We are looking into setting up Virtual Web Gateway appliances as a backup to our physical appliance. I have been searching for best practice specifications/configurations for a virtual machine but have not found any official documentation on the subject. Can someone direct me to this documentation if it exists?
There are some specs in the product guide.
mount in ESXi to an instance that mimics your physical hardware
All resource allocation sohuld be exclusively to MWG, don't overprovision the server
For best performance of the virtual instance, disable caching in the proxy.
that's about it...
