Containers are essentially like lightweight and portable virtual machines. They provide a way to package an application's code, configurations, and dependencies into a single image, alongside the operating system, that can be easily shared and run in any environment.
You can use Docker, the most popular containerization platform, to create a container image. The image defines the dependencies, OS and runtime. You can use the image to spawn a container on any computer or server with Docker installed. This makes it easy to develop and deploy applications in a consistent and reproducible way, regardless of the underlying infrastructure.
