Amazon Rds Service Level Agreement

Amazon RDS Service Level Agreement: What You Need to Know

Amazon RDS, or Amazon Relational Database Service, is a database management system (DBMS) offered by Amazon Web Services (AWS) that provides a scalable and highly available platform for hosting and managing relational databases. As with any cloud-based service, Amazon RDS comes with a service level agreement (SLA) that outlines the terms and conditions of the service, including uptime guarantees, performance metrics, and other important details.

Here`s what you need to know about the Amazon RDS SLA and what it means for your business.

Uptime Guarantee

One of the most important aspects of any cloud-based service is uptime, or the amount of time that the service is available and functioning properly. With Amazon RDS, AWS guarantees a monthly uptime percentage of at least 99.95%. If AWS fails to meet this uptime guarantee, customers may be eligible for service credits based on the extent of the outage.

Performance Metrics

In addition to uptime guarantees, the Amazon RDS SLA also outlines several performance metrics that customers can use to monitor the health and performance of their databases. These metrics include:

– CPU Utilization: The percentage of CPU usage by the database instance over a given period of time.

– Average Latency: The average time it takes for a query to be processed by the database instance.

– Read and Write I/O Operations: The number of read and write operations performed by the database instance over a given period of time.

– Network Throughput: The amount of data transferred in and out of the database instance over a given period of time.

AWS provides customers with access to these metrics through the Amazon RDS console, allowing them to monitor their database performance in real-time and make adjustments as needed to optimize performance and reduce downtime.

Support and Maintenance

The Amazon RDS SLA also covers AWS support and maintenance policies, including the types of support and maintenance activities that customers can expect from AWS, as well as any downtime required for these activities. AWS generally performs maintenance activities during periods of low usage to minimize downtime and disruption to customers.


In summary, the Amazon RDS SLA provides customers with a guarantee of high uptime, as well as important performance metrics and support and maintenance policies. By understanding the implications of the SLA, customers can ensure that they are getting the most out of their Amazon RDS service and that they are able to respond quickly to any issues or outages that may occur. So, if you`re considering using Amazon RDS for your business, be sure to familiarize yourself with the SLA and what it means for you.
