AWS Lambda to Google Sheets with Keyless WIF
Sometimes the simplest reporting need turns into a bridge between two cloud worlds. In this case, the goal was not to build a large data pipeline or introduce a heavy analytics stack, but to make project metrics visible quickly, safely, and with as little operational burden as possible. The path led from AWS Lambda to Google Sheets, through Workload Identity Federation, without long-lived keys. Along the way, small limits, missing dependencies, and permission details shaped the final solution.
