Aws Service Level Agreement

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. The service credits available for S3 services (except those listed above) are as follows: AWS provides all tools and services, You need 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 response model. AWS Shared: For CE2 (and related services), available credits are as follows: Availability SLA varies by S3 service type, and guaranteed uptime ranges from 99.9% to 99%. 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. The service level agreement for Amazon EC2 includes several compute services, including: In this article, we study 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 is being offered, but this is only a guide and should not be considered a substitute for reading the actual AIS for the services, that you want to use. It`s also important to make sure you have good observability of your application infrastructure – if you don`t recognize service outages, you can`t assert claims against ALS, so you risk missing credits. You need to be able to back up your claims with log files – so make sure you know where to get them! So here you have some important things to keep in mind and keep in mind when trying to understand Amazon service agreements. The most important advice I would give is not to rely on service level agreements to ensure the availability of your applications. The SLA provides some instructions on the hours of operation you can expect, but the service credits offered, provided you`re thinking about using them, probably won`t do much to remove the downtime from your application and the likely business consequences in terms of lost productivity or maybe even lost revenue…
