Microsoft Windows Azure
Windows Azure lets developers deploy applications across a global network of Microsoft-managed data centers, offering a 99.5 percent uptime SLA. Applications can be developed via technologies like ASP.net, PHP, and Node.js. Developers can also host Apache Tomcat servers and JVMs via worker roles, while an Azure SDK for Java enables Java development. Microsoft recently added a video delivery service, Windows Azure Media Services, to its Azure arsenal, and Azure also features SQL Azure database services as well as services for storage, business analytics, caching, identity secure messaging, and content delivery. The Windows Azure HPC Scheduler eases development of compute-intensive parallel applications. Also, developers can list Windows Azure applications on the Windows Azure Marketplace.
