Linux certification is necessary to demonstrate proficiency in the system, but there is no industry standard. Research certifiers before taking tests, and consider specific software developer certifications like RHCE. Linux is used in various devices and infrastructures worldwide.
To receive Linux certification, you must start by securing the knowledge you need to pass the Linux certification exams. You will need to take some sort of exams or certifications depending on the type of certification and experience level you want to establish. They are offered by a number of different vendors, although you should try to ensure that you are testing with an established and respected group in the information technology (IT) industry. Once certified, you can use it on your resume, often as a way to demonstrate an established standard of knowledge and performance.
Linux is a system of free software programs and projects that are developed and used by thousands of users around the world. It is a UNIX-based system and can often be found in many major network infrastructures such as Internet networks and major server configurations. Linux itself can be used on anything from small personal devices like cordless phones and digital watches to major supercomputers and mainframes.
To establish one’s Linux proficiency, most people undergo some type of Linux certification that gives prospective employers an idea of how much training or understanding one has of Linux. The main problem with this, however, is that there is no single industry standard on what it takes to achieve Linux certification. This means that simply having certification is often not enough; as many people may be certified by a disreputable group or simply claim they have the certification without actually being able to back it up.
To get Linux certified and ensure you don’t waste your time or money on a certification that won’t be respected or demonstrate real knowledge, do some background research on any certifier before paying to take the tests. You can take the tests online, but some certification centers require in-person tests to prove that you are the one taking the exam. The Linux Professional Institute (LPI) is a group that strives to provide competent testing and authentic Linux certification.
You can also look into specific software developer certification, such as the RHCE (Red Hat Certified Engineer) certification offered by Red Hat Inc. These types of Linux certifications may cost more than others and may be limited by affiliation with a large company, but they can also provide some perks such as brand recognition and established industry standards. Receiving your Linux certification can also be a big investment, as full certification can require multiple tests at multiple levels.
