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 :

    Product Companies : Can tap new markets, Flexible pricing, Revenue across the year,Ease of adding new features
    Enterprises: Rapid development, Reduced Risk,Low investment,Billing by usage,Immeadiate ROI

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
