• Definition: Software as a Service (SaaS), a.k.a. ondemand software, is a software delivery model in which software and its associated data are hosted centrally and accessed using a thin-client, usually a web browser over the internet. – Wikipedia • Simply put, SaaS is a method for delivering software that provides remote access to software as a webbased service. The software service can be purchased with a monthly fee and pay as you go.

Applicability of SAAS

Advantages of SaaS
00:38
Easy to use – Most SaaS applications do not require more than a web browser to run Cheap- The pay as you go pricing model of SaaS makes it affordable to small businesses and individuals. Scalability: SaaS application can be easily scaled up or down to meet consumer demand. Consumers do not need to worry about additional computing infrastructure to scale up. Applications are less prone to data loss since data is being stored in the cloud. Compared to traditional applications, SaaS applications are less clunky. They do not require users to install/uninstall binary code on their machines. Due to the delivery nature of Sass through the internet, SaaS applications are able to run on a wide variety of devices. Allows for better collaboration between teams since the data is stored in a central location. Velocity of change in SaaS applications is much faster. SaaS favors a Agile development life cycle. • Software changes and frequent and on-demand. Most Saas services are updated about every 2 weeks and users are most time unaware of these changes.

Disadvantages of SaaS
00:47
Type hereRobustness: SaaS software may not be as robust (functionality wise) as traditional software applications due to browser limitations. 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 exploits e.g. Google servers have been the target of exploits purportedly from China in the last several years Security Attack detection, malicious code detection Reliability In the rare event of a SaaS provider going down, a wide range of dependent clients could be affected. For example, when Amazon EC2 service went down in April 2011, it took down FourSquare, Reddit, Quora and other well known applications that run on it. We shall discuss each of these issues in more details in the next section

Summary
00:53
SaaS greatly enhances the ability of developers to scale their application on demand and better suite customer needs. I t encourages Agile practices by enabling providers deliver frequent updates/patches without waiting for major release cycles as in traditional applications. SaaS applications however are susceptible to privacy, security and reliability concerns. Hybrid environments combining both SaaS and traditional application methodologies may be useful in scenarios of extremely sensitive data or where constant up-time must be maintained.
