## AI overview

This article explains how Kubernetes redundancy helps applications tolerate failed Pods, deployments, and worker nodes. It covers replica management, failure detection, traffic rerouting, replica recovery, and the role of managed Kubernetes services such as Amazon Elastic Kubernetes Service in adding or removing worker nodes. It also introduces Gremlin's Recommended Scenarios for verifying cluster resilience.
