The SLA operating time varies depending on the type of S3 service and the guaranteed operating time varies from 99.9% to 99%. So you need to consider some important things when trying to understand Amazon`s 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. For EC2 (and related services), the credits available are: This Amazon S3 (SLA) service level agreement is a policy of using Amazon S3 and Amazon S3 Glacier (each an “Amazon S3 Service” under the terms of the Amazon Web Services customer contract (the AWS agreement) between Amazon Web Services, Inc. and its affiliates (“AWS,” “us” or “us”) and AWS users (“you”). This ALS applies separately to each account using an Amazon S3 service. Unless otherwise stated, this SLA is subject to the terms of the AWS agreement and the conditions activated have the meaning defined in the AWS agreement. We reserve the right to amend the terms of this ALS in accordance with the AWS agreement. AWS support response times are separated from each SERVICE-Uptime-SLAs. Response times vary between the 3 AWS support plans available – developers, businesses and businesses. To facilitate the comparison, I have listed the available response times and associated support costs in the table below.
Don`t expect a 15-minute support response if you only pay for a business support plan! Although, in my experience, AWS support is both fast and effective. If, in your billing cycle, you paid $100 for a standard S3 AI memory and the total operating time of the service (in this billing cycle) is %98, you will receive a $25 credit to use in AWS services. Does this mean that if the operating time of a certain service class, say S3 Standard-Infrequent Access, is less than 99.0%, but greater or equal to 95.0% in a given month, we will open a ticket and Amazon will compensate us at 25%? 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. Service credits for S3 services (excluding the services listed above) are as follows: In this article, we study 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 the actual SLAs for the services you wish to use. This Amazon S3 Service Level Agreement (“SLA”) is a policy of using Amazon S3 and Amazon S3 Glacier (an “Amazon S3 Service” each) and applies separately to each account using an Amazon S3 service. 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.
