Features of Amazon RDS include the following:

Replication. To build read copies, RDS makes advantage of the Replication capability. Applications employ these read-only replicas of database instances rather than the genuine production databases themselves. Additionally, administrators can use synchronous data replication and RDS Multi-AZ deployment to provide automatic failover across various availability zones.

Storage. RDS provides three types of storage:

  • A multifunctional solid-state drive (SSD). This storage is what Amazon suggests as the default option.
  • Provisioned operations per second for input-output (IOPS). SSD storage for workloads requiring lots of I/O.
  • Magnetic. A less expensive choice.
  • Monitoring. The managed monitoring feature of the Amazon CloudWatch service. It enables users to view I/O and capacity measurements.

Patching. Whichever database engine the user selects, RDS offers fixes.

Backups. Failure detection and recovery is another aspect. To provide point-in-time recovery, RDS offers controlled instance backups with transaction logs. Databases can be restored at any point in time during the user-selected retention period. Additionally, until they are explicitly destroyed, they can manually take snapshots of instances that are still running.

Progressive billing. A monthly cost is paid by users for the instances they start.

Encryption. RDS secures automated backups, read replicas, data snapshots, and other at-rest data using public key encryption.
