Planning Considerations for Externalization and Cloud Computing
12 October 2009
 
Mike Rollings  

The cloud has become a catch-all term for what once were independent concepts. The definition of "the cloud" encompasses various layers of functionality, including software as a service (SaaS), platform as a service (PaaS), infrastructure as a service (IaaS), and hardware infrastructure as a service (HIaaS). The purpose of the cloud is to create an IT environment without boundaries, where services can be dynamic, movable, elastic, composable, and consumption-based. But the cloud is currently a moving target. In this syllabus, Research Director Michael Rollings discusses planning considerations for realizing the promise of the cloud and for the creation of tomorrow's business solutions by mixing internal and external services.
