Present and future of Ceph integration with OpenStack and k8s

OpenStack and Ceph have a long integration story that changed over the time to make the two technologies coexist in the same context as basic building blocks of Cloud infrastructures. ceph-ansible has been one of the most popular orchestrators for Ceph, but cephadm and the Ceph orchestrator have been a game changing in the way how operators interact with Ceph. To streamline the deployment process, OpenStack services need to be configured to interact with Ceph but there is also a need to bootstrap, configure and tune the Ceph cluster to meet the OpenStack workload. An example is Manila, where the new ceph mgr interface enabled new drivers and simplified the existing use cases. This talk will give an overview of the current state of the integration, and how projects in the OpenStack ecosystem changed and updated the reference architecture as a result of the introduction of cephadm and the Ceph orchestrator but also look towards at the Kubernetes integration, when a single Ceph cluster can be shared by OpenStack (rbd interface) and the Kubernetes workloads via pvc.
