Windows Azure is an open and flexible cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed datacenters. It provides automatic OS and service patching, built in network load balancing and resiliency to hardware failure. You can build applications using any language, tool or framework. The Windows Azure client libraries are available for multiple programming languages, and are released under an open source license and hosted on GitHub. With Windows Azure, it is also easy to integrate your public cloud applications with your existing IT environment.
