Our small DevOps/CloudOps team uses OpsCompass to track the cloud resources in our AWS instances. When we started using it, we set a baseline of cloud resources--and OpsCompass runs daily scans to detect any changes compared to the baseline. It's been an extremely helpful tool to provide us with a clear, up-to-date view of all the resources in our clouds. Before OpsCompass, getting a complete inventory of resources was surprisingly hard, and now it's surprisingly easy. We can detect which resources have increased and whether those changes came from a user or a system.
We recently added resource costs to OpsCompass, which now gives us the cost impact of the changes happening in our AWS instance. This will easily pay for OpsCompass--instead of a bill from AWS for last month's unexpected cost surges, we'll see them right away and can intercept unexpected cost increases.
