Migrating a cloud application to Kubernetes

The blog post explores the process and benefits of deploying a PERN (PostgreSQL, Express, React, Node.js) application to Amazon EKS using Kubernetes and Pulumi. It highlights Kubernetes' advantages, such as minimizing downtime, facilitating updates, and enabling scalable infrastructure across multiple cloud providers like AWS, Azure, and GCP. The document provides a step-by-step guide on setting up the application, starting from cloning the Typescript PERN example, configuring necessary variables, and integrating Pulumi for infrastructure management. The process involves the creation of a PostgreSQL Docker container, setting up Kubernetes deployments and services for the database, server, and client components, and utilizing AWS Elastic Kubernetes Service to manage the application's scalability and resilience. The post concludes with a preview of an upcoming exploration of applications using the MERN stack, emphasizing the scalability and efficiency of containerized services for growing applications.
