This Project focuses on providing a collection of resources to help identify types of cloud cost waste by service provider, including links to additional tools. You can sort each card by cloud service provider or savings potential.
Filter by cloud provider:
Filter by saving potential:
Analyze CPU, memory, disk, and network utilization. Anything with 0 across all 4 metrics in the last 14 days we flag the resource as being idle.
Check how often you are running full DynamoDB backups; they could be running every 5 minutes with no retention policy. Over time these costs compound. Determine if the business requires this much backup data, if not one option is to switch to a solution of using point-in-time recovery for Dynamo.

Manually investigate the largest vendor spend. Create scripts that swaps out license sizing and the infrastructure underneath.

Unattached EIP cost $0.005 an hour. Over time this can compound into a waste of money. Also if there is something causing these EIPs to be unattached this problem will grow.

Read the story Code exampleScripts can be implemented to scan and terminate unattached EBS volumes. Consider taking snapshots in higher environments before terminating the volumes. Many scripts can be found in github or elsewhere on the Internet. (Noel's story)

Read the story Related materialAWS Storage Lens or your dedicated Technical Account Manager can identify MPU's in S3 buckets. Once you identity MPU's on specific buckets, you can configure a lifecycle rule for those S3 buckets to automatically abort 7-day old (or whatever time period you find appropriate) incomplete multipart uploads. I'd argue that lifecycle rules on S3 buckets should be the default, not the exception. A full description of the services and outline of this process can be found in the AWS blog post here.
Related materialThere are multiple ways to attack a lifecycle of snapshots in general. With EBS, you can use Amazon Data Lifecycle Manager to automate the retention of your snapshots. You can also use a myriad of 3rd party tools to help manage the data lifecycle of snapshots. I recommend first establishing a policy within your organization, communicate & collaborate on the policy, and enforce the policy with the ability to opt out.

Code exampleFailure to purchase org level capacity commitments for BigQuery can result in runaway costs due to on-demand query costs. Purchasing an org level capacity commitment and enabling idle capacity at the org level can ensure stable BigQuery costs across the organization. Consideration also needs to given be to whether the location supports multi-region commitments or if separate commitments will need to be purchased for each region or location where workloads are provisioned.

Application packing places nodes into the "Idle" category, per cloud provider, requires understanding of daemon sets and other non-redistributable pods.
