MySQL

Use MySQL clusters for managed primary/replica deployments with DNS endpoints, security groups, parameter groups, and backups.

How it works

1. Create a cluster and wait until Status is Ready.
2. Open TCP port 3306 on the attached security group for your client CIDR.
3. Connect with the read/write domain as user root.
4. (Optional) Add replicas, run switchover, or configure backups.

Endpoints

• Read/write domain — current primary
• Read-only domain — replicas (same host as primary when no replica exists)
