiple tenants can improve utilization rates, as servers are not left idle, which can

reduce costs significantly while increasing the speed of application development. A side effect of this

approach is that "computer capacity rises dramatically" as customers do not have to engineer for peak loads

Adoption has been enabled by "increased high-speed bandwidth" which makes it possible to receive the same

response times from centralized infrastructure at other sites.

2.4 Economics:

Cloud computing users can avoid capital expenditure (CapEx) on hardware, software and services, rathe

paying a provider only for what they use. Consumption is billed on a utility (e.g. resources consumed, like

electricity) or subscription (e.g. time based, like a newspaper) basis with little or no upfront cost. Other

benefits of this time sharing style approach are low barriers to entry, shared infrastructure and costs, low

management overhead and immediate access to a broad range of applications. Users can generally terminate

the contract at any time (thereby avoiding return on investment risk and uncertainty) and the services are often

covered by service level agreements with financial penalties.




According to Nicholas Carr the strategic importance of information technology is diminishing as it becomes

standardized and cheaper. He argues that the cloud computing paradigm shift is similar to the displacement of

electricity generators by electricity grids early in the 20th century.

2.5 Companies:

Providers including Amazon, Microsoft, Google, Sun and Yahoo exemplify the use of cloud computing. It i

being adopted by individual users through large enterprises including General Electric, L'Oral, and Procter &

Gamble.




CHAPTER 3

HISTORY

The Cloud is a term with a long history in telephony, which has in the past decade, been adopted as a

metaphor for internet based services, with a common depiction in network diagrams as a cloud outline.

The underlying concept dates back to 1960 when John McCarthy opined that "computation may someday be

organized as a public utility"; indeed it shares characteristics with service bureaus which date back to the

1960s. The term cloud had already come into commercial use in the early 1990s to refer to large ATM

networks. By the turn of the 21st century, the term "cloud computing" had started to appear, although most of

the focus at this time was on Software as a service (SaaS).

In 1999, Salesforce.com was established by Marc Benioff, Parker Harris, and his fellows. They applied many

technologies of consumer web sites like Google and Yahoo! to business applications. They also provided the

concept of "On demand" and "SaaS" with their real business and successful customers. The key for SaaS is

being customizable by customer alone or with a small amount of help. Flexibility and speed for application

development have been drastically welcomed and accepted by business users.

IBM extended these concepts in 2001, as detailed in the Autonomic Computing Manifesto -- which described

advanced automation techniques such as self-monitoring, self-healing, self-configuring, and self-optimizing in

the management of complex IT systems with heterogeneous storage, servers, applications, networks, security

mechanisms, and other system elements that can be virtualized across an enterprise.

Amazon.com played a key role in the development of cloud computing by modernizing their data centers after

the dot-com bubble and, having found that the new cloud architecture resulted in significant interna

efficiency improvements, providing access to their systems by way of Amazon Web Services in 2005 on a

utility computing basis.

2007 saw increased activity, with Google, IBM, and a number of universities embarking on a large scale

cloud computing research project, around the time the term started gaining popularity in the mainstream press

It was a hot topic by mid-2008 and numerous cloud computing events had been scheduled.

In August 2008, Gartner Research observed that "organizations are switching from company-owned hardware

and software assets to per-use service-based models" and that the "projected shift to cloud computing wil

result in dramatic growth in IT products in some areas and in significant reductions in other areas."




CHAPTER 4

POLITICAL ISSUES

The Cloudspans many borders and "may be the ultimate form of globalization." As such it becomes subject to

complex geopolitical issues: providers must satisfy myriad regulatory environments in order to deliver service

to a global market. This dates back to the early days of the Internet, where libertarian thinkers felt tha

"cyberspace was a distinct place calling for laws and legal institutions of its own"; author Neal Stephenson

envisaged this as a tiny island data haven called Kinakuta in his classic science-fiction novel Cryptonomicon.

Despite efforts (such as US-EU Safe Harbor) to harmonize the legal environment, as of 2009 providers such

as Amazon Web Services cater to the major markets (typically the United States and the European Union) by

deploying local infrastructure and allowing customers to select "availability zones." Nonetheless, there are

still concerns about security and privacy from individual through governmental level, e.g., the USA

PATRIOT Act and use of national security letters and the Electronic Communication Privacy Act's Stored

Communications Act.




