OpenStack out of the box does KVM, network, firewalls, NVFs, orchestration (via native heat or terraform), and with the Magnum component can launch k8s, Mesos, or Swarm largely automagically. Storage is typically via ceph (which does block, object [supports Swift/S3 protocols] and filesystem) and supports snapshots and is fully replicated. Sadly the managed database service didn't make it far, but with Heat or Terraform it's pretty easy to spin up a VM holding your DBs. The native FaaS service, Qinling got deprecated a while back. Secrets management via the barbican component. Web interface via the horizon component.
I'm not too familiar with the whole range of AWS offerings, but I really think aside for DBaaS and FaaS OpenStack can cover pretty much everything someone would need, especially combined with Ceph for storage.
Yes, I'm aware. It doesn't reduce or negate the need for a team responsible for running storage and understanding how it works, then a team owning databases (probably with some development resources too) and so on.
It actually takes work to setup and run we are not just installing some packages and then pretending you can scrap aws.

All opensource.
