Software as a Service ('''SaaS''') is a model of Software Delivery where a company adopts specific activities that provide customers access to software alleviating that customer from the maintenance and daily technical operation and support of business and/or consumer software. SaaS is a model of software delivery rather than a market segment; software can be delivered using this method to any market segment including home consumers, small business, medium and large business. KEY CHARACTERISTICS OF SOFTWARE DELIVERED BY SAAS The key characteristics of SaaS software, according to analyst IDC include:
TYPES OF SAAS PROVIDERS There are two types of SaaS providers. The first has often been referred to as an Application Service Provider (ASP) where a customer purchases and brings to a hosting company a copy of software, or the hosting company offers widely available software for use by customers, such as hosting Microsoft Office and making that available across the web to customer who pay a fee per month for access to the software. The second type of SaaS provider offer what is often called Software On-demand , where a company offers to customers software specifically built for one-to-many hosting. This means that one copy of the software is installed for use by many companies who access the software across the web. In the first of these types of providers, a licensing fee and a monthly fee are quite separate being paid to the maker of the software and the hoster of the software as appropriate. The second type of hosting is where there is no division between licensing and hosting fees, and where there is little to no customization of software for each customer. ASP VERSUS SAAS The reason for moving away from the term ASP or Application Service Provider is that the ASP generation was merely traditional client-server applications with HTML front ends added as an afterthought. These applications were hosted by third-parties who ordinarily did not have application expertise, but were managed servers. Because the applications were not written as net-native applications, performance was poor and application updates were no better than self managed applications. By comparison, current net-native SaaS applications or independent portions are updated regularly, many daily. SAAS PROVIDERS --->
