Overview

This article dives into the transformative process of adapting legacy applications for Kubernetes. It begins with the fundamental need for decoupling, illustrating with a MySQL database’s transition from a monolithic to a microservices approach. It further explores the importance of decoupled resources, using RabbitMQ to demonstrate the shift from fixed configurations to dynamic service intermediaries that enable scalability and maintainability.
