Dear Team
After reading through below Tutorial, I have some questions regarding Database and NoSQL setup model for Federated User Location Cluster.


For example, for formal production system senario, two sites, with two opensips nodes for each site, HA mode for each site.
1. Should I deploy MySQL and Cassandra on each node? 4 MySQL instances and 4 Cassandra on each node?
2. Should I setup db replication among 4 MySQL instances or just standalone separated setup?
3. Should I put all 4  Cassandra instances into one cluster?
4. For each HA virtual IP setup, what's the recommended tool, keepalived?

Thanks in advance.

Best wishes,
