Aws Compute Service Level Agreement

For all our current services, we offer customers a monthly operating guarantee of at least 99.99%. If Fuga Cloud does not comply with ALS and the customer has complied with the terms of use and ALS, the customer is entitled to a financial credit. The SLA operating time varies depending on the type of S3 service and the guaranteed operating time varies from 99.9% to 99%. Planned maintenance is excluded from availability calculations, unless the expected maintenance time is exceeded and the hosting service is therefore not available to the customer. 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. So there are important things you need to look for and consider 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! To be entitled to financial compensation, the client must inform the Fuga support team within 30 days of the service`s downtime with the requirement for financial compensation.

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. The service level agreement for Amazon EC2 includes several compute services, including: For EC2 (and related services), the credits available are: Scheduled maintenance during our maintenance window. The customer is informed at least 14 days in advance by email to the registered email address. It is possible that, during this maintenance period, services may be temporarily out of service in whole or in part and are therefore not available to the customer. 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: in this case, we must multiply the availability target of each service.

The following figure shows an example of a typical web application running on EC2. The service credits for S3 Intelligent-Tiering, S3 Standard-Infrequent Access and S3 One Zone-Infrequent Access are: AWS offers service credits for non-compliance with the ALS operating time, but it is important to note that they are not applied automatically.
