We're running Ceph with Rook and Minio in Kubernetes. I'm evaluating Garage as an alternative for some purposes such as application instance static files for Python or Javascript applications to avoid block volumes in deployments. Garage has a simpler high availability distribution story than Minio's erasure coding striping, but it works well for applications that don't require sub-second writes. It can do high availability with only three nodes versus four for Minio, which works well for smaller setups. It can also serve static websites straight from a bucket, which would work well for static sites like those made with static site generators.

Ceph has an S3 API gateway, but it's a more wholesome solution better suited for larger setups compared to Minio and Garage.
