Infrastructure-as-a-Service (IaaS) has brought a revolution to the use of computing resources. In the past, resource provisioning commonly took weeks or months. IaaS has reduced these timeframes to hours, or even minutes.
Inevitably, the IaaS revolution must be matched by a restructuring of the way applications are designed and delivered. Using Platform-as-a-Service (PaaS), organizations can reduce application lifecycles as dramatically as they used IaaS to reduce infrastructure timeframes. Of the numerous PaaS offerings available, Cloud Foundry has the largest ecosystem, which includes the enterprise-level distribution Stackato by ActiveState.
Cloud Foundry reduces application lifecycles in numerous ways. First, it provides preconfigured resources that are commonly used by applications, such as database services that support MySQL. It also provides an easy deployment mechanism. Compared to deploying in an IaaS environment, in which each application deployment requires individual resource provisioning, deploying on Cloud Foundry can be accomplished with a single command.
