Identify any Amazon ELBs that appear to be idle and consider to terminate them.
By default, an Elastic Load Balancer is considered 'idle' when meets the following criteria:
- The sum of the requests made to the load balancer in the past 7 days is less than 100.
Audit / Verification
Step 01: Sign in to the AWS Management Console.
Step 02: Navigate Load Balance under Load Balancing section
Step 03: Select your Elastic Load Balancer and navigate the Monitoring tab
Step 04: Select to view the Sum Requests (Count) usage graph. Verify the RequestCount usage for the last 7 days to check if the sum of the requests made to the Elastic Load Balancer in the past 7 days is less than 100, e.g.
It is recommended to check tagging to decide whether it's safe or not to terminate the resource.
Step 05: Repeat steps no. 4 to verify the RequestCount usage and the necessary tags for the rest of the load balancers in the current region.
Step 06: Switch to the other AWS regions and follow the same above audit process.
