Overview

After a backend server group is created, you can modify its health check settings and basic information.

Health Check

If backend servers have to handle large number of requests, frequent health checks may overload the backend servers and cause them to respond slowly. To address this problem, you can prolong the health check interval or use TCP or UDP instead of HTTP. You can also disable health check. If you choose to disable health check, requests may be routed to unhealthy servers, and service interruptions may occur.

For details about the health check, see Health Check.

For details about how to modify health check settings, see Modifying Health Check Settings.