CHAPTER 5

LEGAL ISSUE

In March 2007, Dell applied to trademark the term "cloud computing" (U.S. Trademark 77,139,082) in the

United States. The "Notice of Allowance" it received in July 2008 was canceled on August 6, resulting in a

formal rejection of the trademark application less than a week later.

On 30 September 2008, USPTO issued a "Notice of Allowance" to CGactive LLC (U.S. Trademark

77,355,287) for "CloudOS". A cloud operating system is a generic operating system that "manage[s] the

relationship between software inside the computer and on the Web", such as Microsoft Azure. Good OS LLC

also announced their "Cloud" operating system on 1 December 2008.

Richard Stallman, founder of the Free Software Foundation, believes that cloud computing endangers liberties

because users sacrifice their privacy and personal data to a third party. In November 2007, the Free Software

Foundation released the Affero General Public License, a version of GPLv3 designed to close a perceived

legal loophole associated with free software designed to be run over a network, particularly software as a

service. An application service provider is required to release any changes they make to Affero GPL open

source code




CHAPTER 6

RISK MITIGATION

Corporations or end-users wishing to avoid not being able to access their data or even losing it should

research vendors' policies on data security before using vendor services. One technology analyst and

consulting firm, Gartner, lists seven security issues which one should discuss with a cloud-computing vendor:

1. Privileged user accessinquire about who has specialized access to data and about the hiring and

management of such administrators.

2. Regulatory compliancemakes sure a vendor is willing to undergo external audits and/or security

certifications.

3. Data locationsask if a provider allows for any control over the location of data.

4. Data segregationmake sure that encryption is available at all stages and that these "encryption

schemes were designed and tested by experienced professionals".

5. Recoveryfind out what will happen to data in the case of a disaster; do they offer complete

restoration and, if so, how long that would take.

6. Investigative Supportinquire whether a vendor has the ability to investigate any inappropriate or

illegal activity.

7. Long-term viabilityask what will happen to data if the company goes out of business; how willdata be returned and in what format.

In practice, one can best determine data-recovery capabilities by experiment: asking to get back old data

seeing how long it takes, and verifying that the checksums match the original data. Determining data security

is harder. A tactic not covered by Gartner is to encrypt the data yourself. If you encrypt the data using a

trusted algorithm, then regardless of the service provider's security and encryption policies, the data will only

be accessible with the decryption keys. This leads to a follow-on problem: managing private keys in a pay-on

demand computing infrastructure.




CHAPTER 7

KEY CHARACTERISTICS

Cost is greatly reduced and capital expenditure is converted to operational expenditure. This lowers

barriers to entry, as infrastructure is typically provided by a third-party and does not need to be

purchased for one-time or infrequent intensive computing tasks. Pricing on a utility computing basis is

fine-grained with usage-based options and minimal or no IT skills are required for implementation.

Device and location independence enable users to access systems using a web browser regardless o

their location or what device they are using, e.g., PC, mobile. As infrastructure is off-site (typically

provided by a third-party) and accessed via the Internet the users can connect from anywhere.

Multi-tenancy enables sharing of resources and costs among a large pool of users, allowing for:

o Centralization of infrastructure in areas with lower costs (such as real estate, electricity, etc.)

o Peak-load capacity increases (users need not engineer for highest possible load-levels)

o Utilization and efficiency improvements for systems that are often only 10-20% utilized.

Reliability improves through the use of multiple redundant sites, which makes it suitable for business

continuity and disaster recovery. Nonetheless, most major cloud computing services have suffered

outages and IT and business managers are able to do little when they are affected.

Scalability via dynamic ("on-demand") provisioning of resources on a fine-grained, self-service basis

near real-time, without users having to engineer for peak loads. Performance is monitored andconsistent and loosely-coupled architectures are constructed using web services as the system

interface.

Security typically improves due to centralization of data, increased security-focused resources, etc.

but raises concerns about loss of control over certain sensitive data. Security is often as good as or

better than traditional systems, in part because providers are able to devote resources to solving

security issues that many customers cannot afford. Providers typically log accesses, but accessing the

audit logs themselves can be difficult or impossible.

Sustainability comes about through improved resource utilization, more efficient systems, and carbon

neutrality. Nonetheless, computers and associated infrastructure are major consumers of energy.

CHAPTER 9

ARCHITECTURE

Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud

computing, comprises hardware and software designed by a cloud architectwho typically works for a cloud

integrator. It typically involves multiple cloud components communicating with each other over application

programming interfaces, usually web services.

