HistoryeditCentralized hosting of business applications dates back to the 1. Starting in that decade, IBM and other mainframe providers conducted a service bureau business, often referred to as time sharing or utility computing. Such services included offering computing power and database storage to banks and other large organizations from their worldwide data centers. The expansion of the Internet during the 1. Application Service Providers ASP. ASPs provided businesses with the service of hosting and managing specialized business applications, with the goal of reducing costs through central administration and through the solution providers specialization in a particular business application. Two of the worlds pioneers and largest ASPs were USI, which was headquartered in the Washington, DC area, and Futurelink Corporation, headquartered in Irvine, California. Software as a Service essentially extends the idea of the ASP model. The term Software as a Service Saa. S, however, is commonly used in more specific settings While most initial ASPs focused on managing and hosting third party independent software vendors software, as of 2. Saa. S vendors typically develop and manage their own software. Driver Logitech Quickcam Express Win Xp. Renting To Government Programs. Whereas many initial ASPs offered more traditional client server applications, which require installation of software on users personal computers, Saa. S solutions of today rely predominantly on the Web and only require a web browser to use. Whereas the software architecture used by most initial ASPs mandated maintaining a separate instance of the application for each business, as of 2. Saa. S solutions normally utilize a multitenant architecture, in which the application serves multiple businesses and users, and partitions its data accordingly. The acronym allegedly first appeared in an article called Strategic Backgrounder Software As A Service, internally published in February 2. Software Information Industry Associations SIIA e.

S model has no physical need for indirect distribution because it is not distributed physically and is deployed almost instantaneously, therefore partners and middlemen of the traditional kind are not necessary. However, as the market has grown, Saa. S and managed service players have been forced to try to redefine their role. PricingeditUnlike traditional software, which is conventionally sold as a perpetual license with an up front cost and an optional ongoing support fee, Saa. S providers generally price applications using a subscription fee, most commonly a monthly fee or an annual fee. Consequently, the initial setup cost for Saa. S is typically lower than the equivalent enterprise software. Saa. S vendors typically price their applications based on some usage parameters, such as the number of users using the application. However, because in a Saa. S environment customers data reside with the Saa. S vendor, opportunities also exist to charge per transaction, event, or other unit of value, such as the number of processors required. The relatively low cost for user provisioning i. Saa. S vendors to offer applications using the freemium model. In this model, a free service is made available with limited functionality or scope, and fees are charged for enhanced functionality or larger scope. Some other Saa. S applications are completely free to users, with revenue being derived from alternative sources such as advertising. A key driver of Saa. S growth is Saa. S vendors ability to provide a price that is competitive with on premises software. This is consistent with the traditional rationale for outsourcing IT systems, which involves applying economies of scale to application operation, i. ArchitectureeditThe vast majority of Saa. S solutions are based on a multitenant architecture. With this model, a single version of the application, with a single configuration hardware, network, operating system, is used for all customers tenants. To support scalability, the application is installed on multiple machines called horizontal scaling. In some cases, a second version of the application is set up to offer a select group of customers with access to pre release versions of the applications e. This is contrasted with traditional software, where multiple physical copies of the software each potentially of a different version, with a potentially different configuration, and often customized are installed across various customer sites. In this traditional model, each version of the application is based on a unique code. Although an exception rather than the norm, some Saa. S solutions do not use multitenancy, or use other mechanismssuch as virtualizationto cost effectively manage a large number of customers in place of multitenancy. Whether multitenancy is a necessary component for software as a service is a topic of controversy. There are two main varieties of Saa. S Vertical Saa. SA Software which answers the needs of a specific industry e. Horizontal Saa. SThe products which focus on a software category marketing, sales, developer tools, HR but are industry agnostic. CharacteristicseditAlthough not all software as a service applications share all traits, the characteristics below are common among many Saa. S applications Configuration and customizationeditSaa. S applications similarly support what is traditionally known as application configuration. In other words, like traditional enterprise software, a single customer can alter the set of configuration options a. Each customer may have its own settings or parameter values for the configuration options. The application can be customized to the degree it was designed for based on a set of predefined configuration options. For example to support customers common need to change an applications look and feel so that the application appears to be having the customers brand orif so desiredco branded, many Saa. S applications let customers provide through a self service interface or by working with application provider staff a custom logo and sometimes a set of custom colors. The customer cannot, however, change the page layout unless such an option was designed for. Accelerated feature deliveryeditSaa. S applications are often updated more frequently than traditional software,2.
