Past, present and future of the storage in the CERN private cloud

Since the begining of the CERN private cloud solution back in 2012, CERN is running a different storage solutions to cover our user's needs. Starting with a reduced offering just with block devices with 2 different vendors, to offer now also fileshares and object store using many Ceph clusters. We'll show the issues we had on the storage area, how we overcome them and how we managed to evolve the setup to meet our user needs. One of the last additions was the inclusion of multiple availability zones on an existing live setup with no prior availability zone configured. This was done keeping the user workloads active and running. But the story doesn't end here, we are heavily investing in technologies like volume replication, share replication and multisite object integration.
