A managed service is a provider-operated capability with defined operational responsibilities. For databases, the provider may handle the software, machines, operating system, updates, storage, replication, and backups, while you configure the service and control application access. section 10.0 section 12.10
Managed services reduce infrastructure work, but they do not remove every operational decision:
- Amazon RDS provides ready-to-use relational engines including PostgreSQL, MySQL, MariaDB, Oracle Database, Microsoft SQL Server, and Aurora. section 10.0
- DynamoDB removes installation, updates, machine, storage, and routine backup administration; you still monitor capacity, provision read and write capacity, restrict access with IAM, and configure recovery backups. section 12.10
WordPress database on Amazon RDS
A WordPress application can send requests through a load balancer to multiple web servers, while each server connects to a MySQL database on Amazon RDS. RDS handles operation of the relational database; the application team can then import, back up, restore, and later improve database availability and performance. section 10.0
