@singhgss While testing on LZA, we got the following error

Issue Encountered

• During testing in the LZA environment, a new account creation triggers the org role creation Lambda function.
• The Pipeline Role with admin privileges is not created immediately as the LZA pipeline is still in progress.
• The role is created approximately 20 minutes after the account creation.

Current Implementation

• Implemented retry logic in the Lambda function with exponential backoff.
• Lambda function attempts to assume a role that is created around 20 minutes post-account creation.
• Lambda function has a maximum execution time of 15 minutes, causing it to reach this limit before the necessary role is available.

Consideration

• Currently considering forcing an update on the stack to ensure new accounts are included in the update cycle.
• This would ensure the new GCExecutionRoles are created for new accounts.

Proposed Solution

• Option 1: Create a DynamoDB table and inject new account information into it using the new account created event.
  • Schedule a time event to trigger role creation on accounts listed in the DynamoDB table.
  • Remove records from the table once role creation succeeds.
• Option 2: Use tagging on org accounts to indicate if roles have been deployed and when they were last updated.
  • This approach allows flexibility to trigger role updates by removing the tag.
  • Schedule role deployment every 4 hours for eventual consistency.
  • Easily identify which accounts have roles applied.

Preferred Solution

• Using tagging seems preferable as it provides a way to trigger role updates and manage deployment effectively.
