CloudWatch
A managed service that can be used to collect and analyze various cloud resource and application metrics and logs
- CloudWatch Logs supports a “destination” in a central account. You can configure other accounts to stream their logs to that destination, unifying them.
- This approach means all logs from multiple accounts end up in a single place for analysis
