What is cloud waste?

Cloud waste is money spent on cloud resources that deliver no value, like idle servers, oversized instances, and storage no one remembers provisioning. Industry research has long estimated that a large share of cloud spend, often put at roughly a third, falls into this bucket.

It builds up quietly. A test environment left running over a weekend. An instance sized for a traffic spike that never comes back down. Snapshots kept long after anyone needs them. None of it feels expensive on its own, but it stacks fast.

The fix is visibility plus discipline: see where the waste is, clean it up, and automate the controls so it does not return.
