Introducing The Basics Of Linux container

Linux is an open source operating system. When we talk about Linux, you should also talk about Linux container. It is basically a set of processes that are completely isolated from the rest of the system. A Linux container runs from a unique image and provides all the required files for process support.

Linux container is portable right from the stage of development, testing and production. The container holding your application will have all the required files and configurations. Hence, you will be able to move the data from development to testing without any major side effects.

Yu can apply the concept of Linux container in a wide range of scenarios where you need isolation, portability, and configuration. It doesn't matter whether your environment is on-premise, cloud or hybrid. The Linux container will be able to work anywhere.

If you ask whether Linux containers are similar to virtualization, then the answer could be yes or no. With Virtualization, you will be able to run multiple operating systems on a single laptop or computer. Meanwhile, containers share the same operating system but isolate the application process from the rest of the system.

Linux containers will be able to run a single operating system. It shares all other containers. Hence, your apps and services will remain lightweight and runs parallel.

The concept of container technology surfaced in 2000 as FreeBSD jail. It enabled partitioning of a FreeBSD system into multiple subsystems or jails. In 2001, Jacques Gelinas created VServer project, which is an isolated environment implementation. In 2008, the container world was disrupted with Docker. It combined the LXC with enhanced tools for developers. As of this writing, Docker is a popular technique for the deployment and management of Linux containers.

Linux containers portray how developers build, deploy, and manage applications. The container image not only provides portability but also version control. If you work something on a laptop, it will also work in the production system without any fault. When compared to a virtual machine, a running Linux container is less resource hungry. However, it retains application isolation and can be easily managed as part of a large application.
