Chromebooks' success punches Microsoft in the gut

Chromebooks' success punches Microsoft in the gut
Amazon, NPD Group trumpet sales of the bare-bones laptops in 2013 to consumers and businesses
Chromebooks had a very good year, according to retailer Amazon.com and industry analysts.

And that's bad news for Microsoft.

The pared-down laptops powered by Google's browser-based Chrome OS have surfaced this year as a threat to "Wintel," the Microsoft-Intel oligarchy that has dominated the personal-computer space for decades with Windows machines.

On Thursday, Amazon.com called out a pair of Chromebooks -- one from Samsung, the other from Acer -- as two of the three best-selling notebooks during the U.S. holiday season. The third: Asus' Transformer Book, a Windows 8.1 "2-in-1" device that transforms from a 10.1-in. tablet to a keyboard-equipped laptop.

As of late Thursday, the trio retained their lock on the top three places on Amazon's best-selling-laptop list in the order of Acer, Samsung and Asus. Another Acer Chromebook, one that sports 32GB of on-board storage space -- double the 16GB of Acer's lower-priced model -- held the No. 7 spot on the retailer's top 10.

Chromebooks' holiday success at Amazon was duplicated elsewhere during the year, according to the NPD Group, which tracked U.S. PC sales to commercial buyers such as businesses, schools, government and other organizations.

By NPD's tallies, Chromebooks accounted for 21% of all U.S. commercial notebook sales in 2013 through November, and 10% of all computers and tablets. Both shares were up massively from 2012; last year, Chromebooks accounted for an almost-invisible two-tenths of one percent of all computer and tablet sales.

Stephen Baker of NPD pointed out what others had said previously: Chromebooks have capitalized on Microsoft's stumble with Windows 8. "Tepid Windows PC sales allowed brands with a focus on alternative form factors or operating systems, like Apple and Samsung, to capture significant share of a market traditionally dominated by Windows devices," Baker said in a Monday statement.

Part of the attraction of Chromebooks is their low prices: The systems forgo high-resolution displays, rely on inexpensive graphics chipsets, include paltry amounts of RAM -- often just 2GB -- and get by with little local storage. And their operating system, Chrome OS, doesn't cost computer makers a dime.

The 11.6-in. Acer C720 Chromebook, first on Amazon's top-10 list Thursday, costs $199, while the Samsung Chromebook, at No. 2, runs $243. Amazon prices Acer's 720P Chromebook, No. 7 on the chart, at $300.

The prices were significantly lower than those for the Windows notebooks on the retailer's bestseller list. The average price of the seven Windows-powered laptops on Amazon's top 10 was $359, while the median was $349. Meanwhile, the average price of the three Chromebooks was $247 and the median was $243, representing savings of 31% and 29%, respectively.

In many ways, Chromebooks are the successors to "netbooks," the cheap, lightweight and underpowered Windows laptops that stormed into the market in 2007, peaked in 2009 as they captured about 20% of the portable PC market, then fell by the wayside in 2010 and 2011 as tablets assumed their roles and full-fledged notebooks closed in on netbook prices.

Chromebooks increasingly threaten Windows' place in the personal computer market, particularly the laptop side, whose sales dominate those of the even older desktop form factor. Stalwart Microsoft partners, including Lenovo, Hewlett-Packard and Dell, have all dipped toes into the Chromebook waters, for example.

"OEMs can't sit back and depend on Wintel anymore," said Baker in an interview earlier this month.

Microsoft has been concerned enough with Chromebooks' popularity to target the devices with attack ads in its ongoing "Scroogled" campaign, arguing that they are not legitimate laptops.

Those ads are really Microsoft's only possible response to Chromebooks, since the Redmond, Wash. company cannot do to them what it did to netbooks.

Although the first wave of netbooks were powered by Linux, Microsoft quickly shoved the open-source OS aside by extending the sales lifespan of Windows XP, then created deliberately-crippled and lower-priced "Starter" editions of Vista and Windows 7 to keep OEMs (original equipment manufacturers) on the Windows train.

But Microsoft has no browser-based OS to show Chromebook OEMs, and has no light-footprint operating system suitable for basement-priced laptops except for Windows RT, which is unsuitable for non-touch screens. And unlike Google, Microsoft can hardly afford to give away Windows.

But Microsoft's biggest problem isn't Chrome OS and the Chromebooks its ads have belittled: It's tablets. Neither Microsoft or its web of partners have found much success in that market.

Baker's data on commercial sales illustrated that better than a busload of analysts. While Windows notebooks accounted for 34% of all personal computers and tablets sold to commercial buyers in the first 11 months of 2013, that represented a 20% decline from 2012. During the same period, tablets' share climbed by one-fifth to 27%, with Apple's iPad accounting for the majority of the tablets.

"The market for personal computing devices in commercial markets continues to shift and change, said Baker. "It is no accident that we are seeing the fruits of this change in the commercial markets as business and institutional buyers exploit the flexibility inherent in the new range of choices now open to them."

But when you're at the top of the personal computing device heap -- as Microsoft was as recently as 2011 -- words like "change" and "choice" are not welcome. From the mountaintop, the only way is down.

Avaya builds massive Wi-Fi net for 2014 Winter Olympics

BYOD for 30,000 people creates extraordinary network demands

Ottawa, Canada -- Avaya engineers are putting the final touches on a network capable of handling up to 54Tbps of traffic when the Winter Olympics opens on Feb. 7 in the Russian city of Sochi.
wifi network

Sochi itself is a sprawling city of 350,000 people located on the Black Sea. Archeologists have found human remains in the area that date back tens of thousands of years. Today, Sochi’s subtropical climate makes it a popular Russian tourist spot.

