Konteinerointiin, commonly referred to as containerization, is a lightweight form of virtualization that allows applications to be packaged with their dependencies and configurations into isolated user-space instances called containers. These containers run on a shared operating system kernel, making them more efficient in terms of resource utilization and startup time compared to traditional virtual machines.

The core idea behind containerization is to isolate applications from their environment. This ensures that an application will run consistently regardless of where it is deployed, whether on a developer's laptop, a staging server, or a production cloud environment. This consistency is achieved by bundling the application code, runtime, system tools, libraries, and settings all within a single container image.

Popular containerization technologies include Docker and Kubernetes. Docker provides the tools to build, ship, and run individual containers. Kubernetes, on the other hand, is a container orchestration system that automates the deployment, scaling, and management of containerized applications across clusters of machines.

Containerization offers several advantages, including improved portability, faster deployment cycles, increased developer productivity, and better resource efficiency. It simplifies the management of complex applications and microservices architectures, enabling organizations to build, test, and deploy software more rapidly and reliably. This approach has become a cornerstone of modern software development and DevOps practices.
