How to implement Chaos Engineering using Kube Invaders

Reading Time: 3 minutes Chaos Engineering is the practice of performing random experiments to disturb the equilibrium of the deployment environment. Thus, this aims to check if an application is fault tolerant and highly available. The important reason behind Chaos engineering is to create highly available applications. Engineers use chaos engineering to cause chaos, random destructive operations in the deployment environment. This helps the engineers to reproduce many real-time Continue Reading
