Companies are under increasing pressure to “do more with less”, prompting IT professionals to continually look for a low-cost, open platform with broad hardware and application support. Let’s compare the most popular operating systems, Solaris 10™ and Red Hat® Enterprise Linux® on key Points of Interest—designed to help technical professionals make the operating system choice appropriate for their environments.

 

There are a number of Linux and Unix operating system platform choices available today for enterprise workloads, an advantage which gives IT executives flexibility and reduces vendor risk. However, this choice also requires careful examination to select the best option among the wide range of proprietary Unix and open source Linux offerings. One of the most debatable topics today is choosing between Linux and Sun Microsystems, Inc.'s Solaris.

 

Both these platforms seem similar – both may be obtained for "free," both enjoy good availability of support offerings and administrator skills, and both are widely supported by application vendors. However, it is believed there are important differences in vendor and community strategies, market position and direction, and technical features that IT executives should consider when comparing these two options.

 

Linux is a better choice for environments where commercial Solaris is not absolutely required, including new workloads, workload migrations, and hardware virtualizations and consolidations. In any environment that can benefit from hardware flexibility and the ability to choose among multiple distribution and support vendors for a product, Linux provides a number of advantages, and it is believed that it describes most enterprise IT departments.

 

The popularity of both Linux and Solaris has ensured ready availability of skilled administrators for both platforms. Because of Solaris' earlier entry into the market, there are more "senior" level administrators available in the U.S. However, costs are still measurably higher for Solaris administrators than for Linux. Equally important, Solaris does not share the same level of popularity as Linux among younger candidates entering IT departments, such as recent college graduates.

 

Linux is a better choice for a wider mix of workloads, hardware architectures, and administrator skill sets. Flexibility is crucial in an enterprise IT department, and Linux provides more choice of hardware, distribution models, and support providers without effecting how it is administered or the applications it may run. This allows IT executives to select hardware to match a workload, knowing that it will almost certainly be supported by Linux. Solaris is available on a variety of platforms, but still lags behind Linux in this area.

 

Experience with Linux+ and a Linux certification can provide better IT positions for professionals, as well as building their knowledge within a framework that is vendor neutral.

 

As the demand for skilled professionals who can work to the advantage of their organization by exploiting this powerful platform is increasing, the benefits of Linux training and certification are obvious.
