At A Glance: Red Hat-Certified Engineer (RHCE)
There is a variety of software programs and applications available that provide a myriad of features and business solutions. As many different applications as there are available, there are just as many companies producing and distributing these programs. Oftentimes, these programs and applications can be integral to the way a company or organization conducts its business, but they can also frequently fall short of providing all the features and services needed — and sometimes they’ll fall out of product development cycles, leaving an organization without the software support and updates it needs. The solution to these potential pitfalls that have naturally developed in the marketplace is open-source software. Open-source software allows users access to the code and development of applications and programs, allowing for updates and alterations to be made when they are needed. One provider of open-source software is Red Hat.
Red Hat provides a variety of software solutions for all types of uses and applications. In addition to software products, Red Hat also trains and certifies professionals who are capable of quickly assessing and working with the various Red Hat products and services your company interacts with. The Red Hat Certified Engineer is a mid- to high-level professional who can help you and your company implement the open-source security and networking services of different Red Hat products. These highly-skilled professionals are available to leverage their computer expertise to help you develop customized software solutions in a cost-effective and efficient way.
