Kontaineriseerimise, often referred to as containerization, is a lightweight form of virtualization that allows applications to be packaged with all their dependencies and configurations into a single, isolated unit called a container. This container can then be run consistently across different computing environments, from a developer's laptop to a production server or cloud infrastructure.

The core concept behind containerization is to abstract the application away from the underlying operating system and hardware. This isolation ensures that an application behaves the same way regardless of where it is deployed, eliminating the common "it works on my machine" problem. Containerization typically involves technologies like Docker, which provides the tools to build, ship, and run containers.

Key benefits of containerization include increased portability, improved consistency, faster deployment cycles, and efficient resource utilization. Because containers share the host operating system's kernel, they are more lightweight and start up much faster than traditional virtual machines, which require a full operating system to be booted for each instance. This efficiency makes them ideal for microservices architectures, DevOps practices, and modern cloud-native applications. Containerization also facilitates easier scaling and management of applications.
