Windows Azure
Windows Azure is a Microsoft cloud computing platform used to build, deploy and manage applications through a global network of Microsoft-managed datacenters. Windows Azure allows for applications to be built using many different programming languages, tools or frameworks and makes it possible for developers to integrate their public cloud applications in their existing IT environment. Windows Azure provides both Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) services and is classified as the “Public Cloud” in Microsoft"s cloud computing strategy, along with its Software as a Service (SaaS) offering, Microsoft Online Services
- Web sites - High density hosting of web sites. This feature was announced in preview form in June 2012 at the Meet Windows Azure event.[2] Customers can create web sites in PHP, .NET, and Node.js, or select from several open source applications from a gallery to deploy. This comprises one aspect of the Platform as a Service (PaaS) offerings for the Windows Azure Platform.
- Virtual machines - Announced in preview form at the Meet Windows Azure event in June 2012[2] the Windows Azure Virtual Machines comprise the Infrastructure as a Service (IaaS) offering from Microsoft for their public cloud. Customers can create Virtual Machines, of which they have complete control, to run the Microsoft Data Centers. As of the preview the Virtual Machines supported Windows Server 2008 and 2012 RC operating systems and a few distributions of Linux.
- Cloud services - Previously named "Hosted Services", the Cloud Services for Windows Azure comprise one aspect of the PaaS offerings from the Windows Azure Platform. The Cloud Services are containers of hosted applications. These applications can be internet-facing public web applications (such as web sites and ecommerce solutions), or they can be private processing engines for other work, such as processing orders or analyzing data.
- Developers can write code for Cloud Services in a variety of different programming languages; however, there are specific software development kits (SDKs) started by Microsoft for Python, Java, node.JS and .NET.[3] Other languages may have support through Open Source projects. Microsoft published the source code for their client libraries on GitHub.[4]

Implementation
Windows Azure uses a specialized operating system, called Windows Azure, to run its "fabric layer" — a cluster hosted at Microsoft"s datacenters that manages computing and storage resources of the computers and provisions the resources (or a subset of them) to applications running on top of Windows Azure. Windows Azure has been described as a "cloud layer" on top of a number of Windows Server systems, which use Windows Server 2008 and a customized version of Hyper-V, known as the Windows Azure Hypervisor to provide virtualization of services. Scaling and reliability are controlled by the Windows Azure Fabric Controller so the services and environment do not crash if one of the servers crashes within the Microsoft datacenter and provides the management of the user"s web application like memory resources and load balancing
