Tag: Cent OS

AlmaLinux is a relatively new operating system meant to act as a CentOS replacement. How did AlmaLinux come to be? RedHat, the company that created and maintains RedHat Enterprise Linux (RHEL), announced on December 8th, 2020, that CentOS would be repurposed to CentOS Stream. CentOS Stream now acts as an upstream testing platform where new and updated software will first be deployed and tested before being released to RHEL users. 

What is Docker?

Docker is a containerization software that is used for automating the deployment and management of applications within an isolated environment. This software allows us to "pack" and ship an application, along with all of its needed files, libraries, and dependencies, into a "docker container". That container can then be easily ported to any Linux system that contain cgroups support within the kernel, and provides a container management environment. Docker is one of several containerization implementations (not to be confused with virtualization) based on this cgroups mechanisms built into the Linux kernel.

What is Docker?

Before we begin, let's describe what Docker is. Docker is a set of virtualization tools that allows us to create, test, and deploy containerized applications quickly and easily on a dedicated server. It has become very popular and used almost everywhere in our daily lives. Thanks to containerization, we can quickly launch applications on different private cloud hosting platforms utilizing small bundles which contain all the needed packages, libraries and configuration file to run an application. These docker packages communicate via established network channels.

Fast, Portable and Secure.

Containerization is a technology that is taking the IT world by storm! It’s no surprise considering the considerable benefits of shifting to a container based deployment.
