Software as a Service
Software as a Service (SaaS) is based on a simple model. It allows the delivery of an application via a subscription model over the Internet. In the SaaS model, the customer does not take ownership of the software but rather ‘subscribes’ to a comprehensive solution that is delivered remotely over the Internet. No infrastructure investments, no maintenance costs!
A recent IDC SaaS forecast pegs the worldwide spend on SaaS to touch $14 billion by 2011.
The benefits of SaaS are manifold :
So what are some of the key criteria that define a robust SaaS application?
 |
Scalability : The application architecture should be able to scale up to the rising business demands by simply adding or removing servers, without the need to alter the application software architecture
|
|
Configurability : The application should be configurable, to ensure ease of maintenance
|
|
Security : The application should have adequate provision for data security, authentication, and authorization for each customer
|
|
Multi-tenancy : A single instance of the application should be able to support multiple tenants concurrently
