Docker Containerization
Docker containerization is a technology that packages an application and all its dependencies—such as libraries, system tools, and runtime—into a standardized, isolated unit called a container. This self-contained package ensures that the application runs consistently and reliably across different computing environments, from a developer's laptop to production servers, effectively solving the "it works on my machine" problem. Unlike traditional virtual machines that virtualize an entire operating system, containers share the host system's kernel, making them significantly more lightweight, faster to start, and resource-efficient, which simplifies the process of building, shipping, and deploying software.
