---
The Elastic Load Balancing (ELB) service from AWS distributes incoming application or network traffic across multiple targets, such as Amazon EC2 instances, in multiple Availability Zones. Monitoring the health of these instances is crucial for ensuring high availability and reliability of applications. The ELB Instance Health resource provides vital information on the health status of each instance associated with an ELB, enabling you to make informed decisions about your deployments. You can find more detailed information in the [official AWS ELB documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/elb-health-checks.html).
## Supported Methods
* `GET`: Get instance health by ID ((LoadBalancerName)/(InstanceId))
* `LIST`: List all instance healths
* ~~`SEARCH`~~

### [`ec2-instance`](/sources/aws/Types/ec2-instance)
The ELB Instance Health is directly related to EC2 instances, as it provides critical health status information for the instances that are associated with an ELB. This relationship helps monitor and manage the instances to ensure they can handle the traffic effectively. By linking to EC2 instances, users can better visualise and manage their application's infrastructure health and performance within the AWS ecosystem.
