This Amazon Compute Service Level Agreement (”SLA”) is a policy for the use of included services (below) and applies separately to each account that uses the services contained. In the event of a conflict between the terms and conditions of this ALS and the terms of the AWS customer agreement or any other agreement with us regarding your use of our services (the ”Contract”), the terms of this ALS apply, but only to the extent of such a conflict. The terms used in this agreement, but which are not defined here, have the meaning of the agreement. AWS has issued a Service Level Agreement (SLA) for AWS Systems Manager, which offers availability guarantees for AWS Systems Manager. For all RDS areas hosted in multiple availability areas (the ”Multi AZ” setting is defined as ”True”), Amazon guarantees 99.5% operating time on each monthly billing cycle. This allows up to 3.65 hours of downtime per month. For applications that cannot tolerate downtime, customers should consider hosting their databases in multiple regions or using another database service, such as Amazon Aurora, which has an ALS with a 99.99% operating time. AWS offers service credits for non-compliance with the ALS operating time, but it is important to note that they are not applied automatically. To obtain service credits for downtime, AWS customers must assert a right to credit by opening a business in the AWS assistance centre with the words ”SLA credit requirement” in the subject line and specifying the details of the dates and times of defaults or failures for which you use secure credits with protocols and resource IDs for the services concerned. If service credits are available for loss, they are normally used as credit on future invoices for the same service. For EC2 (and related services), the credits available are: AWS provides all the tools and services you need to create a strong, highly available and highly secure cloud infrastructure, but it`s up to you, as a customer, to ensure that best practices are followed, that you adhere to the principles of AWS Well Architected and that you meet your responsibilities under the AWS shared responsibility model. : In this article, we look at SLAs for some of the most commonly used AWS services, including EC2, RDS, EBS, ECS, Fargate and S3, to give you a taste of the offer, but this is only a guide and should not be considered a substitute for reading real SLAs for the services you want to use.
All S3 services have a guaranteed operating life of 99.9%, with the exception of the following services, which are guaranteed for 99% of operating time: The Service Level Agreement for Amazon EC2 covers several compute services, including: Service credits available for S3 services (excluding the services listed above) are as follows: It is also important to ensure that you are well monitored by your application infrastructure – if you do not recognize the service outages you do can`t make claims against ALS, so you might miss out on credits.
