These embedded application clouds will require local points of presence POPs or on-site infrastructure and hardware rolled into service level agreements SLAs supporting the software and service delivery portions of contracts.

VDC Research's surveys of hundreds of OEMS across a number of embedded markets reveal significant growth in OEM plans to develop solutions on hybrid platforms incorporating two or more of these technologies. Even if the market does not return to pre-recession levels, growth will accelerate during VDC sees virtually every vertical market growing more than five percent, and most technology categories achieving the same five percent CAGR.

However, profitability results may not be so positive. Demand for stable technologies, brutal price concessions and expanded services requirements will provide opportunities for differentiation and revenues, but not necessarily margin. Android to catalyze further growth in commercial Linux market. As device manufacturers take Android into new application classes beyond mobile, the commercial Linux market will experience further growth.

More application classes will have sophisticated UI functionality that is not supported by traditional OSs and end-users will seek out multi-OS systems. Driven by hardware bill of materials savings and reduced concerns regarding additional run-time execution latencies and costs, operating system virtualization will provide increased growth opportunities, and therefore will continue to be a significant focus for many suppliers.

Intel's increasing focus on embedded combined with Symbian's loss of strategic direction will drive additional gains for MeeGo as Nokia turns their attention toward the Linux-based platform. Increased interaction with the cloud and web-based content by more embedded device classes will increase OEM focus on use of web security test tools.

The increasing burden of mobile device data usage is driving the need for investment in wireless infrastructure and the telecom vertical market will reaccelerate spending on commercial products. Riding the wave of Windows Phone 7 buzz, Microsoft will re-emerge as a leading player in the mobile phone arena.

Embedded Linux is the use of Linux in embedded computer systems such as mobile phones, personal digital assistants, media players, set-top boxes, and other consumer electronics devices, networking equipment, machine control, industrial automation, navigation equipment and medical instruments.

The advantages of embedded Linux over proprietary embedded operating systems include no royalties or licensing fees, a stable kernel, a support base that is not restricted to the employees of a single software company, and the ability to modify and redistribute the source code. The disadvantages include a comparatively larger memory footprint kernel and root file system , complexities of user mode and kernel mode memory access and complex device drivers framework.

There are non-proprietary embedded operating systems that share the open-source advantages of Linux, without the memory requirements that make Linux unsuitable for many embedded applications.
