Explanation:
When you want a self-managed database with complete control over both the database engine and the underlying infrastructure, you need to host the database on an EC2 Instance. This is because:
-
Amazon RDS is a managed database service where AWS handles infrastructure management, patching, and backups
-
Amazon DynamoDB is a fully managed NoSQL database service
-
Amazon Aurora is a managed relational database service compatible with MySQL and PostgreSQL
-
Amazon EC2 provides virtual servers where you have full control over the operating system, database software, and all configurations
With EC2 instances, you are responsible for:
-
Installing and configuring the database software
-
Managing database backups and recovery
-
Applying security patches and updates
-
Scaling the infrastructure as needed
-
Monitoring performance and availability
This self-managed approach gives you maximum flexibility but also requires more operational overhead compared to managed database services.
