AWS monitoring built for cost control and data residency
What AWS monitoring covers, why the bill outruns the account it watches, and what changes when the platform runs inside your own AWS environment.

Definition
AWS monitoring is the practice of collecting and reading metrics, logs, and traces from the AWS services your applications run on, from EC2 instances and containers through to managed databases and serverless functions, so you can tell whether the platform and the applications on it are healthy. It overlaps with infrastructure monitoring and for most teams it starts with CloudWatch, which is also where the cost question usually turns up for the first time.
Your AWS monitoring bill grows faster than the infrastructure it is meant to explain, and finance wants to know why. Most platforms collect telemetry inside your account, ship it to a vendor's cloud, then charge you again to store what you already paid to generate. This guide covers why that happens, and what changes when the platform runs inside the account instead.
