Snapshot of the embedded Linux market — April, 2007

Apr 26, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 19 views

The results of LinuxDevices.com's seventh annual Embedded Linux Market Survey are in! This brief summary outlines our interpretation of a few key data points. Overall, we find the results encouraging for embedded Linux, and for companies in the embedded Linux OS and tools market.

This year, our survey drew 932 respondents, or 79 more than last year over a comparable period of time. This alone shows that interest in embedded Linux continues to grow, a fact also reflected by the growing readership of our Website and opt-in newsletter.

As we do every year, we encourage readers to draw their own conclusions from the complete survey response data. Last year's (2006's) summary findings are also available for comparison, along with detailed response data from years past.

Please note that while we make every effort to increase result validity by limiting responses to a single submission per IP address, respondents are self-selected, and we have minimal control over multiple or dishonest voting. Also, our market share results are not meant to reflect upon the commercial success of individual companies. For commercial marketshare figures, LinuxDevices.com recommends VDC, EDC, IDC, ABI, and Gartner, among other capable sources.

And now, our latest observations . . .

Linux adoption just keeps on increasing

Linux has truly established itself as a viable if not dominant embedded operating system that is used in thousands of new designs each year. Our survey results over the past four years show that Linux adoption is still on the rise, although uptake has certainly slowed since the “boom” years in the early part of the decade. This year's survey results suggest that 49 percent of our survey's respondents have used Linux in embedded projects and/or products — a growth of about two percentage points over last year's results.

Our survey results suggest that while Linux continues to gain popularity, most traditional embedded OSes and RTOSes (real-time operating systems) may be losing marketshare. Other than Linux, every other RTOS or OS declined significantly, remained flat, or gained only a statistically insignificant amount.

When will Linux's embedded momentum peak?

Each year, we ask about planned OS use over the next two years, as well as actual OS use over the previous two. In the early days, planned use far surpassed actual use. Today, as more and more project teams succeed in executing their Linux migration strategies, the Linux “uptake gap” has narrowed dramatically. Trend lines on the chart below suggest that by 2012, actual and planned Linux use will converge, at about 70 percent.

Interestingly, last year's survey data suggested that embedded Linux's uptake gap would close between 2009 and 2010 at closer to 60 percent. However, some 61 percent of this year's respondents plan to use Linux within two years, compared to 58 percent in the past two years — an increase that suggests Linux adoption may not level off as quickly as previously believed, and may achieve a greater overall market penetration than originally thought.

Commercial Linux on the rise

Last year, we found the single most significant trend in our survey data to be a large increase in respondents' willingness to pay for embedded Linux development and support services. That trend held steady this year, as once more, about two thirds said they would definitely consider buying support/services.

Yet, only 22 percent of respondents reported actually purchasing commercially supported embedded Linux distributions, as indicated in the chart below. Commercial distributors may have far to go before tapping the market's full potential.

That said, the number of respondents who said they purchased their Linux distributions actually grew by about 19 percent compared to last year. Thus, commercial Linux distributors do at least appear to be on the path toward growth.

Additionally, results from our survey's question about planned sources of Linux augurs more growth ahead for commercial embedded Linux providers (see chart below).

Commercial tools opportunity also growing

This year's survey data also suggested that more of our readers expect to use tools supplied by commercial Linux vendors, while fewer will use tools from specialized tools vendors, such as RTI and SlickEdit. This result echoes a similar finding from VDC, which in September predicted essentially flat market growth for “unbundled” tools.

Community-supplied tools, such as vanilla Eclipse, OpenEmbedded, and GNU tools remained the top choice among survey takers. While Eclipse rated last in user satisfaction on an Evans developer survey from last year, our survey respondents — many of whom likely use Eclipse — were generally pleased with tool quality, with all but about 10 percent rating their tools “very good” (28.7 percent) or “acceptable” (55.7 percent). This may reflect the considerable work done by Linux suppliers to adapt the Eclipse framework to device development.

Legal sophistication increasing

Responses to this year's survey suggest that LinuxDevices readers may be becoming more sophisticated in their understanding of legal risks and responsibilities associated with free software. Fewer reported relegating due diligence to developers, while more reported having actual lawyers perform due diligence. Additionally, slightly more readers than in the past said they were covered by insurance or indemnification from their software vendor.

Furthermore, respondents this year worried less about specific legal threats to Linux than in the past. Patent concerns fell sharply, as did concerns about SCO. Copyright concerns grew only slightly. The largest group of respondents — 44 percent — reported no concern over the specific threats we asked about.

Sources of embedded Linux remain diverse

Each year, we try to identify the most popular commercial and non-commercial sources of embedded Linux among our readers. This year's results suggest that little has changed since 2005, when we wrote:

Taken as a whole, the embedded Linux landscape seems most noteworthy for the large variety of popular sourcing options, rather than for the dominance of any single vendor or organization. This suggests that Linux continues to deliver on the promise of vendor neutrality and absence of vendor lock-in, and that embedded Linux technology remains adequately decoupled from the fortunes or failings of any single company or organization.

That said, a few distributions fared especially well in this year's survey results, compared to last year. Ubuntu, which we asked about for the first time, debuted with a near six-percent marketshare, suggesting that many embedded developers like to take advantage of the pre-integration offered by popular desktop Linux distributions.

Debian remained the most popular distribution overall, while Red Hat and Fedora both lost marketshare among survey respondents, compared to last year.

Among commercial embedded Linux distributions, MontaVista remained the top vendor, despite dropping a couple of percentage points. This year, 5.5 percent of respondents reported using MontaVista, compared to about 7 percent last year.

European Linux distributors Sysgo and Koan both grew strongly. Sysgo more than doubled in reported usage, growing from 1.2 to 2.9 percent of respondents, while Koan was reportedly used by 4.1 percent of survey takers, up from 2.9 percent last year. Denx usage dropped very slightly, however.

ARM still top architecture

Three years ago, ARM displaced x86 as the embedded architecture our readers reported deploying most often. This year, ARM once again proved the heavyweight, reportedly used by 30 percent of readers, with a full third expecting to use the architecture within the next two years.

Looking at reported architecture usage over the past four years (chart below), ARM's leadership position in the embedded market appears to be fairly well established, with the relative positions of other embedded processors also remaining about the same.
