Red Hat Certification Guide: Overview And Career Paths. Red Hat offers certifications on virtualization, storage, cloud and the company's open source- based operating systems. This certification guide will help you get started with the popular RHCE and RHCSA as well as other Red Hat certs and career paths. Red Hat, Inc. The company has been around for over 2. Red Hat Enterprise Linux (RHEL) distribution.

Red Hat provides a fully open technology stack, which you can alter to suit your needs — you're not locked into the vendor's vision of the software. Red Hat's portfolio of products and services also include JBoss middleware, cross- platform virtualization, cloud computing (Cloud. Forms and Open. Stack) and much more. Red Hat offers a number of professional certifications based on its software products including operating systems, virtualization, storage and cloud- based solutions.

Red Hat Certification Program Overview The Red Hat certification program is aimed at system administrators, engineers, architects, enterprise developers and application administrators, as well as cloud and virtualization administrators, who use RHEL in the IT infrastructure. The program aims to ensure candidates are proficient in RHEL by requiring performance- based certification exams. Whereas many certification exams ask multiple choice or fill- in- the- blank questions about specific technologies, Red Hat requires you to perform and complete real- world tasks using Red Hat technologies in order to pass its exams. Red Hat traditionally offered certification exams only upon completion of a training course. Now you can take a Red Hat exam on your own schedule, outside of training, if you prefer. The exam session is performed on a secured system in a professionally proctored testing center.

The centers are located in select cities throughout the United States, Europe and Asia. Once you earn a Red Hat certification, you become a Red Hat Certified Professional. This gives you access to Red Hat Certification Central, which allows you to connect with potential employers, join the Red Hat community, create study groups and collaborate on projects. In addition, you can explore Red Hat's training options and easily schedule individual exam sessions. Discounts on recertification exams are offered as well. Red Hat Administrator, Engineer And Architect Certs. The largest group of Red Hat certifications is geared toward system administrators, engineers and architects.

Some of the most popular and sought- after Red Hat certifications reside in this category, such as the Red Hat Certified System Administrator (RHCSA), Red Hat Certified Engineer (RHCE) and Red Hat Certified Architect (RHCA).

RHCE: Red Hat Certified Engineer. The RHCE certification is geared toward experienced senior system administrators, and fulfills requirements of U. S. Department of Defense Directive 8. To obtain the RHCE certification, you must first become RHCSA certified. The recommended training for the RHCE certification is based on your skill level. Windows admins with minimal Linux experience should take the Red Hat System Administration I and II (RH1. RH1. 34) courses, along with the Red Hat System Administration III (RH2.

Linux or UNIX admins with one to three years of experience should take both the RHCSA Rapid Track Course (RH1. Red Hat System Administration III (RH2. RHCEs looking to recertify, or candidates who'd like the opportunity to engage in a lab- based review before taking the RHCE exam, should take the RHCE Certification lab (RH2.

The certification lab is a four day, instructor- led opportunity to work through all of the labs from the Red Hat System Administration I, II and III courses, along with the Rapid Track course. To complete the RHCE certification, you must pass the 3. RHCE Exam (EX3. 00), which is currently based on Linux 7. RHCA: Red Hat Certified Architect.

The RHCA certification is the pinnacle cert in the Red Hat Certification program. To qualify for the RHCA, candidates must possess a current RHCE or Red Hat Certified JBoss Developer (RHCJD) credential.

Depending on the concentration chosen, five or six exams are required to obtain RHCA certification. Currently, the RHCA is available in five concentrations: Datacenter, Application Platform, Dev.
