==Management and orchestration (MANO)==

[[ETSI]] has already indicated that an important part of controlling the NFV environment be done through automation andautomated orchestration.

ETSI delivers a full set of standards '''enabling an open ecosystem''' where Virtualized Network Functions (VNFs) can be interoperable with independently developed management and orchestration systems, and where the components of a management and orchestration system are themselves interoperable. This includes a set of [[Representational state transfer|Restful API]] specifications<ref>{{Cite journal|last=Chatras|first=B.|date=December 2018|title=On the Standardization of NFV Management and Orchestration APIs|journal= IEEE Communications Standards Magazine|volume=2|issue=4|pages=66–71|doi=10.1109/MCOMSTD.2018.1800032|s2cid=59620488|issn=2471-2825}}</ref> as well as the specifications of a packaging format for delivering VNFs to service providers and of the deployment templates to be packaged with the software images to enable managing the lifecycle of VNFs. Deployment templates can be based on [[OASIS TOSCA|TOSCA]] or [[YANG]].<ref>{{Cite web|url=https://www.etsi.org/newsroom/press-releases/1540-2019-01-etsi-releases-a-standard-for-nfv-deployment-templates|title=ETSI - ETSI releases a standard for NFV Deployment Templates|last=ETSI COMS TEAM|website=ETSI|access-date=2019-07-09}}</ref><ref>{{Cite web|url=https://www.etsi.org/newsroom/blogs/entry/sol006-nfv-descriptors-based-on-yang-specification|title=Technology blogs, NFV, MEC, NGP, ZSM, ENI - SOL006 – NFV descriptors based on YANG Specification|website=www.etsi.org|access-date=2019-07-09}}</ref>
