The SAAS delivery model

Software providers quickly recognized a better way to deliver software from a data center and SAAS was born. The SAAS model uses multitenant architecture, which means SAAS customers share common parts of the application while their data and business process configurations are stored separately. A hallmark of SAAS is subscription pricing, which includes the use of the software, support and access to all upgrades, patches and service packs.

Cloud computing refers to the use of shared computing resources that provide storage, compute cycles and redundancy on an on-demand, pay-per-use basis. In the cloud, an application instance can be instantly provisioned and decommissioned as needed, allowing for rapid scaling and recovery from outages or failures.

Today, the term "SAAS" encompasses any application that is delivered as a service via a Web browser, whether from a vendor's data center, a public cloud or even a private cloud. Now, let's examine why SAAS is an attractive option for application delivery for the SMB.
