Amazon CloudWatch alternatives: Azure, Google Cloud and open source

CloudWatch is where the logs, the numbers and the alarms live.

Your success signal has to be captured automatically, and this is usually where it lands. For AI systems: latency, errors and cost per call.

You get backDashboards, alarms, and the ability to ask what happened
What it costsPer gigabyte ingested and stored, and per metric. Debug logging left on is a real budget line.
Who operates itAWS collects and keeps. Deciding what is worth measuring is yours, and it is the harder half.
When it is the wrong choiceNever wrong. But a number nobody looks at is not a signal, however carefully it was collected.

AWS calls it: “Observe and optimize your workloads at any scale”[1]

How I use it

Logs, metrics and alarms. The first-approval rate in my video pipeline is a CloudWatch metric.
