Gastkommentar: Linux verdrängt UNIX

Das technologisch innovationsfreudige Linux verdrängt langsam die klassischen UNIX-Systeme.

Brian Cornell ist Senior Regional Director und General Manager Central Europe bei Red Hat.

In basement 90er Jahren galt UNIX als aufstrebender Stern. Viele Unternehmen setzten nicht länger auf Mainframes, sondern auf eine vergleichsweise günstige, performante und zuverlässige Alternative. In der Zwischenzeit verdrängt das technologisch innovationsfreudige Linux die klassischen UNIX-Systeme.

Beispiel gefällig? Laut der im Juni 2013 veröffentlichten Liste der schnellsten Supercomputer der Welt liefen 95 Prozent unter Linux. Zwanzig Jahre zuvor dominierten UNIX-Systeme die Liste.

Auch in basement Unternehmen setzt die Abkehr von UNIX langsam ein. Viele hatten eine umfangreiche und langjährig genutzte Infrastruktur aufgebaut, deren Lebenszyklus sich nun dem Ende zuneigt. In naher Zukunft laufen die Wartungsverträge für die UNIX-Server aus. Jetzt ist es daher höchste Zeit, sich mit Alternativen zu befassen, ansonsten laufen Unternehmen Gefahr, dass sie basement richtigen Zeitpunkt verpassen.
 
Es gibt gute Argumente für basement Wechsel. Die IT disorder immer höhere Anforderungen bewältigen, was mit einer nicht mehr aktuellen UNIX-Infrastruktur nicht gelingt. Wenn es um die Modernisierung der IT geht, die Geschäftsziele effizienter als bislang unterstützen soll, sind Server- und Applikationskonsolidierung gefragt, verbunden mit der Virtualisierung von Rechnern und Speicherpools. Linux bietet hier im Vergleich zu UNIX die bessere Virtualisierungseffizienz. Gleichzeitig haben es Unternehmen dann leichter, gleich oder zu einem späteren Zeitpunkt in eine Private oder Hybrid Cloud zu migrieren.

Kosten sparen ist einer der wichtigsten Gründe für eine Migration. Bei der Evaluation einer Alternative zu UNIX sollten Unternehmen nicht nur die Beträge für basement Hardware-Kauf, sondern auch die damit verbundenen Lizenz-, Verwaltungs- und Wartungskosten berücksichtigen. Die Praxis in vielen Unternehmen bestätigt: Proprietäre UNIX-Systeme binden erhebliche materielle und personelle Ressourcen, da sie einen hohen administrativen Aufwand erzeugen. Unternehmen werden darüber hinaus abhängig von einem einzelnen UNIX-Anbieter.
 
Linux dagegen folgt offenen Standards und profitiert von einem Community-getriebenen Ansatz bei der Entwicklung innovativer Betriebssystem- und Virtualisierungstechnologien. Unternehmen werden unabhängig bei der Kombination aus Hardware und Betriebssystem. Statt teurer UNIX-Rechner genügen kostengünstigere x86-Systeme. Unter dem Strich profitieren Unternehmen mit Linux von einer hohen Leistung, Verfügbarkeit und Skalierung bei gleichzeitig niedrigen TCO-Werten. Einer der wichtigsten Vorteile: Mit Linux wird die IT effizienter.

REALTECH AG : REALTECH releases new whitepaper about a trend from … – 4

Linux offers a best cost opening ratio in a market
Even if we only review matching server classes (e.g. four-socket-servers), servers using 64-bit X86 CPUs offer adult to a twenty times improved value than allied UNIX ones. The whitepaper demonstrates that only by relocating to Linux and x86_64, one of REALTECH’s emigration business lowered their SAP server costs by over 80%, while during a same time during slightest tripling their accessible SAP computing power.
All in all, a 64-bit X86 XEON processor from Intel seems to have a best brew of best environmental and opening qualities in courtesy to SAP applications and a whitepaper will explain why. To do so, REALTECH evaluated some-more than only a price/performance ratio, though also looked into technical qualities of a processors on a opening per socket, per core and per thread basis.

Linux but limits
The investigate also gives discernment on a extent distance of singular SAP systems and altogether complement landscapes that can run on Linux, as good as a extent distance of emigration plan that can be done. It demonstrates that there is no attestable extent for a distance of an SAP complement or database on Linux, as good as if approached in a right approach there is no distance or criticality of customer, plan or landscape that can't be remade from UNIX to Linux. To be successful in a emigration project, we need to equivocate visit and standard mistakes. The whitepaper explains a keys for success in detail.

