🐧 Red Hat Enterprise Linux (RHEL): The Power of Enterprise-Grade Linux

📜 What is Red Hat Enterprise Linux?

Red Hat Enterprise Linux (RHEL) is a Linux distribution developed by Red Hat, one of the most well-known companies in the open-source software industry. RHEL is tailored specifically for enterprise environments, offering stability, security, and extensive support for businesses running critical workloads.

Launched in 2000, RHEL was designed to be the perfect platform for businesses that require a reliable and secure operating system to run on their servers, workstations, and cloud environments. Red Hat provides a subscription-based model for RHEL, which includes technical support, security patches, and certified software updates. This level of service is crucial for enterprises that need guaranteed uptime and reliability.

RHEL is built on the foundation of the open-source community, which means it shares a significant portion of its codebase with other Linux distributions such as CentOS and Fedora. However, unlike these distributions, RHEL is geared toward production environments and commercial support, ensuring that enterprises can rely on it for long-term stability and security. Moreover, Red Hat has established a global presence, offering localized support and services for businesses around the world.
