AWS Application Load Balancer

Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. An Application Load Balancer functions at the application layer, the seventh layer of the Open Systems Interconnection (OSI) model.

The metrics for AWS ALB are obtained through AWS Cloudwatch by using the YACE exporter.
