Look at the cost of moving out of the cloud carefully. Can you afford the up-front costs of the hardware needed to run the solutions you may want to run? Will those solutions have good enough data locality to be useful to you? It isn't real useful to have all your data on-site, and then you operations in the cloud. You've introduced many new layers that can fail. If you go on-prem, the solution to look at is likely Ceph. Source: Storage Software Engineer, who has spoken at SNIA SDC. I currently maintain a "small" 1PB ceph cluster at work. Recommendation: Get someone who knows storage and systems engineering to work with you on the project. Even if you decide not to move, understanding why is the most important part.
