Scalability Evaluation on Zero Downtime Deployment in Kubernetes Cluster

This article investigates the relative impact of zero downtime deployment strategies on the scalability of applications within Kubernetes clusters. Ensuring uninterrupted service delivery while managing changing workloads is crucial in modern software development. Strategies like rolling updates, blue-green deployments, and canary releases enable seamless updates without service interruptions. However, their comparison implications on application scalability in Kubernetes clusters remain understudied. We conducted an in-depth comparative analysis of these deployment strategies, assessing their performance on scalability patterns, performance metrics, resource utilization, and operational metrics. Our findings offer valuable insights into the effectiveness of zero downtime deployment strategies for scalable application delivery in Kubernetes environments. Understanding these relative impacts helps organizations make informed decisions for resilient and scalable application management.
