- Managed Oracle and Microsoft SQL Server with full OS and DB customization.
- AWS still handles provisioning, backups, scaling, but you have full administrative access.
- Allows:
- OS and DB configuration changes
- Installing patches or drivers
- Enabling native database features
- Connecting directly via SSH or SSM Session Manager
- To customize, disable Automation Mode (snapshot recommended before changes).
RDS vs RDS Custom
- RDS → Fully managed, no OS/DB access, AWS controls everything.
- RDS Custom → Same managed benefits, but you control the OS and DB.
