Idle Transit Gateway, No Traffic

A transit gateway bills an hourly charge per attachment regardless of traffic, so attachments carrying nothing still cost the same as attachments carrying everything.

Free to start. No card. The playground just needs your work email.

Found, explained, fixed.

Findings with a dollar figure attached, idle, oversized, orphaned, unscheduled and undiscounted spend.

01

Detect

ZopNight checks this automatically across AWS, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Delete the idle transit gateway. Where the saving can be proven it is priced; where it cannot, the finding says so.

03

Fix

After a guided review, where you confirm the change, ZopNight deletes the resource, then checks the change took.

Transit Gateways on AWS
The fix, by hand
  1. Verify no VPCs, VPNs, or Direct Connect gateways need this TGW.
  2. Remove any remaining route table associations.
  3. Delete the Transit Gateway.
  4. Update any referencing CloudFormation stacks.

ZopNight does this for you after a guided review.
