Containerization is a method of packaging software applications and all their dependencies (libraries, frameworks, configuration files) into a single, isolated, executable unit called a container. This ensures the application runs consistently across different computing environments.
VMs virtualize the entire hardware stack, each running its own operating system. Containers, however, share the host operating system's kernel, making them much lighter, faster to start, and more resource-efficient than VMs.
Key benefits include enhanced portability, consistent environments across development and production, faster deployment, improved scalability, better resource utilization, and simplified application management.
Docker is a popular open-source platform that provides tools for building, deploying, and managing containers. It's often synonymous with containerization due to its widespread adoption and ease of use in creating and running containerized applications.
While containers offer isolation, their security depends on proper configuration, secure base images, regular vulnerability scanning, and adherence to security best practices. Sharing the host kernel means a vulnerability in the kernel could potentially impact multiple containers.
