Health checks provide a way to continuously monitor the health and status of an API or application. They help detect issues, failures, or degraded performance in real time. They identify downtime or unavailability, which can be critical for mission-critical applications.
In a load-balanced environment, they help distribute traffic to healthy instances. Load balancers can route requests away from unhealthy instances to maintain high availability and performance.
When an API or service fails a health check, automated processes or orchestrators (e.g., Kubernetes) can take action to restart or replace the failing instance, reducing downtime and manual intervention. Health check failures can trigger alerts and notifications to operations teams or administrators. This allows for rapid response and issue resolution.
