Now, the tasks performed by Amazon ECS and AWS Fargate are covered by Amazon Compute-SLA with a 99.99% commitment to service availability and availability. If you do not comply with this obligation, you will receive a service credit. The SLA operating time varies depending on the type of S3 service and the guaranteed operating time varies from 99.9% to 99%. AWS has issued a Service Level Agreement (SLA) for AWS Systems Manager, which offers availability guarantees for AWS Systems Manager. For EC2 (and associated services), the credits available are: All S3 services have a guaranteed operating life of 99.9%, with the exception of the following services, which are guaranteed for 99% of the operating time: AWS offers service credits for non-compliance with the ALS of 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 more information on AWS regions and services, click here. AWS provides all the tools and services you need to create a resilient, 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 respect the principles of AWS Well Architected, and that you respect your responsibilities in 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. The service credits for S3 services (excluding the ones mentioned above) are as follows: So you have a few important things 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. It`s also important to make sure your application infrastructure is observable – if you don`t recognize service outages, you can`t make claims against the ALA, so you can no longer get credits. You need to be able to back up your rights with log files, so make sure you know where to get them! The service level agreement for Amazon EC2 covers several compute services, including: AWS Support Response Time are separated from each service-Uptime-SLAs.
