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. The service level agreement for Amazon EC2 covers several compute services, including: So there are some important things you need to look for and take into account when trying to understand Amazon Web Services service level agreements. The most important advice I would offer is not to rely on service level agreements to guarantee the operating time of your applications. The ALS provides some guidance on the hours of operation you can expect, but the service credits offered, provided you remember to claim them, will likely be unlikely to compensate for the downtime your application is experiencing, and the likely business consequences in terms of lost productivity or even lost revenue. 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. 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: Service credits for S3 services (excluding those mentioned above) are as follows: In this article, we study SLAs for some of the most frequently 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 the actual SLAs for the services you want to use.
