Red Hat Enterprise Linux

Introduction

A large percentage of the servers hosting websites, cloud-based services and virtualization services are powered by Linux. The Linux operating system is favored by many IT departments due to its reputation for stability, its open source model, and low cost of ownership.

Red Hat certifications are industry leading in the IT field. Exams are designed to be hands-on and performance based to ensure the most accurate, real-world environments. Red Hat customers can feel confident that they are getting the most from their Red Hat deployments because certified professionals work with customers every step of the way.
A Red Hat Certified System Administrator (RHCSA) certification is earned when an IT professional demonstrates the core system administration skills common to Red Hat Enterprise Linux environments. RHCSA is an appropriate certification for system administrators and professionals in a wide variety of related roles, including database administrators, developers, and support technicians.
Red Hat Certified Engineer (RHCE) is earned by a Red Hat Certified System Administrator (RHCSA) who has demonstrated the knowledge, skill and ability required of senior system administrator responsible for Red Hat Enterprise Linux systems.
