Cloudcraft vs HHVM (HipHop Virtual Machine): What are the differences?
Developers describe Cloudcraft as "Draw AWS diagrams". Cloudcraft is service for creating powerful AWS diagrams for free, used by software architects and developers. You can create cloud architecture diagrams, service deployment plans, illustrate software documentation, presentations etc. 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.
Cloudcraft belongs to "Architecture Design Tools" category of the tech stack, while HHVM (HipHop Virtual Machine) can be primarily classified under "Virtual Machine".
