Konténerrizáció

Konténerrizáció, often referred to as containerization, is a method of operating system-level virtualization that allows applications to be packaged and run in isolated environments called containers. Each container encapsulates an application and its dependencies, such as libraries, binaries, and configuration files, ensuring that it runs consistently across different computing environments. This isolation prevents conflicts between applications and their dependencies, simplifying deployment and management.

The core principle behind containerization is to share the host operating system's kernel while providing each container with its own isolated user space. This differs from traditional virtual machines, which virtualize the entire hardware stack and require a separate operating system for each VM. Containerization is significantly more lightweight and efficient, leading to faster startup times and lower resource consumption.

Popular containerization platforms 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 has become a cornerstone of modern software development and DevOps practices, enabling greater agility, portability, and scalability for applications. It facilitates microservices architectures, CI/CD pipelines, and cloud-native development.
