VMware Unified Access Gateway: Horizon Deployment
KB ID 0001605 Problem With older versions of Horizon View, we simply deployed another Connection server and called it a Security Server. The drawback of that is, it requires another Windows licence. You can now deploy VMware UAG (Unified Access Gateway), try to think of it as a ‘Netscaler for VMware’, and like other VMware solutions it’s a small appliance built on VMware’s ‘Photon’ Linux.

KB ID 0001601 Problem I use EVE-NG a lot, it’s an awesome tool. Also I’m lucky enough to have my own ESX servers, so that’s where it lives.
