Containerization
Packaging an application with all its dependencies into a standardized unit (container) that runs consistently across any environment.
Containerization, most commonly implemented with Docker, bundles an application's code, runtime, system tools, libraries, and settings into a lightweight, portable unit. Containers solve the 'works on my machine' problem by ensuring identical behavior across development, staging, and production environments. Container orchestration tools like Kubernetes manage multiple containers at scale, handling deployment, scaling, and failover automatically. Containerization is foundational to modern cloud infrastructure and enables horizontal scaling, blue-green deployments, and consistent development workflows.
