Custom DBs

Custom DBs provide managed database automation while retaining full root-level access to the underlying operating system and database environment.

Custom DBs bridge the gap between fully managed services and self-managed instances. By using platforms like AWS RDS Custom, operators automate time-consuming tasks (patching, backups, and scaling) while maintaining the control required for legacy applications. This setup supports specific customizations like Oracle GoldenGate installations or specialized kernel settings that standard managed services block. It is the tactical choice for teams running enterprise workloads (ERP or CRM systems) that demand precise configuration alongside cloud-native durability.
