The server OS: Present and future trends research has provided some interesting insights about how server operating systems and management are developing

What is the state of play when it comes to the development and management of server operating systems, and how is the landscape likely to change in the future?

According to a survey carried out by, the bottom line is that Linux and Windows are the prevalent platforms for the majority of companies and will take more market share from Unix in the future.

The survey also reveals that one of the most hyped technologies of the moment — virtualisation — is arguably still being talked about more than it's being employed, while cost and complexity mean that the server operating system (OS) as a 'plug and play' technology is still more aspiration than reality.

Compiled in May 2008, the research was based on responses from 195 readers. Respondents came from a variety of organisations, from small firms to large enterprises.

One of the main findings from the survey is that, if current trends continue, servers running anything other than Red Hat, Novell Suse or Windows Server will become increasingly rare. A clear majority of those surveyed, 81 percent, ran Windows Server, with Linux (of the Red Hat or Suse flavours) the next most used OS, at 50 percent. It is important to note, however, that the majority of respondents ran multiple operating systems, with 44 percent using only one server OS.

The survey provides an interesting counterpoint to other research in this area, according to analysts. "Though there are some interesting differences with our findings, this survey does seem to be a pretty good reflection of how we see server usage," says Chris Ingle, consulting and research director for systems at analyst group IDC.

One of the major findings of the research is that, in terms of importance to system managers, virtualisation was bottom of the list of server OS features, despite considerable hype around the technology. Far in front, in order of criticality for this group, were scalability, high reliability/failover, identity management and aggregation and account management.

However, when asked "What plans do you have for your servers in the next five years?", 'consolidation and virtualisation' emerged as the top answer, ahead of being 'green' and increased uptake of dual-core hardware.

"We found it interesting that nearly a third of respondents said they had plans to start virtualising their servers in the next five years, despite saying it was currently low on their priorities," says Gareth Hall, Microsoft's Windows Server product manager. "This suggests that we are beginning to see a change in attitude, with more people considering virtualisation as a sensible way to increase existing server productivity and cut costs."

In terms of IT budget, the financial resources of the respondents closely matched the budgets that would be expected for small firms and large enterprises. At the lower end, 23 percent of respondents said they had IT budgets of up to £10,000, while 20 percent said their budgets were between £10,000 and £50,000. Larger budgets were also represented, with 10 percent of respondents claiming IT budgets of greater than £10m. The mid-range perhaps found less representation here than in comparable research, as only 17 percent of respondents reported IT spend of between £100,000 and £500,000.

Respondents were mainly technical professionals working with servers every day. Twenty-three percent said they worked as IT consultants and 17 percent as network or systems administrators. These roles were followed by support, developer and project-management job functions.

The findings also showed that IT professionals are still struggling to get what they want from their servers. Asked what the main 'pain points' were for professionals working with server operating systems, respondents' replies included: "no standard management interfaces for [working with] mixed OS", "cost" and "unreliability". In fact, cost came up as the number-one issue in the majority of free-form responses (where people were not responding to a set question but offering their own, additional comment). Ease of management also proved an important issue, with one respondent claiming: "The level of expertise required to manage a simple [Microsoft Windows Small Business Server] server is dreadful".

The survey also contained some findings that, on first reading, seem unfavourable to server OS market leader Microsoft. According to the survey, only a minority of respondents have plans to migrate to Windows Server 2008 in the near future. When asked about their deployment plans in this area...
