OpenStack for NFV

As we know, OpenStack is mainly known to be the largest pool of open source projects which collectively forms the software platform for cloud computing infrastructure. This infrastructure is used widely in private cloud use cases by many enterprises. After an introduction of NFV by ETSI, OpenStack has emerged as a key infrastructure platform for NFV. In most of the NFV deployments, OpenStack is used at VIM the (Virtual Infrastructure Manager) layer to give a standardized interface for managing, monitoring and assessing all resources within NFV infrastructure.

Various OpenStack projects (like Tacker, Neutron, Nova, Astara, Congress, Mistral, Senlin, etc.) are capable of managing virtualized infrastructure components of NFV environment. As an example, Tacker is utilized to build generic VNF Manager (VNFM) and NFV Orchestrator (NFVO) which helps in the deployment and operation of VNFs within NFV infrastructure. Additionally, integration of OpenStack projects introduces various features to NFV infrastructure. Features include performance features like huge pages, CPU Pinning, NUMA topology and SR-IOV; service function chaining, networking slicing, scalability, high availability, resiliency and multisite enablement.
