Persist Network
Network persistence maintains the public IP and private IP for the virtual machine.

Example Use Cases
Customers who manage their workloads based on IP addresses. Migrating existing services without having to change the configurations. NoSQL databases (for example, Cassandra, Scylla, Mongo) that require a fixed set of Private IPs.
Persist Network for Stateful Node
