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. This Amazon RDS Service Level Agreement (“SLA”) is a policy for using the Amazon Relational Database Service (“Amazon RDS”) and applies separately to each account used by Amazon RDS. 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. For all RDS areas hosted in multiple availability areas (the “Multi AZ” setting is defined as “True”), Amazon guarantees 99.5% operating time on each monthly billing cycle. This allows up to 3.65 hours of downtime per month. For applications that cannot tolerate downtime, customers should consider hosting their databases in multiple regions or using another database service, such as Amazon Aurora, which has an ALS with a 99.99% operating time. Like other Amazon services, the hosted database service includes installation, operation and scale. For example, the service automatically patches database software and creates data. According to Amazon, the code, applications and tools that computer scientists already use with their local databases can also be used with RDS.
“Cool Access Tier” is an attribute of a memory account that indicates that account data is rarely accessible and is less available than data at other access levels. The accumulation of benefit credits and the payment of penalties are two major remedies for non-compliance with the ALA. The first is to reduce the fees to be paid; the second relates to the amount to be paid by the supplier. Cloud service providers AWS and Azure always have the first option to allocate “service credits” in the event of a violation in their SLAs. The examples presented give rise to an expected availability of 99.80% to 99.92% depending on the services concerned. “Service credit” is the percentage of monthly service charges in effect that are credited to customers after the debt is approved. Credits are the only form of compensation for missed service obligations in all controlled ALSs, regardless of service models. The calculation of service credits varies considerably from provider to provider. The combination of customer acceptance, many new features and extensive operational experience has taken RDS (Relational Database Service) to a level where Amazon believes it is mature enough to be made accessible to all.
