Over the last decade, the software industry has undergone a massive shift from monolithic architectures toward distributed, microservices-based systems. This transformation has been fueled by the rise of containerization, particularly Docker, which enables developers to encapsulate applications and their dependencies into lightweight, portable units that run consistently across environments. But while containers solve the problem of application portability, they introduce a new challenge: orchestrating, scaling, securing, and monitoring hundreds if not thousands of these containers across production-grade environments.
