Centralized hosting of business applications dates back to the 1960s. Starting in that decade, IBM and other mainframe computer 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 ...
The cloud (or SaaS) model has no physical need for indirect distribution because it is not distributed physically and is deployed almost instantaneously, thereby negating the need for traditional partners and middlemen. Unlike traditional software, which is conventionally sold as a perpetual license with an up-front cost (and an optional ongoing su...
Most SaaS providers offer a multi-tenant 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 can be installed on multiple machines (called horizontal scaling). In some cases, a second vers...

Because data is stored on the vendor's servers rather than on-premises, data security becomes an issue, particularly with intellectual property. 2. SaaS applications are hosted in the cloud, far away from the application users. This introduces latenc...

Similar to source code escrow, where critical software source code is stored with an independent third party, SaaS data escrow applies the same logic to the data within a SaaS application. It allows ...
One notable criticism of SaaS comes from Richard Stallman of the Free Software Foundation, who refers to it as Service as a Software Substitute (SaaSS). He considers the use of SaaSS to be a violation of the principles of free software.According to Stallman:
The Battle of Villers-Bocage took place in Normandy, France, on 13 June 1944 during World War II. Following the D-Day landings on 6 June, the Germans established defences in front of Caen. The British attacked to attempt to exploit a gap in the German defences west of the city. They reached Villers-Bocage without incident in the morning but ...
