Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the AWS Cloud. It provides cost-efficient, resizable capacity for an industry-standard relational database and manages common database administration tasks.

Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups. It frees you to focus on your applications so you can give them the fast performance, high availability, security and compatibility they need.

Amazon RDS is available on several [database instance types] (optimized for memory, performance or I/O) and provides you with six familiar database engines to choose from, including [Amazon Aurora](https://aws.amazon.com/es/rds/aurora/), [PostgreSQL](https://aws.amazon.com/es/rds/postgresql/), [MySQL](https://aws.amazon.com/es/rds/mysql/), [MariaDB](https://aws.amazon.com/es/rds/mariadb/), [Oracle Database](https://aws.amazon.com/es/rds/oracle/) and [SQL Server](https://aws.amazon.com/es/rds/sqlserver/). You can use the [AWS Database Migration Service](https://aws.amazon.com/es/dms/) to easily migrate or replicate your existing databases to Amazon RDS.

<u>**Use cases**</u>

- **Web and mobile applications:** Web and mobile applications that are built to operate at very large scale need a database with high throughput, massive storage scalability, and high availability. Amazon RDS fulfills the needs of such highly demanding applications with room for future growth. Since Amazon RDS does not have any licensing constraints, it perfectly fits the variable usage pattern of these applications.
- **Ecommerce applications:** Amazon RDS offers small and large ecommerce businesses a flexible, secured, highly scalable, and low-cost database solution for online sales and retailing. Amazon RDS provides a managed database offering helping ecommerce companies meet PCI compliance and focus on building high quality customer experiences without worrying about managing the underlying database.
- **Mobile and online games:** Mobile and Online games need a database platform with high throughput and availability. Amazon RDS manages the database infrastructure so game developers don’t have to worry about provisioning, scaling, or monitoring database servers. Amazon RDS provides familiar database engines that can rapidly grow capacity to meet user demand.

<u>**Benefits**</u>

- **Easy to administer:** Amazon RDS makes it easy to go from project conception to deployment. Use the Amazon RDS Management Console, the AWS RDS Command-Line Interface, or simple API calls to access the capabilities of a production-ready relational database in minutes. No need for infrastructure provisioning, and no need for installing and maintaining database software.
- **Highly scalable:** You can scale your database's compute and storage resources with only a few mouse clicks or an API call, often with no downtime. Many Amazon RDS engine types allow you to launch one or more Read Replicas to offload read traffic from your primary database instance.
- **Available and durable:** Amazon RDS runs on the same highly reliable infrastructure used by other Amazon Web Services. When you provision a Multi-AZ DB Instance, Amazon RDS synchronously replicates the data to a standby instance in a different Availability Zone (AZ). Amazon RDS has many other features that enhance reliability for critical production databases, including automated backups, database snapshots, and automatic host replacement.
- **Fast:** Amazon RDS supports the most demanding database applications. You can choose between two SSD-backed storage options: one optimized for high-performance OLTP applications, and the other for cost-effective general-purpose use. In addition, Amazon Aurora provides performance on par with commercial databases at 1/10th the cost.
- **Secure:** Amazon RDS makes it easy to control network access to your database. Amazon RDS also lets you run your database instances in Amazon Virtual Private Cloud (Amazon VPC), which enables you to isolate your database instances and to connect to your existing IT infrastructure through an industry-standard encrypted IPsec VPN. Many Amazon RDS engine types offer encryption at rest and encryption in transit.
- **Inexpensive:** You pay very low rates and only for the resources you actually consume. In addition, you benefit from the option of On-Demand pricing with no up-front or long-term commitments, or even lower hourly rates via our Reserved Instance pricing.