This closely resembles the UNIX philosophy of having multiple programs doing one thing well and workingtogether over universal interfaces. Complexity is controlled and the resulting systems are more manageable

than their monolithic counterparts.

Cloud architecture extends to the client, where web browsers and/or software applications access cloud

applications.

Cloud storage architecture is loosely coupled, where metadata operations are centralized enabling the data

nodes to scale into the hundreds, each independently delivering data to applications or user.

CHAPTER 11

ROLES

11.1 Provider

A cloud computing provider or cloud computing service provider owns and operates live cloud computing

systems to deliver service to third parties. The barrier to entry is also significantly higher with capital

expenditure required and billing and management creates some overhead. Nonetheless, significant operationa

efficiency and agility advantages can be realized, even by small organizations, and server consolidation and

virtualization rollouts are already well underway. Amazon.com was the first such provider, modernizing its

data centers which, like most computer networks, were using as little as 10% of its capacity at any one time

just to leave room for occasional spikes. This allowed small, fast-moving groups to add new features faste

and easier, and they went on to open it up to outsiders as Amazon Web Services in 2002 on a utility

computing basis.

11.2 User

A user is a consumer ofcloud computing. The privacy of users in cloud computing has become of increasing

concern. The rights of users are also an issue, which is being addressed via a community effort to create a bill

of rights.

11.3 Vendor

A vendor sells products and services that facilitate the delivery, adoption and use of cloud computing. For

example:

Computer hardware (Dell, HP, IBM, Sun Microsystems)

o Storage (Sun Microsystems, EMC, IBM)

o Infrastructure (Cisco Systems)

Computer software (3tera, Hadoop, IBM, RightScale)o Operating systems (Solaris, AIX, Linux including Red Hat)

o Platform virtualization (Citrix, Microsoft, VMware, Sun xVM, IBM)




CHAPTER 12

STANDARDS

Cloud standards, a number of existing, typically lightweight, open standards, have facilitated the growth of

cloud computing, including:

Application

o Communications (HTTP, XMPP)

o Security (OAuth, OpenID, SSL/TLS)

o Syndication (Atom)

Client

o Browsers (AJAX)

o Offline (HTML 5)

Implementations

o Virtualization (OVF)

Platform

o Solution stacks (LAMP)

Service

o Data (XML, JSON)

o Web Services (REST)

Storage

o Database(Amazon Simple DB, Google App Engine BigTable Datastore)

o Network attached storage (MobileMe iDisk, Nirvanix CloudNAS)

o Synchronization (Live MeshLive Desktop component, MobileMe push functions)

o Web service (Amazon Simple Storage Service, Nirvanix SDN)




CHAPTER 13

BUILDING A PRIVATE CLOUD

13.1 What do I need ?

For a Private Cloud or Customer Cloud, whichever name you prefer, to have an effective IT as a Servic

offering requires some key elements to be in-place.

First you need a management tool that allows you to monitor the servers providing the virtualizatioservices. The tool should also allow you to easily move services around the machines, and ideall

provide you with guidance on what actions to take should resource become over utilised.

Secondly, you need a tool that allows for the Business units in your organization to be self-sufficient irequesting and managing their services, while at the same time provide you with a method to calculat

charge-back costs.

Windows Server 2008 R2 out-of-the-box does not provide all of these. It does have a number of managemen

features you will need, but for the complete solution you need to add:-

System Center Virtual Machine Manager 2008 R2 (SCVMM) System Center Virtual Machine Manager Self Service Portal 2.0 (SSP)

These two System Center products provide the management, monitoring and self-service capabilities neede

to run an IT as a Service operation.

SCVMM provides the core management functionality. Allowing you to go beyond the Hyper-V managemen

console in R2, you can group your servers into host groups and monitor more than one host at a time

Intelligent placement built into SCVMM helps you make the best decisions about where virtual machines (VMs

should go. SCVMM also provides a library service where you hold template images, ISO images and scripts tha

can be easily deployed to meet different requirements. Finally Performance Resource Optimization (PRO

provides you with the ability to monitor and correct problems for VMs. PRO allows the administrator to set u

information that can be displayed when certain thresholds are reached. These Tips, can, for example, have

messaging saying Add another Web Server to Order Tracking Web Farm.

