Azure Virtual Machines vs HHVM (HipHop Virtual Machine): What are the differences?

Developers describe Azure Virtual Machines as "It provides on-demand, high-scale, secure, virtualized infrastructure *". You can create Linux and Windows virtual machines. It gives you the flexibility of virtualization for a wide range of computing solutions—development and testing, running applications, and extending your datacenter. It’s the freedom of open-source software configured the way you need it. On the other hand, *HHVM (HipHop Virtual Machine)** is detailed as "An open-source virtual machine designed for executing programs written in Hack and PHP". HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC.
