Orchestration & NFV
MANO, NSO & Service Orchestration
How SOM integrates with ETSI MANO and Cisco NSO for VNF/CNF lifecycle management and network service orchestration, including Day-0/1/2 responsibilities and RFS-to-engine mapping.

MANO vs Cisco NSO: What's the Difference?
Comparing ETSI MANO, Cisco NSO, and SOM — what each does, where they overlap, and when to use which.
The MANO Domain: SOM + MANO + NFVI
Deep dive into the MANO architecture: NFVO, VNFM, VIM layers, Day-0/1/2 lifecycle, and how SOM orchestrates above MANO.
SOM + Itential + NSO: The Three-Layer Stack
How Itential fits between SOM and NSO as the automation middleware — SOM decides what, Itential decides how, NSO safely changes the network — with L3VPN worked example and comparison to direct SOM→NSO integration.
NFVI: Network Functions Virtualisation Infrastructure
Brief overview of NFVI — the virtualised infrastructure layer that hosts VNFs and CNFs. Covers the role of VIM, compute/storage/networking resources, Gen 1 (OpenStack) vs Gen 2 (Kubernetes), and where NFVI fits in the telco stack relative to MANO, SOM, and ROM.
