What is “Cloud” and what is SaaS
Often SaaS and Cloud are mixed up – let’s get the context correct
� “Cloud” is the use of computing resources that are delivered as a service over a network -
typically the internet.
� There are a number of different types of services offered in the cloud today:
SaaS is Application SW delivered as a Service over a network.
PaaS/ IaaS – Platform/Infrastructure
BPaaS – Business Process (including marketing)
DBaaS - DataBase
DaaS – Data
SCaaS – Security
TEaaS – Testing

Architecture: SaaS
Customer choices
Customer can:
� Replace their existing business systems partially or completely with Oracle SaaS applications
� Add new applications to their existing IT landscape (e.g. Fusion SaaS Compensation)
� Significantly extend existing Oracle SaaS applications (e.g. Fusion HCM with Taleo Recruiting)

How SaaS Changes the approach
� It appears at first glance to be a technical change - creating shared software
that runs in an external datacenter rather than an application for each
customer’s datacenter
� It is much more than a technical change, it requires a different implementation
and business approach,
� It’s a service not a product
� Adopt the Business processes not adapt
� Work on scope, release driven.

How SaaS Changes the business
� Among the things that can change are
� What doesn’t change?
� We STILL need to have a good understanding of our customers and what they want to achieve!
What changes How does it change
How products are priced Subscription based
How products are sold A lot more business interaction and selling one total solution
How they are implemented � Faster implementations as they are more standard process driven
� With more offshore (up to 70/ 80% SSI) for all technical / data
loading and integration work
How the service is being provided and
maintained by the software vendor
� More regular upgrades to get the latest features
� SLA

Benefits and Risks for Customers
Organizations that buy SaaS applications are diverse, ranging from two-person firms to global
enterprises. Yet the things they like and don’t like about SaaS tend to be much the same.
SaaS Benefits for Customers SaaS Risks for Customers
SaaS allows faster deployment, because no On-Premise
installation is required. Rather than wait weeks or months for
software to be deployed and configured on its own servers,
an organization can directly access the application in the
cloud.
Using SaaS requires trusting an outside provider for the
application’s availability and security. Most SaaS providers
don’t let their customers physically examine the details of
how they provide security. Instead, those customers must
learn to trust the SaaS provider, something that can take
time.
SaaS typically offers usage-based pricing, such as per user
per month, letting customers pay only for what they use.
Rather than estimating its needs, then buying a license in
advance, an organization can pay only for what it actually
uses.
SaaS can raise legal/regulatory concerns with storing data
outside the customer’s premises. Many countries have laws
and regulations about where some kinds of data can be
stored and how it must be handled. SaaS applications can run
afoul of these, especially when the SaaS application’s
datacenter and the customer are in different countries.

Benefits and Risks for Customers – cont.
SaaS Benefits for Customers SaaS Risks for Customers
A SaaS application has less financial risk than an On-Premise
application. Most cloud applications offer try-before-you-buy
options, so a customer can be sure the application has
business value before paying for it. Pay-as-you-go pricing also
brings less risk than a typical large up-front license fee.
A SaaS application can limit customization if many
customers share a single multi-tenant application. Multi-
tenancy, with multiple customers using the same instance of
software, lowers costs, but it also constrains how different
that software can appear to those customers. While SaaS
vendors often provide configuration options, a licensed on-
premises application is typically more customizable.
SaaS reduces the need for On-Premise resources, such as
servers and IT staff. Because the software runs in the cloud,
customers don’t need to invest in the hardware and people
to run and manage the application on premises.
SaaS applications can be harder to integrate with existing
On-Premise applications. Connecting applications within a
single datacenter is often challenging. When some of those
applications are running in the cloud, integration can get
even harder.
SaaS applications offer easier upgrades, with no On-Premise
software to update. Instead, the SaaS provider deploys
upgrades to a centrally managed copy. This makes it easier
for customers to get the benefits of new features added to
an application.
SaaS can have lower performance than On-Premise
applications. This issue appears most frequently when
network bandwidth between the customer and the SaaS
application’s datacenter is limited, and so how much it
matters commonly depends on geography.
