Kubernetes: how to isolate your production from staging

A Kubernetes cluster is a collection of nodes designed to manage application workloads resiliently, ideal for maintaining operations during node disruptions. A staging cluster, used for testing and validation, mimics the production cluster to ensure similar environments, allowing changes and testing without affecting the production application. Production clusters, intended for end-user access, must be stable and secure, with limited access to reduce error risks. Using separate clusters for staging and production enhances performance, security, and productivity by isolating environments, preventing data leaks, and allowing faster iteration. Setting up these clusters with tools like Qovery involves creating and deploying both staging and production environments, which can cost approximately $540 monthly on AWS for two clusters. Employing distinct clusters helps prevent costly production disruptions and ensures a stable client experience.
