Amazon DynamoDB Service Level Agreement
Last Updated: March 14, 2019
This Amazon DynamoDB Service Level Agreement ("SLA") is a policy governing the use of Amazon DynamoDB ("DynamoDB") and applies separately to each account using DynamoDB. In the event of a conflict between the terms of the AWS Customer Agreement or other agreement with us governing your use of our Services (the "Agreement"), the terms and conditions of this SLA apply, but only to the extent of such conflict. Capitalized terms used herein but not defined herein shall have the meanings set forth in the Agreement.
AWS will use commercially reasonable efforts to make DynamoDB available with a Monthly Uptime Percentage for each AWS Region, during any monthly billing cycle, of (a) at least 99.999% if the Global Tables SLA applies, or (b) at least 99.99% if the Standard SLA applies (the "Service Commitment"). In the event DynamoDB does not meet the Service Commitment, you will be eligible to receive a Service Credit as described below.
Service Credits are calculated as a percentage of the following charges paid by you for DynamoDB for the monthly billing cycle in which the Monthly Uptime Percentage for a given AWS Region fell within the ranges set forth in the table below: (a) if the Global Table SLA applies, the total charges paid by you for DynamoDB for the AWS Region plus the charges described in the Global Tables section of the Amazon DynamoDB Pricing page of the AWS website paid by you for corresponding replica tables in other AWS Regions, or (b) if the Standard SLA applies, the total charges paid by you for DynamoDB in the applicable AWS Region.
|Monthly Uptime Percentage||Service Credit Percentage
|Global Tables SLA
||Less than 99.999% but equal to or greater than 99.0%
|Less than 99.0% but equal to or greater than 95.0%||25%
|Less than 95.0%||100%|
||Less than 99.99% but equal to or greater than 99.0%
|Less than 99.0% but equal to or greater than 95.0%||25%|
|Less than 95.0%||100%|
We will apply any Service Credits only against future DynamoDB payments otherwise due from you. At our discretion, we may issue the Service Credits to the credit card you used to pay for the billing cycle in which the unavailability occurred. Service Credits will not entitle you to any refund or other payment from AWS. Service Credits will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one dollar ($1 USD). Service Credits may not be transferred or applied to any other account. Unless otherwise provided in the Agreement, your sole and exclusive remedy for any unavailability or non-performance or other failure by us to provide DynamoDB is the receipt of Service Credits (if eligible) in accordance with the terms of this SLA.
Credit Request and Payment Procedures
To receive Service Credits, you will need to submit a claim by opening a case in the AWS Support Center. To be eligible, the credit request must be received by us by the end of the second billing cycle after which the incident occurred and must include:
i. the words "SLA Credit Request" in the subject line;
ii. the billing cycle and AWS Regions with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for that AWS Region for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability in that AWS Region throughout the billing cycle;
iii. your Request logs that document the errors for your claimed outage (any confidential or sensitive information in these logs should be removed or replaced with asterisks).
If the Monthly Uptime Percentage of such credit request is confirmed by us and is less than the Service Commitment, then we will issue the Service Credits to you within one billing cycle following the month in which the credit request occurred. Your failure to provide the credit request and other information as required above will disqualify you from receiving Service Credits.
DynamoDB SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension or termination of DynamoDB, or any other DynamoDB performance issues: (i) caused by factors outside of our reasonable control, including any force majeure event or Internet access or related problems beyond the demarcation point of DynamoDB; (ii) that result from any voluntary actions or inactions from you or any third party; (iii) that result from you not following the best practices described in the DynamoDB User Guide on the AWS Site; (iv) that result in additional recovery time due to insufficient read capacity units (RCUs) and write capacity units (WCUs) provisioned for your database workload; (v) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment within our direct control); or (vi) arising from our suspension and termination of your right to use DynamoDB in accordance with the Agreement (collectively, the "DynamoDB SLA Exclusions").
If availability is impacted by factors other than those explicitly used in our Monthly Uptime Percentage calculation, then we may issue a Service Credit considering such factors at our discretion.
- "Availability" is calculated for each 5-minute interval as the percentage of Requests processed by DynamoDB that do not fail with Errors. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
- The Global Table SLA Availability calculation considers all Requests for all of your DynamoDB tables in the AWS Region and also their corresponding replica tables in other AWS Regions.
- The Standard SLA Availability calculation considers all Requests for all of your DynamoDB tables in the applicable AWS Region.
- An "Error" is any Request that returns a 500 or 503 error code, as described in DynamoDB Common Errors on the AWS Site.
- The “Global Table SLA” is the Service Commitment that applies if all of your DynamoDB tables in the applicable AWS Region are part of global tables as described on the AWS Site ("Global Tables") throughout the applicable monthly billing cycle, and you make reasonable attempts to failover in the event of an availability issue in a single AWS Region.
- "Monthly Uptime Percentage" for a given AWS Region is calculated as the average of the Availability for all 5-minute intervals in a monthly billing cycle. Monthly Uptime Percentage measurements exclude downtime resulting directly or indirectly from any DynamoDB SLA Exclusion.
- A "Request" is a customer-initiated action of a type specifically listed as being supported by DynamoDB in the DynamoDB API Reference Documentation on the AWS Site. For the avoidance of doubt, Requests do not include actions listed under other products or services (e.g., Amazon DynamoDB Accelerator, Amazon DynamoDB Streams).
- A "Service Credit" is a dollar credit, calculated as set forth above, that we may credit back to an eligible account.
- The "Standard SLA" is the Service Commitment that applies if any of your DynamoDB tables in the applicable AWS Region are not part of Global Tables, or if the Global Table SLA would otherwise apply but you do not make reasonable attempts to failover in the event of an availability issue in a single AWS Region.
