Linux & Unix

“Linux was regarded alternatively to proprietary Unix. But RHEL changed it to becoming an option to Windows Server.”

In the early 1990s, after Microsoft’s famed divorce from IBM, the software company decided to go it alone and develop its operating system.

But as PC processors became faster and Intel’s first proper 32-bit processor, the 80386, found success, Microsoft embarked on a job to enter into server computing, the domain of the Unix machines.

But as it became more sophisticated, a growing number of device driver software was needed to join sound cards, display adapters and network ports. And all of this applications needed support.

“Microsoft did a very good job on certification,” he said.

Likewise, firms like Red Hat and SuSE created Linux supplies, which were certified to run on specific hardware.

One of the reasons that companies jumped in was because Red Hat made a range of certified devices. With no world of open source and Linux, we’d not have the type of scale to run a cloud. While many supporters contend that price should not function as the primary reason for selecting open source, Percival said: “Imagine trying to use a Tandem NonStop system to run Netflix. You’d never manage to purchase it.”

In the past, a premium server like NonStop would be used when extremely high availability was a precedence. Such systems were very pricey. Today’s IT architectures achieve high availability at a reduced price point by using large numbers of commodity Linux servers instead of one exceptionally bouncy carton.

So, for the business, Linux has provided a low-cost base platform on which to run big net applications, largely alternatively to proprietary Unix systems.

In a blog post earlier in 2013, Forrester analyst Richard Fichera described how hot patching was now available on SuSE Linux, giving the OS a level of maintainability usually available only on mainframe systems.

  • In the post, he predicted this would become a normal characteristic of the Linux kernel. “It is nearly certain that a future launch of the 4.x kernel will comprise production-prepared hot patch as a normal attribute, placing the weight on the Unix providers to prove they are able to stay informed about Linux,” he said.
  • According to Fichera’s site, neither Oracle (with Solaris), IBM (Aix) or HPE (HP UX) have developed same capabilities in their respective variants of Unix.

This really is something that Linux distributor Ubuntu continues to press, said Jane Silber, CEO of Canonical, which supports Ubuntu. “While the cloud runs almost entirely on Linux, we believe the desktop remains an important focus for Linux initiation, too,” she said.
