Most cloud platforms support both TCP- and HTTP-based checks. To integrate health checks with your selected cloud platform, you need to configure your cloud deployment to point to the HTTP entry point, /health, on the node that hosts your application.
The cloud platform will invoke a GET query on the HTTP entry point; all checks that are registered will be performed and the sum of individual checks determines the overall outcome.
Usually, the response payload is ignored by the cloud platform and it only looks at the HTTP status code to determine the liveness or readiness of your application. A successful outcome, UP, will be mapped to 200 and DOWN to 503.
