CloudTest and Amazon EC2 Instances

CloudTest uses Hardware Virtual Machine (HVM) instead of Paravirtual (PV) across the board for Amazon Machine Images (AMI). This applies to Grids, Results Databases, and Environments. HVM is the new generation of virtualization technology offered by Amazon. More detail about HVM technology can be found in the Amazon EC user guide's Virtualization Types article.

The translation of CloudTest server sizes to Amazon EC2 instance types is as follows:
