What is Red Hat Enterprise Linux?

Red Hat Enterprise Linux (RHEL) is an operating system developed and supported by Red Hat. It is based on an open-source approach and provides robust performance along with reliability. RHEL is commonly used in large enterprise environments, catering to the needs of businesses by offering a range of features.


RHEL leverages the extensive features and performance advantages of Linux. The operating system boasts a scalable and robust architecture. Known for its modular design and built on a powerful kernel, RHEL’s fundamental architecture allows it to scale according to workloads and operate on various hardware architectures.

Management Tool: Red Hat Enterprise Linux Management

RHEL comes with a robust set of management tools. The Red Hat Enterprise Linux Web Console, a proprietary management tool from Red Hat, offers a web-based user interface, providing system administrators with ease of use. Additionally, a range of command-line tools and graphical interfaces offers a broad spectrum of options for system configuration, monitoring, and troubleshooting.


Security is of critical importance for large enterprises, and RHEL addresses this need with a variety of security features. RHEL enhances network security with tools such as Secure Boot, Secure Shell (SSH), and firewalld. Furthermore, security measures at the operating system level, such as Security-Enhanced Linux (SELinux), provide protection.

Performance and Scalability

RHEL is designed to manage and scale workloads effectively. With advanced performance optimizations, it supports high-demand applications. Additionally, it provides scalability through cloud integration and virtualization technologies, enabling rapid adaptation to changing business needs.
