Service Level Agreement Amazon Web Services


For EC2 (and related services), the available credits are as follows: The service credits available for S3 services (with the exception of the services listed above) are as follows: The service level agreement for Amazon EC2 includes several compute services, including: It is also important to ensure that you have good observability of your application infrastructure – if you do not recognize service defects, you can`t make claims against ALS, so you risk missing out on credits. You need to be able to back up your claims with log files – so make sure you know where to get them! In this article, we look at SLAs for some of the most widely used AWS services, including EC2, RDS, EBS, ECS, Fargate, and S3, to give you an idea of what`s on offer, but it`s just a guide and shouldn`t be considered a substitute for reading the actual ISS for the services you want to use. AWS provides all the tools and services you need to build a robust, 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 AWS Well Architected principles, and that you fulfill your responsibilities under the AWS Shareds Responty model: This Amazon Compute Service Level Agreement (SLA) is a guideline, which regulates the use of the Included Services (see below) and applies separately to each account using the Included Services. In the event of any conflict between the terms of this SLA and the terms of the AWS Customer Agreement or any other agreement with us that governs your use of our services (the “Agreement”), the terms of this SLA apply, but only to the extent of such conflict. The wholesale terms used there, but not defined here, have the meaning defined in the agreement. For all RDS instances hosted in multiple Availability Zones (with the “Multi AZ” setting set to “True”), Amazon guarantees 99.5% availability on each monthly billing cycle. This allows up to 3.65 hours of downtime per month. For applications that cannot tolerate this downtime, customers should consider hosting their databases in multiple regions or using another database service like Amazon Aurora, which has a 99.99% SLA. AWS Support Response times are separated from each SLAs for service availability.

Response time varies between the 3 available AWS support plans – Developer, Business, and Enterprise. To simplify the comparison, I`ve listed the available response times and related support costs in the table below. Don`t expect a 15-minute support response if you`re only paying for a business support plan! Although, in my experience, aws-support is both fast and efficient. AWS offers service credits for non-compliance with the availability SLA, but it is important to note that they are not automatically applied. To earn service credits for downtime, AWS customers must assert a credit entitlement by opening a file at the AWS Help Center with the words “Credit Request SLA” in the subject line and providing details about the dates and times of default or default for which you are claiming credit. secured by protocols and resource identifiers for the relevant services. When service credits are available for the outage, they are normally used as a credit on future invoices for the same service. So here, you have a few important things to consider and keep in mind when trying to understand Amazon service agreements…
