Data shows down economy spurs Linux adoption

A Novell-sponsored IDC survey reveals a surge in the acquisition of Linux driven by the worldwide recession. More than half of the IT executives surveyed are planning to accelerate Linux adoption in 2009. If that’s not positive enough, more than 72% of respondents reported that they are either actively evaluating or have already decided to increase their adoption of Linux on the server in 2009, with more than 68% making the same claim for the desktop. The study surveyed more than 300 senior IT executives spanning manufacturing, financial services, and retail industries across the globe, as well as government agencies. The survey results are a good update to the fall 2008 Purchasing Intentions survey we conducted that hinted the economy would impact Linux adoption.

Linux has been gaining ground in the enterprise, as was seen with Red Hat’s impressive results from 2008. We said back in January that open source would do well in a down economy, and now there’s data to back up the prediction.

In the IDC survey, the leading reason given for migrating to Linux was an interest in lowering ongoing support costs. More than 40% of survey participants said they plan to deploy additional workloads on Linux over the next 12-24 months and 49% indicated Linux will be their primary server platform within five years. (Is anyone else surprised by that number?) Among those hesitant to adopt Linux, lack of application support and poor interoperability with Windows and other environments was cited as the primary concern, indicating the key areas that need more work. Companies have made great strides where interoperability is concerned, but clearly more work needs to be done before Linux can gain more ground. We have covered Red Hat’s recent interoperability agreement with Microsoft, Canonical’s effort’s toward certification on HP servers, and reviewed the leadership of Novell in interoperability efforts. But, clearly the market needs more assurance that Linux will meet their critical business needs.

Key to the recent interoperability efforts has been virtualization. This is a good move according to the survey results as nearly half of respondents stated that moving to virtualization is accelerating their adoption of Linux. A notably high, 88% of those surveyed plan to evaluate, deploy or increase their use of virtualization software within Linux operating systems over the next 12-24 months. An increase in virtualization uptake was seen in our 2008 Purchasing Intentions survey, which revealed that virtualization interest was influencing server purchases.

In our recent newsletter, we asked readers to tell us what’s missing from all of these agreements. We encourage you to share your thoughts here. What would you like to see in terms of specific application support or capabilities? What’s missing from the interoperability landscape?

Zimbra tops Google’s Gmail with 40 million paid mailboxes

It’s impressive to be able to give away 31.2 million free Gmail accounts, as Google has. It’s even more impressive to get customers to pay for 40 million mailboxes, as Zimbra reported today, representing a sharp spike from the 20 million paid mailboxes reported in early 2009.

The secret to Zimbra’s success? Innovation and integration, in part. While Google Maps has found its way into a range of different applications, Zimbra leads Gmail in mash-ups (called “Zimlets” in Zimbra parlance). My company is a Zimbra customer, and one of our sales engineers wrote a Zimlet to integrate Alfresco with Zimbra…in his spare time…over a weekend.

Yes, Zimbra is that easy to extend.

As for innovation, as just one example Zimbra beat Gmail to offline application access by two years. Not bad for a company with a fraction of Google’s employees (or PhDs).

As VentureBeat points out, Zimbra is now ahead of Gmail in unique mailboxes and only slightly behind Microsoft’s Hotmail service. That’s pretty impressive: one little open-source company takes on the two titans of software and wins (against Gmail), or shortly could win (against Hotmail).

Yes, the jump from 20 million to 40 million is likely due to Comcast’s decision to use Zimbra for its user e-mail accounts. But it’s still impressive.

Frankly, it’s a shame that Zimbra ended up with Yahoo, which has 92.5 million mailboxes. Though Zimbra is a standout in the industry, Yahoo’s own strength in consumer e-mail likely keeps Zimbra in second place for resources internally, especially since Zimbra’s enterprise-grade e-mail may not be a tight strategic fit. Zimbra would have been an exceptional match for Apple or Adobe with their design-savvy customer bases.

What’s done is done, however, and Zimbra will just have to settle for getting 40 million paid mailboxes while others can hardly give that many away for free. It’s a tough job, but someone has got to do it.

UPDATE: I should have pointed out that the Gmail numbers relate to U.S. totals. It wasn’t my intent to mislead on that; I simply failed to call it out, and apologize. Also, as pointed out in the VentureBeat story, to which I linked, none of the numbers – Google’s or Zimbra’s – are absolutely to be relied upon, as ComScore numbers can be inaccurate and Zimbra’s are self-reported. Even so, Zimbra’s progress is impressive.

A commentator below rightly points out the difference between active users of a service and the raw number of mailboxes sold (in Zimbra’s case). This is a useful, but not dispositive, point. If anything, it probably affects Gmail’s reported numbers more negatively than Zimbra’s.

At any rate, which problem would you rather have: paid but inactive users or freebie inactive users? I’m guessing that Zimbra will happily take the former, and work to innovate more to turn passive accounts into active users; otherwise, Comcast and other customers simply won’t renew their subscriptions.

As for the source of the 20-million user jump for Zimbra, some of this comes from bring the Comcast users online with Zimbra. Zimbra announced the deal in 2007 but that there’s a big time gap between closing a deal and deployment.
