Some applications may not respond during heavy load. These outages are due to out of memory and high CPU utilization when many requests are piled up at the application entry point since the back end is not available.

This article shows how to implement the Circuit Breaker pattern when an application is not responding using Red Hat OpenShift Service Mesh and IBM Cloud Pak for integration — the App Connect API service.
