Cloud storage may be cheap, but processing, moving, and managing data often isn't. This article examines seven common architectural patterns that inflate cloud bills, including small-file fragmentation, cross-region joins, excessive retention windows, poor storage tiering, and unrestricted queries. It argues that modern data engineers must think like FinOps practitioners, optimizing not just for performance and scale…
