## Hardware requirements & design

<https://docs.openstack.org/newton/install-guide-rdo/overview.html#example-architecture\\>
at least two nodes (hosts):controller(2 NICs) + compute(2 NICs)\
Optional services such as Block Storage and Object Storage require additional nodes.

## devstack

<http://docs.openstack.org/developer/devstack/guides/single-machine.html\\>
Use of postgresql in devstack is deprecated, and will be removed during the Pike cycle
