Network Functions Virtualization (NFV) is a network architecture concept using technologies of IT virtualization to virtualize entire classes of network node functions. The node functions are changed into building blocks that may connect or linked together to create communication service.

MANO is a technology for deploying NFV. Open source technology is
disrupting the telecom sector for building 5G internet powered by NFV and
SDN (Software Defined Networking). Open Source Technologies have
transformed the application development process that has led to digital
transformation across various industry verticals.

3. Overview of MANO
The management and orchestration (MANO) layer is concerned with the
orchestration and complete lifecycle management of hardware
resources and virtual network functions. It integrates NFV infrastructure
resources and maps them efficiently to various VNFs.
The ETSI hosted Open Source Mano (OSM) is primarily preferred due to
its scale of activity at the community level, highly mature framework,
production readiness, ease of initiation and constant use feedings by
members. OSM offers cloud readiness involvement which is critical for
lean NFV infrastructure.

The Mano layer works with templates for standard VNFs and enables users to
pick and choose from existing NFVI resources to deploy their platform. MANO
framework has three functional blocks
