In this post I will look at the three different service models for cloud computing as defined by NIST. More specifically I will look at the management and operations overhead for each one of the models and compare it to the traditional on-premise model.

Traditionally enterprises have been responsible for managing their own IT infrastructure as well as the software stack that runs their applications.

There are thousands of articles on the Internet that discuss which applications are applicable for the cloud (including several that I have ... (more)
