# HTTP Health Check

HTTP Health Check in Google Cloud Platform is used to monitor the health of instances in a load-balanced service. It periodically sends HTTP requests to specified endpoints and checks for valid responses. If an instance fails to respond correctly, it is marked as unhealthy and removed from traffic rotation until it recovers. This ensures high availability and reliability of applications.
