Do you remember Vagrant? It was that last hipster thing before Docker turned into the most recent hipster thing! It's also still really helpful for software evaluations or lab environments. Normally, it works with VirtualBox on your laptop, but this approach can be too limiting. Even running just 10 VMs becomes a stretch on a laptop. It burns through your battery, SSD lifetime, disk space and threatens how many dozen browser tabs you can open... Enter the Vagrant OpenNebula providers! You can actually control Vagrant on your workstation but have the VMs running on your cloud. There are multiple ways to do that, and also limitations. In the workshop, we'll look at what is possible and how you can best benefit from - oh right! - your cloud!
