Most expensive cloud surprises are a mismatch between how a workload actually behaves and how it is being paid for. That mismatch is legible once you know where to look.

Start with what genuinely changed when capacity became an API call, learn to read a bill in a fixed order, and finish on the choice most teams make on instinct: rent the operating burden, or carry it yourself.
