Common use cases
Replication is useful when you need a standby database, a read-only replica for reporting, or a cleaner path to high availability. It also helps when backups are too slow to be your only recovery option.
- Primary-to-replica MySQL or MariaDB setup
- Binary log, GTID, and replication health review
- Failover and promotion planning
- Read scaling for reporting workloads
- Monitoring, lag checks, and troubleshooting
What gets validated
A usable replication design includes credentials, network access, log retention, backup strategy, and a tested recovery path. The goal is to make the replica useful instead of merely present.
When this is worth doing
This service makes sense when the database is business-critical, writes are steady, downtime is expensive, or you need a controlled way to separate reads from writes.
