24 Caveat Emptor Everybody claims ETSI NFV MANO compliance Every NFV management product is really a rebranded legacy product with some adjustment for NFV MANO All integrations are custom, require time and thorough testing Not all products support multitenancy Not all virtual appliances are virtualization-friendly Hypervisors were not originally designed for NFV (basic functionality tweaking, performance tuning) 2017 NIL, Security Tag: INTERNAL 24

25 Main NFV Design Goals Adding a new service or modifying an existing services should not be rocket science Troubleshooting capabilities and tools should be available Re-instantiating a service instance should be available and simple Scaling of physical resources should be simple 2017 NIL, Security Tag: INTERNAL 25
