IT TODAY The Secret of LINUX SUCCESS Linux support for applications offers a compelling advantage T he benefits of the Linux* OS are well known yet frequently debated and refined. It’s stable, built for multiple users and supported for virtualization, which is important to businesses as a cost-saving technology. The OS also has great connectivity capabilities and works well in diverse environments supporting hardware and software from IBM, Microsoft*, Apple and many others. Accordingly, it continues to develop and grow. Because it’s open, you can use Linux as is or change it, yet it’s highly standardized—a seemingly contradictory statement. Joseph Gulla is the IT leader of Alazar Press, an imprint of Royal Swan Enterprises. Previously, he was an executive IT specialist for IBM. Linux runs on an amazing number of devices, including servers, mainframes, supercomputers, desktops, laptops, gateways, routers, mobile phones, tablets, audio/video devices, embedded processors and systemon-chip integrated circuits. Some of its key features, as well as IBM platform support, are summarized in Figure 1 (page 22). IBM embraces and supports Linux on its major hardware platforms. On System z* and Power Systems* servers, for example, distributions from SUSE 20 // SEPTEMBER/OCTOBER 2013 and Red Hat are featured, as many customers purchase support packages from these suppliers to manage their risk. Other distributions are also available. In addition to support on IBM hardware, extensive software backing is provided, offering a vital and compelling ecosystem. It includes many types of products that put Linux into action, such as database management, application servers, messaging, portals, software development and lifecycle management. Also included are systems, network and application management, human collaboration, business intelligence and data warehousing, and a variety of industry-specific solutions. Table 1 (page 22) shows this software support, with a few examples, from Power Systems and System z platforms. Analyzing applications is important in evaluating the OS’s capability to meet the needs of a diverse community of users. Over the years, Linux has grown from a good value to a great one, in large part because its support for
