Kubernetes vs Docker: Differences Explained

Containerization has existed for decades but has seen increasing adoption in recent years for application development and modernization. This article covers two container solutions and their uses:

1. Docker, which is the container engine solution, its container orchestration solution Docker Compose, and Docker Swarm, which is a cluster-container orchestration solution.


2. Kubernetes, the alternative cluster-container solution, compares it to Docker Swarm to help you choose the one that best meets your requirements.

What Is Containerization?

A containerization is a form of virtualization at the application level. It aims to package an application with all its dependencies, runtimes, libraries, and configuration files in one isolated executable package, which is called a container. The operating system (OS) is not included in the container, which makes it different from virtual machines (VMs), which are virtualized at the hardware level and include the OS.
