SOFTWARE AS A SERVICE (SAAS)

In this model, applications are hosted by a vendor or service

provider and made available to customers over a network, typically the

Internet. The traditional model of software distribution, in which software

is purchased and installed on personal computers, is sometimes referred

to as software as a product.

SaaS is gaining popularity as the underlying technologies that

support web services and service-oriented architecture (SOA) are

maturing, and broadband Internet access is increasingly available in many

parts of the world.

SaaS model can have two variations: hosted application

management and software on demand. In hosted application management,

a provider hosts commercially available software for customers and

delivers it over the Web. In the software on demand model, the provider

provides its customers access over the network to a single copy of

software application created specifically for SaaS distribution.

SaaS provides many benefits, e.g. easier administration, automatic

software updates and patch management, easier collaboration,

compatibility, low entry cost and risk for customers, increased customer

software security, and global accessibility.
