Microsoft Azure - Cloud Computing

Microsoft Azure is a cloud operating system and a platform for developing applications in the cloud. Applications in Azure are organized around the concept of roles, which identify a distribution unit for applications and embody the application’s logic. Currently, there are three types ofrole: Web role, worker role, and virtual machine role. The Web role is designed to host a Web application, the worker role is a more generic container of applications and can be used to perform workload processing, and the virtual machine role provides a virtual environment in which the computing stack can be fully customized, including the operating systems.
