The rule “Lambdas have a unique role” will be deprecated in a rules update in 7 days. This rule has been a part of the Stax compliance module for many years, and after careful consideration, we have decided that it no longer serves its intended purpose.

This rule was originally intended to ensure that AWS Lambdas — cloud computing functions — had a unique role within the environment. As cloud computing and serverless functions have evolved, we have determined that this rule does not provide additional security and is no longer necessary.

This rule is only part of the Stax rule catalog, and is not used as part of any compliance or best practice rule bundles.
