Executed by assigning each project its own VLAN and an internal and external IP address pool.Once the hardware and network are set up, the next step is to determine where all the OpenStack components are deployed. Standard deployments should have a controller and a series of compute nodes. The controller runs the message server, the database, and other components to orchestrate the cloud whi