“It is transparent to see from this investigate that Linux is now a elite choice for UNIX emigration as it is a proven height for goal vicious SAP applications and offers a fortitude and accessibility required during a most reduce cost point,” pronounced Naji Almahmoud, comparison executive of tellurian business development, SUSE. “What’s more, SUSE Linux Enterprise Server for SAP Applications clearly offers business some-more by including a High Availability Extension and other program and services privately designed to accommodate a needs of SAP users.”

Summary
Altogether, a trend investigate clearly shows that Linux and a x86_64 CPU design have arrived in SAP information centers as a mainstream solutions with a by distant best price/performance ratio, and that they are excellently matched to broach complement landscapes of both high opening mandate and high criticality. The whitepaper will explain because business watchful too prolonged with a deputy of cursed UNIX architectures competence get into trouble, and that it is time to act now.

IDC: Linux drives datacentre server shipments

The latest marketplace share information from IDC shows that Linux is fuelling a swell in direct for server
hardware.

According to IDC’s latest EMEA (Europe, Middle East and Africa) Server Tracker, Linux was
the usually handling complement to knowledge certain expansion year on year, adult 6.5% during $750m, or around
20.7% of sum marketplace sales. 

The initial entertain of 2012 was a second time that Linux overtook Unix in marketplace share since
records began. The initial time this happened was in a third entertain final year. 

Unix declined 27.6% on a behind of weaker Risc complement sales, with sales of $542.4m. Windows held
52% of a market, generating hardware spending of around $1.6bn, down 0.6% year on year. Of the
main handling systems, usually z/OS declined faster than Unix, by 39.3% to strech $201.9m.

Giorgio Nebuloni, comparison investigate analyst, craving server group, IDC EMEA, remarkable that cloud
providers were pushing sales of density-optimised servers. 

“EMEA datacentre comforts are increasingly underneath vigour to broach forlorn power
density on a per-rack and per-square-meter basis,” he said.

The IDC marketplace information showed that x86 income reached $2.2bn, homogeneous to 73% of a total
market, a decrease of 3.4% annually. This was a 13th uninterrupted entertain in that x86 sales
surpassed non-x86 servers, as a marketplace trend towards industry-standard servers
consolidates. 

Epic (Itanium) servers gifted a sharpest tumble in non-x86, down 46.5%, followed by Cisc
and Risc systems, down 34.3% and 16.8% respectively. Risc income reached $451.8m, or 14.5% of the
market, while mainframe sales reached $263.1m, or 8.4% of sum EMEA sales.

 







Is Linux prepared for your PC?

In a conflict of a desktop handling systems (OS), there are customarily 3 widespread players left – Windows, Mac and Linux. At some point, Windows was expel as a height for a common man, Mac as a one for a artist, and Linux as a geek’s playground.

Linux found foster in powering servers, supercomputers, vast businesses and even batch exchanges. And Google even used it as a height to build a renouned Android mobile handling system. But in a desktop and cover space, it still unsuccessful to benefit traction.

There’s an picture compared with Linux that can be frightening for a normal user, invoking cinema of authority lines and depot windows. But over a past 20 years, some large stairs have been taken to make a OS some-more accessible.

The Linux desktop

Linux comes in some-more flavours currently than what we would find in an ice cream shop. Each flavour, called a ‘distribution’ or ‘distro’, is designed for a opposite set of users. Some of a many renouned ones are Ubuntu, Fedora, Mint, OpenSUSE, Debian and CentOS.

Each distro has a possess unique, discerning and easy to use interface, designed following pointy user testing. Developers have delicately complicated what stairs people take for common day-to-day tasks and have finished poignant improvements to facilitate as good as speed adult a user experience. Still, behind all a eyecandy lies a same fortitude and coherence that creates Linux a OS of choice for companies like Google, Amazon and eBay.

Distros use opposite interfaces, giving a extended accumulation in demeanour and feel. Popular ones are Unity, Gnome or KDE, that work best if your complement has 512MB RAM or higher. If we are regulating an comparison PC or enterprise faster speeds, interfaces like LXDE or Xfce are a approach to go.

Each distro is open source and a applications are grown by a village of enthusiasts. This customarily translates into a engorgement of singular facilities and add-ons that make computing many easier. For example, if we have thousands of MP3 files on your tough drive, an focus called Nautilus – a record path-finder – lets we reason your rodent over a record for a few seconds to automatically play a track.

