Implementing resilient applications with API Gateway (Health Check)

1

Kubernetes

For example, when you are using orchestrators like Kubernetes and Service Fabric periodically perform health checks and determine that a service/container is unhealthy, it stops routing requests to that instance. It also usually creates a new instance of that container.

Apache APISIX

Apache APISIX API Gateway supports almost all modern resiliency patterns like the timeouts, fallbacks, retry, and circuit breaker I discussed in another blog post Implementing resilient applications with API Gateway (Circuit breaker), which can also be applied to your Microservices APIs. Apache APISIX Health check mechanism performs health checks on each target upstream service regularly, marking it as healthy or unhealthy based on whether they are responsive or not. You can also retrieve anytime the health status of specific nodes by using the Control API-health check endpoint.
