OpenStack Networking

Cloud-based solutions are being adopted at an increasing rate by businesses for their IT driven needs. This move to cloud started with the server virtualization where a hardware server ran as a virtual machine on a hypervisor.

The server hardware connects to the Network switches using Ethernet and IP to establish Network connectivity. However, as servers move from physical to virtual, the Network boundary also moves from the physical network to the virtual network. As the cloud platforms leverage virtualization, it becomes more important that they support the physical and virtual networking effectively.

OpenStack is an open source cloud platform that helps build public and private clouds at scale. The OpenStack networking core functionality refers to the Layer 2 Network connectivity and basic IP address management for virtual machines.

The functions of OpenStack itself can only be handled by using some king of abstraction interface that humans can interact with. This is accomplished by using an OpenStack Orchestration program like Heat commonly used by Amazon's AWS Cloud to create the human and machine interface.
