Migrating from Legacy with Ease, a.k.a. Cilium in Openstack and More - Ondrej Blazek, Seznam.cz

Everybody knows Kubernetes, that's what this is all about, right? But most companies do not run everything in k8s, they might have legacy applications or databases that are difficult to run in k8s. What if some of them are in something like OpenStack or directly on baremetal? What if part of then are running in k8s with Calico and part of them run in OpenStack? It would be great to use Cilium with CiliumNetworkPolicies to enforce the boundaries. This is all possible in k8s, but what happens if we use the same network layer also outside of k8s? What if each OpenStack cluster is connected with k8s clusters with Cilium and k8s clusters with Calico and form a clustermesh? Sounds crazy? It might not be as crazy as it sounds, thanks to Cilium.. this is possible. See for yourself.
