CloudOpen 2022

Who wouldn't want to own their own little cloud, running only their own instances on their own hardware, yet still benefiting from a highly available environment including distributed storage and networking. This is what we'll be exploring in this talk, combining LXD as a self-hosted mini-cloud with CEPH for storage and OVN for network. That combination allows for a fully redundant deployment on as little as 3 machines and can run hundreds or thousands of containers or virtual machines, be managed from anywhere and run just about any workload you can think of (GPU and all included). Whether you want something like this as a homelab running on some Raspberry Pis or running it in a co-location facility with a few small servers or deploying it at the edge, you always get the same thing, something which feels like a cloud but that you fully own and can easily reshape to your liking. This talk will start by going over what LXD, CEPH and OVN are, how they can work together to provide a highly available deployment on as little as 3 machines and then will go over how to actually deploy this in just a few minutes on low cost hardware.
