title: AWS CloudFormation Rate Exceeded
body: <p>I am running a multi-branch pipeline in Jenkins for CI/CD that deploys a CloudFormation stack to my AWS account. Occasionally, when multiple developers push to their branches at the same time, I receive this error on one or more branches:</p>
  
  <blockquote>
    <p>com.amazonaws.services.cloudformation.model.AmazonCloudFormationException:
    Rate exceeded (Service: AmazonCloudFormation; Status Code: 400; Error
    Code: Throttling;</p>
  </blockquote>
  
  <p>This seems to be a rate limit that Amazon has imposed on the number of requests to CloudFormation within a specified time frame.</p>
  
  <p>What is the request limit of CloudFormation, and can I request a limit increase? </p>
