Evolution of Deployment: From Bare Metal to Kubernetes (K8s Explained)

Building an application is one challenge, but deploying it efficiently and scaling it for real-world users is an entirely different game. Over the years, deployment strategies have evolved significantly—from physical servers to modern container orchestration tools like Kubernetes. In this blog, we will understand this journey step by step. Step 1: Application Development Let’s assume a developer builds an application using: Node.js Redis PostgreSQL The choice of tech stack depends on the developer’s comfort and project requirements. Once the application is ready on the local machine, the next step is deployment. tep 2: Traditional Deployment (Bare Metal Servers) To make the application publicly accessible, the developer needs a server. Options: Buy a physical server ( Bare Metal ) Rent a server from a third-party provider Process: Deploy application on server Purchase a domain Map domain to server’s static IP Now the application is live 🎉 Challenges in Traditional Deployment 1.
