Websites
Azure Websites is a robust cloud platform for developing, testing, and running web apps. Build apps using your favorite tools and languages—.NET, Java, PHP and Node.js.—then deploy them to a load-balanced platform that scales automatically, can be secured with Active Directory, and connects seamlessly to your on-premises resources. Azure Websites handles platform chores like availability, maintenance, and patching, so you have more time for your apps.
