Abstract - Software as a Service (SaaS) is a software
distribution model[1] in which are hosted by a service or
vendor provider and over the network made available to
customers, typically the Internet. SaaS is a prevalent
delivery model that supports Web services and serviceoriented architecture (SOA)[4] mature and new
developmental approaches.
Around the world broadband services are available to
support user access from more areas. SaaS is closely related
on demand computing software delivery and ASP
(application service provider) models. For SaaS, IDC
identifies two slightly different delivery models. It is similar
to ASP for the hosted application management (hosted AM)
model: For customers it delivers over the Web, and a
provider hosts commercially[3] available software. The
provider gives customers network-based access to a single
copy of an application created specifically for SaaS
distribution for the software on demand model.
SaaSprovides licenses an application to customers either as
a service on demand, through a subscription, in a “pay-asyou-go” model, or (increasingly) at no charge. To generate
revenue from streams other than the user, such as from user
list sales or advertisement, SaaS is a rapidly growing
market as indicated in recent reports that predict ongoing
double digit growth. This rapid growth indicates that SaaS
will become commonplace within every organization and
hence it is important that buyers and users of technology[4]
understand where it is suitable and what SaaS is.
Key Words: SOA, Hosted AM, SaaS etc…
1. INTRODUCTION
Software as a Service (SaaS) is a software delivery method
that provides access to software and its functions remotely as a
Web-based service[4]. To access business functionality,
Software as a Service allows organizations[2]at a cost typically
less than paying for licensed applications since SaaS pricing is
based on a monthly fee.

Because of the software is hosted remotely, users don't need to
invest in additional hardware[3]. To handle the installation,
set-up and often daily upkeep and maintenance, Software as a
Service removes the need for organizations. Software as a
Service may also be referred to as simply hosted applications.
2. TYPES OF SAAS
Business Utility SaaS -Providing actionable analysis and
streamlining collaborative processes, Sales force automation
applications are used by businesses and individuals for
managing[2] and collecting data. Customer Relationship
Management (CRM), Human Resources and Accounting are the
popular use cases.
Social Networking SaaS - Applications are used by individuals
for networking and sharing information, photos, videos, etc.
like Facebook.

2.1 Characteristics of SaaS
2.3 Drawbacks of SaaS
It is important for Cloud Computing, to ensure that solutions
sold as SaaS in fact comply with generally accepted definitions.
Robustness:
Due to browser limitations, SaaS may not be as robust
(functionality wise) as traditional[4] software
applications. Consider Google Doc & Microsoft Office.
Privacy:
Having all of a user’s data sit in the cloud raises security &
privacy concerns. SaaS providers are usually the target of
hack[3] exploits.
From China in the last several years, Google servers have
been the target of exploits purportedly.
Security:
Malicious code detection and attack detection.
Reliability:
Wide range of dependent clients could be affected, in the
rare event of a SaaS provider going down. For example,
when AmazonEC2[4] service went down in April 2011, it
took down Foursquare, Reddit, Quora and other wellknown applications that run on it.
Fig - 2: Cloud Computing Services.
Characteristics of SaaS include,
Commercial[2] software for Web access.
A central location, managed by software.
“One to Many” model of Software delivers.
To handle software upgrades and patches, users not
required.
APIsallows integration between different pieces of
software.
2.2 Advantages of SaaS
Easy to use:SaaS applications do not require more than a
web browser.
Cheap: SaaS makes it affordable to small businesses and
individuals for the pay as you go pricing model.
Scalability: To meet consumer[1] demand, SaaS
application can be easily scaled up or down. To scale up,
Consumers do not need to worry about additional
computing infrastructure.
Since data is being stored in the cloud, Applications are
less prone to data loss.
SaaS applications are less clunky, compared to traditional
applications. They do not require users to
install/uninstall binary code on their machines.SaaS
applications are able to run on a wide variety of devices,
due to the delivery nature of Sass through the internet.
For better collaboration between teams since the data is
stored in acentral location.
Much faster of change in Velocity[2] for SaaS applications.
SaaS favors anagile development life cycle.
Software changes and frequent and on-demand.

3. CONCLUSION
Over a variety of services from Infrastructure as a Service at
the base, through Platform as a Service as a development tool
and through to Software as a Service replacing on-premise
applications, cloud computing doesn’t describe a single thing. It
is important to understand[1] the different aspects of Cloud
Computing and to assess their own situation and decide which
types of solutions are appropriate for their unique needs when
organizations looking to move to Cloud Computing. Cloud
Computing is a rapidly[3] accelerating revolution within IT and
will become the default method of IT delivery moving into the
future – organizations would be advised to consider their
approach towards beginning a move to the clouds sooner,
rather than later.
