Understanding Linux

There are many different versions of Linux. Learn which one is right for your needs.

Learn the difference between these two popular Linux distros, and how community and enterprise development models intersect.

Planning a shift to the cloud? Linux is there.

This open source community project creates CentOS Stream, a distro that incorporates features and innovations from Fedora, generally just ahead of Red Hat Enterprise Linux.

An IT system is described as having high availability when it has near-zero downtime. Linux can be customized to operate with this level of responsiveness.

Enterprise resource planning (ERP) software helps business processes run more efficiently, giving organizations a single source of truth for data used across departments.

SAP HANA is an in-memory database that helps organize and analyze big data for SAP’s enterprise resource planning (SAP ERP) applications.

High-performance computing (HPC) generally refers to processing complex calculations at high speeds across multiple servers in parallel. Linux is the dominant OS in this field.

Servers can run variants of Linux to handle the most demanding business applications, such as web services and databases.

The Linux kernel is present in all Linux distros, controlling core functions like memory management.

Linux certifications—offered by many organizations in the open source community, including Red Hat—demonstrate proficiency with various aspects of Linux OS management.

Security-Enhanced Linux (SELinux) is a security architecture for Linux systems that allows administrators to have more control over who can access the system.

See how Linux supports applications that rely on minimal latency to function.

Linux containers let you isolate 1 or more processes from the rest of a system, bundling applications with their supporting files and runtime processes.

An image builder is a tool used in system administration to create a copy—an exact image—of a virtual system or configuration.

A golden image is an intentionally configured snapshot of a system that can be used as a baseline to deploy new instances.
