Windows Azure is a cloud services operating system that serves as the development, service hosting and service management environment for the Windows Azure platform. Windows Azure provides developers with on-demand compute and storage to host, scale, and manage web applications on the internet through Microsoft datacenters. Windows Azure is a flexible platform that supports multiple languages and integrates with your existing on-premises environment. To build applications and services on Windows Azure, developers can use their existing Microsoft Visual Studio expertise. In addition, Windows Azure supports popular standards, protocols and languages including SOAP, REST, XML, Java, PHP and Ruby. Windows Azure SDK and Windows Azure Tools for Microsoft Visual Studio (64-bit) extend Visual Studio 2010 to enable the creation, configuration, building, debugging, running, packaging and deployment of scalable web applications and services on Windows Azure.
