Explore log architecture

Use the log architecture explorer to see how CloudWatch Logs organizes data in a three-level hierarchy: Log Group, Log Stream, and Log Event.

The explorer shows how Lambda and ECS automatically create log groups and streams, and how the Unified Agent sends EC2 logs to CloudWatch. Toggle between different source types to see how each one creates its log structure.

Question: A Lambda function is invoked 100 times in one hour. How many log streams does CloudWatch create?
