NIST defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. My own definition is slightly to the point, I consider cloud computing as Information Technology as a Utility Service. To be clear, I find Cloud Computing no different than Managed Services. It doesn’t matter if you utilize software as a service, platform as a service, or infrastructure as a service, the idea is to treat IT as a utility service to save overall costs.
