Lower administrative burden

Easy to use

You can use the AWS Management Console, the Amazon RDS Command Line Interface, or simple API calls to access the capabilities of a production-ready relational database in minutes.

Amazon RDS database instances are pre-configured with parameters and settings appropriate for the engine and class you have selected. You can launch a database instance and connect your application within minutes. DB Parameter Groups provide granular control and fine-tuning of your database.

Automatic software patching

Amazon RDS will make sure that the relational database software powering your deployment stays up-to-date with the latest patches. You can exert optional control over when and if your database instance is patched.

Best practice recommendations

Amazon RDS provide best practice guidance by analyzing configuration and usage metrics from your database instances. Recommendations cover areas such as database engine versions, storage, instance types, and networking. You can browse the available recommendations and perform a recommended action immediately, schedule it for their next maintenance window, or dismiss it entirely.

Performance

General Purpose (SSD) Storage

Amazon RDS General Purpose Storage is an SSD-backed storage option delivers a consistent baseline of 3 IOPS per provisioned GB and provides the ability to burst up to 3,000 IOPS. This storage type is suitable for a broad range of database workloads.

Provisioned IOPS (SSD) Storage

Amazon RDS Provisioned IOPS Storage is an SSD-backed storage option designed to deliver fast, predictable, and consistent I/O performance. You specify an IOPS rate when creating a database instance, and Amazon RDS provisions that IOPS rate for the lifetime of the database instance. This storage type is optimized for I/O-intensive transactional (OLTP) database workloads. You can provision up to 40,000 IOPS per database instance, although your actual realized IOPS may vary based on your database workload, instance type, and database engine choice.

Scalability

Push-button compute scaling

You can scale the compute and memory resources powering your deployment up or down, up to a maximum of 32 vCPUs and 244 GiB of RAM. Compute scaling operations typically complete in a few minutes.

Easy storage scaling

As your storage requirements grow, you can also provision additional storage. The Amazon Aurora engine will automatically grow the size of your database volume as your database storage needs grow, up to a maximum of 64 TB or a maximum you define. The MySQL, MariaDB, SQL Server, Oracle, and PostgreSQL engines allow you to scale up to 16 TB of storage on-the-fly with zero downtime.

Read Replicas

Read Replicas make it easy to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads. You can create one or more replicas of a given source DB instance and serve high-volume application read traffic from multiple copies of your data, thereby increasing aggregate read throughput. Read replicas are available in Amazon RDS for MySQL, MariaDB, and PostgreSQL as well as Amazon Aurora.

Availability and durability

Automated backups

The automated backup feature of Amazon RDS enables point-in-time recovery for your database instance. Amazon RDS will backup your database and transaction logs and store both for a user-specified retention period. This allows you to restore your database instance to any second during your retention period, up to the last five minutes. Your automatic backup retention period can be configured to up to thirty-five days.

Database snapshots

Database snapshots are user-initiated backups of your instance stored in Amazon S3 that are kept until you explicitly delete them. You can create a new instance from a database snapshots whenever you desire. Although database snapshots serve operationally as full backups, you are billed only for incremental storage use.

Multi-AZ deployments

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for database instances, making them a natural fit for production database workloads. When you provision a Multi-AZ database instance, Amazon RDS synchronously replicates your data to a standby instance in a different Availability Zone (AZ).

Automatic host replacement

Amazon RDS will automatically replace the compute instance powering your deployment in the event of a hardware failure.

Security

Encryption at rest and in transit

Amazon RDS allows you to encrypt your databases using keys you manage through AWS Key Management Service (KMS). On a database instance running with Amazon RDS encryption, data stored at rest in the underlying storage is encrypted, as are its automated backups, read replicas, and snapshots.

Amazon RDS supports Transparent Data Encryption in SQL Server and Oracle. Transparent Data Encryption in Oracle is integrated with AWS CloudHSM, which allows you to securely generate, store, and manage your cryptographic keys in single-tenant Hardware Security Module (HSM) appliances within the AWS cloud.

Amazon RDS supports the use of SSL to secure data in transit.

Network isolation

AWS recommends that you run your database instances in Amazon VPC, which allows you isolate your database in your own virtual network and connect to your on-premises IT infrastructure using industry-standard encrypted IPsec VPNs. You can configure firewall settings and control network access to your database instances.

Resource-level permissions

Amazon RDS is integrated with AWS Identity and Access Management (IAM) and provides you the ability to control the actions that your AWS IAM users and groups can take on specific Amazon RDS resources, from database instances through snapshots, parameter groups, and option groups. You can also tag your Amazon RDS resources and control the actions that your IAM users and groups can take on groups of resources that have the same tag and associated value. For example, you can configure your IAM rules to ensure developers are able to modify "Development" database instances, but only Database Administrators can make changes to "Production" database instances.

Manageability

Monitoring and metrics

Amazon RDS provides Amazon CloudWatch metrics for your database instances at no additional charge. You can use the RDS Management Console to view key operational metrics, including compute/memory/storage capacity utilization, I/O activity, and instance connections. Amazon RDS also provides Enhanced Monitoring, which provides access to over 50 CPU, memory, file system, and disk I/O metrics, and Performance Insights, an easy-to-use tool that helps you quickly detect performance problems.

Event notifications

Amazon RDS can notify you via email or SMS text message of database events through Amazon SNS. You can use the AWS Management Console or the Amazon RDS APIs to subscribe to over 40 different database events associated with your database instances.

Configuration governance

Amazon RDS integrates with AWS Config to support compliance and enhance security by recording and auditing changes to the configuration of your DB instance including parameter groups, subnet groups, snapshots, security groups and event subscriptions.

Cost-effectiveness

Pay only for what you use

There is no up-front commitment with Amazon RDS; you simply pay a monthly charge for each database instance that you launch. And, when you’re finished with a database instance, you can easily delete it. To see more details, visit the Amazon RDS Instance Types page and the Amazon RDS Pricing page.

Reserved instances

Amazon RDS Reserved Instances give you the option to reserve a DB instance for a one or three year term and in turn receive a significant discount compared to the On-Demand Instance pricing for the DB instance.

Stop and start

Amazon RDS allows you to easily stop and start your database instances for up to 7 days at a time. This makes it easy and affordable to use databases for development and test purposes, where the database is not required to be running all of the time.
