Amazon Relational Database Service (Amazon RDS)

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.

Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle, Microsoft SQL Server, or PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call.

Amazon RDS DB Instances can be provisioned with either standard storage or Provisioned IOPS storage. Amazon RDS Provisioned IOPS is a storage option designed to deliver fast, predictable, and consistent I/O performance, and is optimized for I/O-intensive, transactional (OLTP) database workloads.

In addition, Amazon RDS makes it easy to use replication to enhance availability and reliability for production workloads. Using the Multi-AZ deployment option you can run mission critical workloads with high availability and built-in automated fail-over from your primary database to a synchronously replicated secondary database in case of a failure. Amazon RDS for MySQL also enables you to scale out beyond the capacity of a single database deployment for read-heavy database workloads. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.

Simple to Deploy Database Web ServiceAmazon RDS makes it easy to go from project conception to deployment. Use the AWS Management Console  or simple API calls to access the capabilities of a production-ready relational database in minutes without worrying about infrastructure provisioning or installing and maintaining database software.

ManagedAmazon RDS handles time-consuming database management tasks, such as backups, patch management, and replication, allowing you to pursue higher value application development or database refinements.

CompatibleWith Amazon RDS, you get native access to a relational database. This facilitates compatibility with your existing tools and applications. In addition, Amazon RDS gives you optional control over which supported MySQL DB Engine Version or Oracle DB Engine Version powers your DB Instance via DB Engine Version Management.

Fast, Predictable PerformanceAmazon RDS Provisioned IOPS is a high performance storage option designed to deliver fast, predictable, and consistent performance for I/O intensive transactional database workloads. You can provision from 1,000 IOPS to 30,000 IOPS per DB Instance. Note that maximum realized IOPS will vary by engine type.

Scalable Database in the CloudYou can scale the compute and storage resources available to your database to meet your application needs using the Amazon RDS API or the AWS Management Console. If you are using Amazon RDS Provisioned IOPS storage with Amazon RDS for MySQL, Oracle, or PostgreSQL, you can provision and scale the storage up to 3TB and IOPS to up to 30,000. Note that maximum realized IOPS will vary by engine type. In addition,

for the MySQL database engine, you can also associate one or more Read Replicas with your database instance deployment, enabling you to scale beyond the capacity of a single database instance for read-heavy workloads.

ReliableAmazon RDS has multiple features that enhance reliability for critical production databases, including automated backups, DB snapshots, automatic host replacement, and Multi-AZ deployments for the MySQL,  Oracle, and PostgreSQL database engines. Amazon RDS runs on the same highly reliable infrastructure used by other Amazon Web Services.

Designed for use with other Amazon Web ServicesAmazon RDS is tightly integrated with other Amazon Web Services. For example, an application running in Amazon EC2 will experience low-latency database access to an Amazon RDS DB Instance in the same region.

SecureAmazon RDS provides a number of mechanisms to secure your DB Instances.

● Amazon RDS includes web service interfaces to configure firewall settings that control network access to your database.

● Amazon RDS allows you to run your DB Instances in Amazon Virtual Private Cloud (Amazon VPC). Amazon VPC enables you to isolate your DB Instances by specifying the IP range you wish to use, and connect to your existing IT infrastructure through industry-standard encrypted IPsec VPN. To learn more about Amazon RDS in VPC, refer to the Amazon RDS User Guide .

InexpensiveYou 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 pricing option.

● On-Demand DB Instances – On-Demand DB Instances let you pay for compute capacity by the hour with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs.

● Reserved DB Instances – Reserved DB Instances give you the option to make a low, one-time payment for each DB Instance you want to reserve and in turn receive a significant discount on the hourly usage charge for that DB Instance. Depending on your usage, you can choose between three Reserved DB Instance types (Light, Medium, and Heavy Utilization) and receive anywhere between 30% and 55% of discount over On-Demand prices.
