It’s more of a deployment and marketing technique than a software development methodology or architecture — delivering “Software as a Service” instead of as a product. On the plus side, it ensures an ongoing relationship between vendor and customer; on the minus side, it can be a painful lock-in for a client and a constant support headache for a vendor.
Google Apps is a prototypical example of SaaS — it’s an office productivity application that relies heavily on vendor-hosted functionality and is delivered via the Web. Other forms of SaaS include pure-API services like PayPal Virtual Terminal which are intended to provide functionality to be integrated with a customer’s existing line-of-business system. In the degenerate case, even a fairly ordinary software application such as an electronic medical office software suite may be viewed as a partial SaaS offering because such software is nearly useless without a constant stream of updates delivered to account for the rapidly-changing pharmaceutical and billing landscapes.
