Software as a Service (SaaS)

Software as a Service (SaaS) is based on a simple model that 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.

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.