SSP provides the self-service functionality. At a high level, once enabled and configured by the I

Administrator, SSP allows registered Business Units to manage their own administrative team to reques

resources, start or stop VMs and be entirely self-sufficient in managing their resources. At the back end, the IT

Administrator can set charge back costs for both reserved resources and allocated resources.




13.2 Where to Start ?

There are requirements for the installation to work. First, there are additional roles and features that need to

be installed on Windows Server 2008 R2. These are primarily driven by SCVMM. So to install SCVMM, Window

Server must have:

Hyper-V. The SCVMM Setup Wizard automatically adds this role, which will work as long as the machinbeing used supports virtualization.

Windows Remote Management (WinRM). For SCVMM setup to work, the service must be installed anin a state other than disabled and stopped.

Internet Information Services (IIS) 7.0. You must add the Web Server (IIS) role and then install thfollowing server role services:

o IIS 6 Metabase Compatibilityo IIS 6 WMI Compatibilityo Static Contento Default Documento Directory Browsingo HTTP Errorso ASP.NETo .NET Extensibilityo ISAPI Extensionso ISAPI Filterso Request Filtering

In addition to these, the SSP also requires some additional features be installed:

Microsoft Message Queuing (MSMQ). Windows PowerShell 2.0. This requirement supersedes version 1.0 that SCVMM requires. Microsoft .NET Framework 3.5 SP1. R2 contains 3.5.1, so if this is installed then you have met thi

requirement.

The final requirement for both SCVMM and SSP is a database. When installed alone, SCVMM can use the SQ

Express edition, which it will install automatically if you do not provide it with an alternative. However, SS

requires either Standard or Enterprise editions of SQL Server 2008 or higher.

The other requirement for the solutions is Active Directory. Both SCVMM and SSP work best in a domai

environment. As we go through SSP, it will become clear why this is so.

In my test environment Ive mixed and matched. The base OS is R2 Enterprise edition, the database server i

SQL Server 2008 R2 Standard edition. At this point that you may consider installing the beta of Service Pack

for Windows Server 2008 R2 to take advantage of the Dynamic Memory feature. This is an extremely usefu

feature for maximizing the memory usage on Hyper-V hosts; the caveat here is that the SSP documentatio

doesnt yet have any recommendation on how this feature interacts with the Charge-back process. I didn

install SP1 beta for that very reason, but I do encourage you to evaluate it for potential use on productio

Hyper-V hosts.




Figure: 13.1 Basic Private Cloud Architecture

13.3 Configuring various Components ?

ConfiguringSCVMM

Im going to start with SCVMM, since this is the core of the environment. Basically, to create a self-servicePrivate Cloud environment you need to configure the following:-

User Role group for the portal Add any base images and ISO files to the library Create templates of the workloads you want to offer. Next step is the creation of your templates. The templates are just preconfigured images that have been

generalized for easy deployment. So you can either take an existing VHD, or install a new OS, configure

it the way it needs to be. Then prepare it. On the VM menu, selecting New Template will take the image

and do all the work needed to generalize it. When you start this process the source image is destroyed. Soif you need a copy, now is a good time to take one.

The New Template Wizard asks for some basic information and the location where you want to store thetemplate. When you configured SCVMMs Library component during setup you created a share for thelibrary, within that share you can create a folder for templates to help organizes these files.




Once a template is created you have the minimum need to try out the self-service portal, which is whatwe will now configure.

Figure 13.2 : Configuring SCVMM

Configuring the Self-Service Portal

As the administrator, the first task is to configure the portal. Connecting to website as the administrator, you

need to configure just two of the four options on the Settings link. The main one is the Configure Datacenter

Management link, here you configure these properties.

VMM Server. This is the FQDN of the machine you installed the VMM server role on. Device. Configure the names any SANS or Load Balancers you have. Networks. These map to the names of the networks you configured in Hyper-V. The names here must

match those in the Virtual Network Manager in the Hyper-V console.

Active Directory. Add any Domains you have. Quota Cost. Enter the default values for memory and storage. You can alter these on a template basis

later.

Environment. Enter the names of any environments you want to use to group infrastructures in. This ispurely process and organization.

Save and close and you are almost set.

