Load Balancing Checklist

  • All backend servers are identical in the content being served
  • A self-signed certificate shared across the servers that can be trusted by the load balancer is in place on the service
  • Service health monitor for the service is defined in documentation (What health check can be used to determine if the service is running?)
    • Example: Querying https://servername.txstate.edu/healthcheck will return 200 if the services are running
  • It is best to have the service up and configured across the backend servers prior to requesting load balancing so that validation can be completed during configuration
  • Limit traffic on backend nodes so it’s only available to the load balancer. (IP’s provided on request)
    • This is to ensure all traffic is routed through the load balancer.
    • Exceptions to this are permitted if the backend nodes will need to be accessed by the clients.

Note: Any modifications after initial setup will require a change request.
