The container is a lightweight, portable, and self-sufficient software package that includes all the necessary components to run an application, such as code, runtime, libraries, and system tools. Containers isolate applications from their environment, ensuring they run consistently across different computing environments. Unlike virtual machines, containers share the host system’s operating system kernel, making them more efficient and faster to start. This technology enhances development, deployment, and scalability, allowing applications to be moved seamlessly between development, testing, and production environments. Containers are managed and orchestrated using tools like Docker and Kubernetes.
