Health Checks
Explore how load balancer health checks prevent traffic routing to failing instances, improving system stability. Learn about session stickiness for stateful services and how content-based routing can partition requests to optimize performance and scalability.
We'll cover the following...
Load balancer health check service
One of the most important services a load balancer can provide is service health checks. The load balancer will not send traffic to an instance that fails a certain number of health checks. Both the frequency and number of failed checks are configurable per pool. Refer back to Health Checks for some details about good health checks.
Stickiness
Load balancers can also attempt to direct repeated requests to the same instance. This helps when we have stateful services, like user session state, in an application server. Directing the same requests to the ...