Next part is to configure the Templates. On the Template page enter the library server where youd like to get

the templates from. If the Self-Service Portal service is not running, this is the point you find out as service willnot return any information from the library server.
http://blogs.technet.com/cfs-file.ashx/__key/CommunityServer-Blogs-Components-WeblogFiles/00-00-00-62-96-metablogapi/1423.clip_5F00_image002_5F00_013B7E6D.jpg




Now you are ready to try out the configuration of Business Units, Infrastructures and Virtual Machines. As the

administrator you get to approve all requests, so while anyone could request a BU, you get the final say. Now, if

you are testing this, dont use really BU names because once you use than name you cant delete it later yet asI found setting up a demo.

So what do you configure? Ill run through the basics to get the system working on a test environment. On theBU registration, a lot of it is simply documentation; the administrators are the one area that interacts with VMM

Those names you enter here are added to the role we configured earlier. When submitted, the request appears as

an Onboarding request in the request queue.

Once approved, the BU can set up its infrastructures. From the first post, the diagram of what an infrastructure

consist of gives us a good idea of what the request process will cover. The request is a 3 step process:-

Configure the Infrastructure name. Configure the Service and Service Role Add Templates for the VMs.

Figure 13.3 : Configuring Self-Service Portal
http://blogs.technet.com/cfs-file.ashx/__key/CommunityServer-Blogs-Components-WeblogFiles/00-00-00-62-96-metablogapi/6765.clip_5F00_image008_5F00_2A935A7B.jpg




Configurethe Infrastructure nameThe first part asks for the infrastructure name, the priority, how long the BU expects to keep it and the forecast

for the capacity it will use. The capacity you enter here is used when calculating free space when starting VMs

or when creating new Services and Service roles. If you exceed the capacity later, you will need to enter anInfrastructure change request to change the capacity.

Configure the Service and Service Role

In the Service and Service Roles we set out how the Infrastructure is set up. We provide the name of the service,add it to the environment. The environment is the list we added earlier when setting up the portal. The billing

code and datacenter are names you use internally. Its when you get to the Service Quota you start to useinformation from the other pages. As mentioned above, the Infrastructure capacity on the first page is used as the

cap for Services and Roles.

The networks are those setup earlier or you can be request them on this page. These have to match the name usein the Hyper-V Virtual Network Manager. The services can have their own access control; you can enter

additional admins to those for the BU, plus members who can access this service.

The service role is tucked away at the end, all you need to enter is the Role name and the number of images itneeds. The rest for our test environment can be left to their default.

Add Templates for the VMs

The final part of the infrastructure request is to assign the templates to this request. The list you get is the onefrom the template settings for the portal. Here selecting the templates available are the ones that will be available

when the BU tries to create VMs. If the template is not selected here and is needed later then a newInfrastructure change request needs to be created.

Once approved the virtual machine creation can begin and the billing starts.

Creating Virtual Machines

Weve now got to the point where BU can request Virtual Machines and manage their environment. The control

on resources comes in here, when requesting a VM you are asked for the number of machines, their names, the

infrastructure details and template to use. If they exceed the resources, the creation process stops. BUs cant sayone thing about capacity and do something else.

Once created the VMs are managed and controlled from the VM page, all members of the BU Roles can start orstop the VMs created. You can also monitor the jobs from the Jobs page or as a DC Administrator the SCVMM

console.




CHAPTER 14

CONCLUSION

Cloud Computing is a vast topic and the above report does not give a high level introduction to it. It is

certainly not possible in the limited space of a report to do justice to these technologies. What is in store for

this technology in the near future? Well, Cloud Computing is leading the industrys endeavor to bank on this

revolutionary technology.

Cloud Computing Brings Possibilities..

Increases business responsiveness

Accelerates creation of new services via rapid prototyping capabilities

Reduces acquisition complexity via service oriented approach

Uses IT resources efficiently via sharing and higher system utilization

Reduces energy consumption

Handles new and emerging workloads

Scales to extreme workloads quickly and easily

Simplifies IT management Platform for collaboration and innovation

Cultivates skills for next generation workforce

Today, with such cloud-based interconnection seldom in evidence, cloud computing might be more accurately

described as "sky computing," with many isolated clouds of services which IT customers must plug into

individually. On the other hand, as virtualization and SOA permeate the enterprise, the idea of loosely coupled

services running on an agile, scalable infrastructure should eventually make every enterprise a node in the

cloud. It's a long-running trend with a far-out horizon. But among big metatrends, cloud computing is the

hardest one to argue with in the long term.
