Amazon RDS (Amazon Relational Database Service) is a managed service that makes it simple to set up, run, and scale a relational database on the web. It provides scalable and cost-effective capacity while handling time-consuming database administration responsibilities, freeing you to concentrate on your applications and company.

A MySQL, MariaDB, Oracle, SQL Server, or PostgreSQL database can be accessed using Amazon RDS. This means that any code, programs, or tools you’ve used with other databases should work with Amazon RDS as well.

Amazon RDS can back up and update your database using the most recent version of the database software. You get the benefit of being able to simply scale your relational database instance’s computing resources and storage capacity.

Furthermore, for read-intensive database workloads, Amazon RDS makes replication simple to improve database availability, data durability, or scale beyond the capacity constraints of a single database instance. There are no upfront expenses; instead, like with other Amazon Web Services, you only pay for the resources you use.

When should you utilize RDS?

From procuring the infrastructure capacity you request to installing the database software, Amazon RDS manages the labour involved in setting up a relational database. Amazon RDS automates typical administration activities like as backups and patching the software that powers your database once it’s up and running. Amazon RDS also manages synchronous data replication between Availability Zones with automated failover in Multi-AZ installations.

For developers, Amazon Web Services offers a variety of database options. Amazon RDS allows you to run a relational database with all of its features while offloading database administration. You may administer your own relational database in the cloud by using one of our many relational database AMIs on Amazon EC2.

Features

• Improved Monitoring: Amazon RDS offers a variety of options for automating a variety of DBA tasks, as well as a variety of features for performing extensive system performance monitoring.
• AWS Database Migration Service (DMS): DMS can assist you in migrating to the cloud with virtually no downtime, allowing you to benefit from the scalability, operational efficiency, and variety of data storage options available.
• Multiple Availability Zones (Multi-AZ) RDS Deployments: AWS RDS will automatically switch from the primary instance to the available standby replica in the event of a failure, in the event of a planned interruption, such as software patching or changing the RDS instance type, such as an Availability Zone outage, internal hardware or network outage, or a software failure; or in the event of an Availability Zone outage, internal hardware or network outage, or a software failure. 
• Encryption of Amazon RDS Resources: All data on the instance’s underlying storage, automated backups, read replicas, and snapshots are encrypted when RDS encryption is enabled. The RDS encryption keys use the AES-256 technique, which is exclusively handled and safeguarded by the AWS key management infrastructure via the AWS Key Management Service (AWS KMS).
• Amazon RDS Cross-Region Read Replicas: For database (DB) instances, Amazon RDS Read Replicas improve performance and durability. For read-only applications, cross-region read replicas can provide significant performance gains for users in several areas.
