Implement a Circuit Breaker for an Unavailable API Service Running in App Connect on CP4I Using Red Hat Service Mesh

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. In this article, we will solve this problem using Red Hat OpenShift Service Mesh, which provides a way to stop sending requests to the application or API if it is unhealthy. 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.
