Most cloud cost guides focus on compute, storage, and network egress. But a new, invisible tax is eating into margins: telemetry. As organizations shift to observability-first architectures, the volume of logs, metrics, and traces generated by every API call has exploded. In this episode, Lucas and Luna break down how data collection itself becomes a line item that rivals your largest database bills. We look at a specific mid-market SaaS company that reduced its infrastructure spend by twenty-eight percent not by resizing servers, but by restructuring how it ships telemetry data to its monitoring vendor. The conversation covers sampling strategies, edge filtering, and why keeping every single log entry in hot storage is a financial error most CTOs make today.
