Service base architecture of 5g core Network will support virtualization deployment. In SBA network can be deployed as fully distributed, fully redundant, stateless, and fully scalable. Within a same network set, many Network Instances can be present. With this virtualization, services can be provided from anywhere.
Consider an example of UDR set. When a UE invoke a UDR services like registration, this virtualization will help to route the request to any UDR within the set of UDRs
This will also help to turn off any specific instance of UDR for planned maintenance. There will also be UDR auto-recovery feature without any service disruption.