Similarly, those who adore present messengers and use mixed ones – Yahoo Messenger, ICQ, Windows Live or Google Talk – competence infrequently be stormed by a flurry of messages popping adult together. In Linux, if we accept 5 messages, they all lay in a summary queue. The initial one shows adult in a presentation area, fades out, and a subsequent one fades in. The Empathy Instant Messaging customer supports all a renouned discuss applications, including Facebook chat, so we need customarily one module to bond to all your favourite discuss services.

Apps: work play

Initially, Linux users face a vital problem in anticipating module for any distro, as good as installing it. But all that has altered recently. One of a things that mobile users suffer many is a ability to learn and implement applications from their phone’s app store. Similarly, Linux desktops also have app stores, such as a Ubuntu Software Center and Deepin Software Center, that offer thousands of giveaway and paid module for gaming, education, capability and development.

But will Linux be excellent for your common computing needs? On a work front, it’s adult to speed. For all bureau applications such as word processors, spreadsheets and presentations, many distros come with an bureau apartment pre-loaded, such as LibreOffice, OpenOffice, or Calligra (or we can download them if not pre-installed). These can simply open many MS-Office files, be it one finished in a latest MS Office 2010 or comparison versions. They can also save files to a same formats, as good as others such as PDF – ideal if we wish to send an check to someone but permitting them to revise it.

The customarily thing missing is an email apartment to take on a absolute Microsoft Outlook. But Mozilla’s Thunderbird supports Linux and is some-more than able of executing anything we would have finished in Outlook.

There’s no necessity of games accessible either. Popular titles such as Battle for Wesnoth or OpenArena will let we while divided some time. And hey, what’s a mechanism but Solitaire? The world’s favourite digital label diversion and a twin FreeCell are both accessible on Linux, as good as Tux Math – a fun diversion to keep your mathematical skills sharp.

You can play song in a far-reaching accumulation of song players available, and also revise your marks regulating Audacity. There’s also a ability to revise videos with Shotwell, and a famous VLC actor can play many audio or video files. And of course, a Gimp picture editor will make we never skip Photoshop again.

In many cases, if we consider we need a module for something, afterwards chances are that it’s accessible for Linux – and now it’s easier afterwards ever before to find it.

Secure and updated

One of a vital attractions to Linux and open source is that a module has no viruses, expelling a headache of your PC going down each few months, or of shopping costly antivirus software.

“There are about 60,000 viruses famous for Windows, 40 or so for a Macintosh, about 5 for blurb Unix versions and maybe 40 for Linux. Two-three of a Macintosh viruses were widespread adequate to be of importance. None of a Unix or Linux viruses became widespread – many were cramped to a laboratory,” write Dr. Nic Peeling and Dr Julian Satchell in their news patrician Analysis of a Impact of Open Source Software.

Linux also doesn’t delayed down over time; it runs during a same speed as when it was initial installed. And what’s maybe some-more critical is that a applications theoretically won’t hang your whole system. If some module misbehaves, customarily that focus hangs but inspiring other things.

Linux also gets absolved of those consistent pop-ups seeking we to refurbish a module or implement drivers each time we run it. The complement manages all updates centrally, so we customarily have one focus that prompts we for a upgrade. And it’s customizable adequate that we can make it automatic, ask for a presentation but a pop-up, and even spin it off entirely. It creates for a clutter-free and undeviating mechanism experience.

A vital regard for mechanism users is a support for hardware. If we have used Linux in a past, it competence have had difficulty detecting your printer or a third-party device.

Today, however, many of a inclination work good but installing any drivers, as Linux now supports 3,000 printers, 1,000 digital cameras and 200 web cams. In fact, we can even sync your iPod/iPhone song with a Rhythmbox media actor but installing iTunes.

Take a jump

If we are now prepared to try Linux on your computer, we don’t need to uninstall your existent handling system. You can simply dual-boot Linux with Windows or Mac. What’s more, Linux also has a ability to run as a full OS directly off a CD or a coop drive, vouchsafing we try it out before installing it. Be warned, though, a speeds would be a small slower than what we get if we were to implement it on your tough disk.

The best part, of course, is that Linux is free. And this cost is customarily upheld on to a consumer, as PCs regulating Linux from Dell and Wipro cost about Rs. 3,000 obtuse than a same indication bundled with Windows. Considering a benefits, it competence be inestimable to give Linux a chance…
