Containerization

Containerization is a lightweight form of virtualization that involves packaging an application and its dependencies into a single, self-contained unit called a container. Containers run consistently across different computing environments, from development to production, regardless of the underlying infrastructure.

Unlike traditional virtual machines, containers share the host system’s operating system kernel, which makes them faster to start, more efficient in resource usage, and easier to manage. Popular containerization platforms include Docker, Kubernetes, and Podman.

Containerization enhances application portability, scalability, and deployment speed. It is widely used in DevOps, cloud computing, and microservices architectures to support continuous integration and continuous deployment (CI/CD) workflows.
