The following article describes Docker and Traditional Virtualization.
Docker is an open-source platform that allows developers to build, package, and deploy applications as lightweight, portable containers. It uses operating-system-level virtualization to run multiple containers on a single host, with each container sharing the host’s kernel.
In traditional virtualization, a hypervisor is used to create virtual machines that emulate a complete operating system, including its kernel. Each virtual machine runs independently of the host and other virtual machines and requires its own resources such as memory, CPU, and storage.
The main difference between Docker and traditional virtualization is that Docker containers are more lightweight, portable, and efficient. They share the host’s operating system kernel. Hence, they are smaller in size. So, the resource requirement for Docker containers is also less than virtual machines. This makes Docker containers faster to deploy, easier to manage, and more flexible in terms of scaling and distributing applications.
Additionally, with Docker containers, we can package applications and dependencies together. Therefore, they can be easily deployed and run on any platform that supports Docker. This makes it easier to ensure consistency across different environments and simplifies the deployment process.
