It's a bit scary that Amazon AWS is the only complete solution in this space now.

There are so many open projects in the cloud space that one would think it's a solved problem.

Here's a list off the top of my head:

1. Docker - Container implementation.

2. Kubernets - Manage a cluster of Linux containers.

3. Mesos - Manage a cluster of resources (not just containers, I'm guessing there are some feature overlap with Kubernets).

4. CoreOS - An OS specialized in running containers.

5. RethinkDB, CouchDB, Cassandra - Distributed databases

6. Ceph, GlusterFS - Distributed file systems

7. RabbitMQ, NSQ, NATS - Distributed queue systems.

8. Manage VM's in a Data center ?? - I don't know any projects in this space.

What's missing is an interface to manage all these together. Maybe this is the direction OpenStack should be heading?
