This article explains when you can use a custom proxy client with the Flexera Health Check Service (HCS) and how it works with your private EC2 instances.

How the Flexera health check service works

The Flexera Health Check Service acts as a proxy between Elastigroup hosts and your private EC2 instances in your VPC. During each health check:

• Elastigroup triggers the proxy service.

• The proxy communicates with your private instances.

• The proxy sends the results back to Elastigroup.

• If an instance is unhealthy and the Elastigroup Health Check Type is set to HCS, Elastigroup replaces the instance based on your configuration.

You can learn more in the Custom health check service documentation.

Using a custom proxy client

Yes, you can build your own proxy client. You can create a custom proxy agent that uses the Health Check Service API. This lets you modify how the proxy behaves or extend the logic for your environment.
