Managing VNFs and VDUs in a network service

After deploying a network service, you can manage VNFs and VDUs (Virtual Deployment Units) included in them.

A VDU is a virtual machine that hosts a VNF. It aggregates virtual computing resources, such as CPU and memory, required to run the VNF software, and also contains certain implementations of the network function, such as routing algorithms or load balancing logic.

Multiple VDUs can be combined into a single VNF to provide scalability and/or high availability. VDUs can be distributed across multiple physical servers; you can still manage them as a single VNF. VDUs interact with each other and other VNFs to perform their functions within a network service.
