If you want to have any idea about popularity of Linux Certifications, you can have a look at a recent report of CertCities which branded Red Hat Certified Engineer (RHCE) certification exam as ‘hottest certification’ among all IT certifications. There are no Linux certifications for developers and end users and all of the four available Linux certifications focus on system administrator role. All these certifications focus on various flavors or versions of Linux.
Description: The four available Linux certifications are:
- CompTIA: Linux +
- LPI: Linux Professional Institute Certified (LPIC)
- Novell: Certified Linux Professional/Engineer
- Red Hat: Red Hat Certified Technician/Engineer/Security Specialist/Architect
Linux + and LPIC certifications are vendor neutral i.e. these are not specific to any Linux flavor. The CLP/CLE certification programs offered by Novell have focus on the SUSE distribution of Linux. As the name of the certification suggests, Red Hat Certified Technician/Engineer/Security Specialist/Architect certification focuses on the Red Hat distribution of Linux and is offered by the vendor Red Hat.
Some description of each of these certifications is provided here:
1. CompTIA: Linux +: This certification is offered by CompTIA which is a non profit organization and widely respected in the IT industry for its vendor neutral certification programs.
