You can install your own S3 compatible storage system on premises. It can be anything from a simple daemon (Scality, JuiceFS) to a small appliance (TrueNAS) to a full-blown storage cluster (Ceph). OpenStack has it own object storage service (Swift).

If you fancy it for your datacenter, big players (Fujitsu, Lenovo, Huawei, HPE) will happily sell you "object storage" systems which also support S3 at very high speeds.

And for CI and local development testing you can use localstack which runs in a docker container and has implementations of most AWS services

		Oh, that sounds interesting. We don't use AWS, but it's a nice alternative for people using AWS for their underpinnings. Scality's open source S3 Server also can run in a container.
