ELB Health checks on Multiple Target Groups (multiple domains)
Posted on: Dec 24, 2018by: Suresh P
I am trying to utilize ELB's Host based routing to server multple domains using the same ELB instead of one ELB for each domain in order to reduce the cost.
Before doing that, i would like to know how the ELB health checks are going to work if i have multiple target groups.
Do i need to have a generic script (URL) on all target group's instances to validate the healthcheck?
Is it a sensible way to proceed?
The load balancer will send health checks to its targets that have been registered with a target group. These health checks are initiated by the load balancer and are configured in the target group settings in the AWS console.
