The document outlines the evolution of Microsoft's cloud computing platform Windows Azure from 2007 to 2011. It started as Project Red Dog in 2007 supporting PHP and Java on full trust virtual machines. In 2009, Azure was launched with partial trust web and worker roles running only .NET. The first Community Technology Preview of Azure was released in 2008 and the platform officially launched in 2010. Over time Azure added more features like remote desktop, startup tasks, and cross-platform SDKs for Java and Node.js.
