A lightweight virtualization method that packages applications and their dependencies into portable, isolated containers that can run consistently across different computing environments. Unlike traditional virtual machines, containers share the host operating system kernel, making them more resource-efficient and faster to start.

Container Benefits

Containerization solves the "it works on my machine" problem by ensuring applications run identically across development, testing, and production environments. Containers provide process isolation, resource control, and simplified deployment workflows while maintaining minimal overhead compared to full virtualization solutions.

Container Ecosystem

The containerization ecosystem includes container runtimes like Docker, orchestration platforms such as Kubernetes, and container registries for storing and distributing container images. This technology enables microservices architectures, continuous integration/continuous deployment pipelines, and cloud-native application development.
