No matter how top notch equipment or software is, it is only as good as the people behind it. With this in mind, we are launching a series that evaluates the skills to successfully manage various operations or functions within the server room. We will look at the most sought-after skills and certifications to aid both those in the hiring seat and those trying to be hired — whether just starting out or making a career switch.

No matter how top notch your equipment or software is, it is only as good as the people behind it. Our newest series looks at the skills needed for a successful server room. We kick it off with an overview of what it takes to be a Web server or app server admin.

The field of Web and application server administration is broad and amorphic. Its tasks and responsibilities vary widely from one organization to another. Unlike becoming, say, a doctor or a lawyer, there is no single defined path into the profession. This is partly because the Web server industry has only recently begun to mature, and universal standards and expectation have yet to be set, and partly because successful Web administrators can come from a variety of backgrounds: Some have formal education with specific certifications, while others have been informally educated but bring with them much experience and enthusiasm.

Depending on the organization, its IT infrastructure, needs, and resources, administering the Web or application server may be only a small part of a larger network administration role. Or it may be a central responsibility.

Clearly, Web servers aren't going anywhere any time soon. As the Internet has evolved, the demands placed on Web servers have grown significantly — and not just in terms of sheer traffic volume. As uses for the Web mature, what were formerly referred to as Web pages are quickly morphing into what is better described as Web-based applications. Traditional Web servers simply handed static pages from server to client. The new generation of application servers perform sophisticated server-side processing — constructing pages rather than merely acting as a simple intermediary — and are a completely different animal to tame.

Depending on the organization, its IT infrastructure, needs, and resources, administering the Web or application server may be only a small part of a larger network administration role. Or it may be a central responsibility.

Two Worlds

Very broadly speaking, server environments are divided into two camps: Microsoft shops and Unix-based shops. The former use Windows, while the latter use a variety of operating systems, such as Solaris, Linux, and BSD. Many organizations have invested in one or the other or, less frequently, a mixture of Windows and Unix. Such heterogeneous networks are becoming more common as organizations grow larger and develop more layers.

We all know the caveats about stereotypes. That said, Microsoft and Unix systems tend to attract different cultures which may, in turn, involve different sets of expectations from current and prospective employees. Microsoft-based shops, for example, may conform more closely to the "corporate culture" environment, with employees expected to participate in structured professional development, including certifications and ongoing training. Unix shops are more likely to attract IT professionals drawn from an "enthusiast" background, and may place a higher value on informal, self-taught, hands-on experience over structured, formal education.

Like all generalizations, these are not hard and fast rules but general trends. Exceptions are present in both environment.

Get Certified?

The importance and usefulness of technical certification in server administration is the subject of much debate. It is a simple fact that certification is big business. Dozens of companies sell certifications through course work, exams, or a combination of the two. Some certifications require annual renewal to remain valid, which may or may not involve additional testing, and almost always involves additional costs.

Many veteran server admins place a lower value on certification, per se. They believe hard-earned experience in the trenches is a more valuable employee asset than passing grades on exams. On the other hand, as the industry matures and the candidate pools grow, certification becomes an increasingly important way for human resource departments to separate some applications from others and gives hiring managers objective benchmarks.

Certification can be a useful way to get noticed, particularly when pursuing work at large organizations. It is also a useful, although potentially costly, way to fill in knowledge gaps — even for those with experience. For many IT managers, however, experience and enthusiasm will be the ultimate factors in evaluating a candidate.

The chart below highlights some of the well-known certifications in Web and application server administration. Some are vendor-specific; for example, the Microsoft and Oracle certifications are particular to their respective products. In all cases, the total costs of certification may exceed the exam costs themselves. For example, a training program to learn the material may involve tuition, materials, and travel and lodging costs. Also, some certifications may require prerequisite exams.
