OpenStack Basic Design Tenetshttp://wiki.openstack.org/BasicDesignTenets
1. Scalabilityandelasticityare our main goals
2. Any feature that limits our main goals must be optional
3. Everything should be asynchronous. If you can't do something asynchronously, see #2
4. All required components must be horizontally scalable
5. Always use Shared Nothing architectureorShardingIf you can't Share Nothing/Shard, see #2
6. Distribute everything, especially logic. Move logic to where state naturally exists.
7. Accept eventual consistency and use it where it is appropriate.
8. Test everything.We require tests with submitted code.
