However, this rapidly changes when you are confronted with edge cases: people living in less well-connected countries, or, in our case, needing to run hundreds or even thousands of virtual machines for automated test cases over a VPN. Recently, we started working on the oVirt Terraform Provider, which has unfortunately seen better days. Apart from getting our own very much […]
