The demand for Web development skills needed to design, build and deploy Software as a Service applications should continue to increase over the next several years as more companies seek solutions tailored to the capabilities of the cloud.

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular.
