Grasping a first layout

Let's rekindle the flame and implement a basic architectural design. You probably have a running OpenStack environment where you have installed its different pieces across multiple and dedicated server roles. The architectural design of the OpenStack software itself gives you more flexibility to build your own private cloud. As mentioned in the first section, the loosely coupled design makes it easier to decide how to run services on nodes in your data center. Depending on how big it is, your hardware choices, or third-party vendor dependencies, OpenStack has been built so that it can't suffer from vendor lock-in. This makes it imperative that we do not stick to any specific design pattern or any vendor requirements.

The following figure shows a basic conceptual design for OpenStack deployment in a data center:
