What are the best practices for using multiple Network Load Balancers with an endpoint service?

Resolution

When you have multiple Network Load Balancers associated with an endpoint service, the endpoint interface connects to only one Network Load Balancer per Availability Zone. Use the same configuration for each of the Network Load Balancers to be sure that all endpoint consumers have a consistent service experience.

When configuring multiple Network Load Balancers with an endpoint service, confirm that each of the following are identically configured:

• Listener port and protocol
• Target groups and targets
• The application running on the target instances