The two locations where the Olympics will take place -- the Olympic village in Sochi and a tight cluster of Alpine venues in the nearby Krasnaya Polyana Mountains -- are completely new construction, so this project represents a greenfield environment for Avaya.

In addition to investing in a telecom infrastructure, Russia is spending billions of dollars to upgrade Sochi’s electric power grid, its transportation system and even its sewage treatment facilities. (Watch a slideshow version of the story.)

“The whole town is nothing but a constantly changing, $50 billion construction site; for instance we’ve seen the road outside our hotel be torn up at least four times. As for modern IT infrastructure? There was none to speak of. We have really had to start from scratch, right down to the laying of conduit before we could even begin installing fiber and cabling,’’ says Dean Frohwerk, Avaya’s chief network architect.

+ ALSO ON NETWORK WORLD Avaya's Wi-Fi set up in the last winter Olympics +

That’s quite a contrast from 2010, when Frohwerk and his team provided telecom and networking services for the games in Vancouver.

And this time around, the demands for bandwidth and connectivity dwarf anything that Avaya delivered in Vancouver, where the network was capable of handling only 4Tbps.

The Sochi network will serve 30,000 athletes, administrators and staff, media, IOC officials, and volunteers with data, voice, video, and full Internet access through the Games sites.

Adding to the challenge, “We expect these people to be carrying and using multiple wireless devices,” says Frohwerk. “In Vancouver, we only had to provision one device per user. This means that we really have to have the capability to support up to 120,000 users on the Sochi Wi-Fi network, without issues or interruptions.”

Plus, Avaya has to deliver 30 IPTV dedicated HD Olympic channels via its telecom backbone, and has to make these channels available to Olympic family users over the converged network. (IPTV support is an Olympic first on the network, eliminating the need for a separate CATV HFC network.)

Network upgrade

In Vancouver, Avaya installed the first all-IP converged voice, data and video network at Layer 2. “That network was laid out like a single mammoth installation, which worked well given that wired traffic outnumbered wireless four to one,” says Frohwerk.

“But we expect this equation to turn on its head at Sochi, with wireless being the four and wired traffic being the one. That’s why we have had to change our approach.”

Another lesson from Vancouver, he says, is that “requirements evolve and change during the Games, and that you have to be able to adapt the network configuration to accommodate these changes. We have also seen that ease of use is paramount: With so much going on, network operators must find it simple to make changes on the fly.”

In Sochi, Avaya’s Wi-Fi network will be split into five virtual SSID-based networks. There will be one network for the athletes, two for media (one free, one paid), one for Olympics staff, and one for dignitaries.

Each group will have its own access password, and extra layers of password protection will be added where needed. The Wi-Fi traffic will be distributed using about 2,000 802.11n access points across the Olympics Game sites; including inside the stands for the first time.

The network will be headquartered in a primary Technical Operations Center (TOC) in the coastal city of Adler, alongside the Primary Data Center. The secondary TOC and Data Center will be at the Sochi Olympic Park, located 10 miles northwest at the Games site.

Each TOC will be in a 50-foot by 70-foot control room. While one TOC is in use, the other will be kept in standby mode by a skeleton crew. Each TOC will be connected to the outside world by 10GB pipelines provided by Rostelecom, Russia’s national telecom operator.

“We have built the TOCs in separate locations to ensure redundancy in the case of a natural disaster or man-made incident,” says Frohwerk. “Should the Adler TOC go down, we would simply send the next shift to the Sochi TOC and carry on.”

The data and voice backbone is built on Avaya’s Fabric Connect, an open virtualization platform based on IEEE 802.1aq Shortest Path Bridging that enables a network fabric within/between data centers and the sites they serve.

At the core of the network are four Virtual Enterprise Network Architecture (VENA)-enabled Virtual Service Platform (VSP) 9000 switches, one in each TOC and one more in each of the mountain cluster points of presences.

Using Avaya ERS 8800 switches located at the network’s edge, the whole Sochi network will be virtualized at Layer 3 instead of Layer 2.

“Using a Layer 3 virtual software layer means that our switches can act intelligently locally, and do a better job of routing traffic,” Frohwerk says. “This reduces traffic jams, which means more uptime and better network speeds. It’s a step up from what we did in Vancouver, because the demands we’re facing are so much bigger here.”

Using Layer 3 will let Avaya’s network operators serve many more endpoints than they could in Vancouver. Each device logging in will get its own media access control address: Avaya will use pre-installed 802.1X certificates, the MAC address, or a captive portal to authenticate the device, while controlling the access level and bandwidth with the company’s Identity Engines software.

Avaya is also providing voice services and 6,500 voicemail boxes at Sochi using Avaya Aura Communication Manager (CM), Session Manager (SM), System Manager (SYMGR) and CM Messaging.

Challenges

Moving goods into Russia can be time-consuming in the best of situations. But moving massive amounts of equipment in time for the Games has been a real challenge for Avaya.

“This is why we have had people in Sochi for the past 18 months, to keep things coordinated and to make sure supplies get where they need to be,” says Frohwerk. “You can’t leave things to chance.”

Even with this level of supervision, it’s been a nerve-wracking experience for Avaya, like the time one of its equipment trucks lost radio contact for days while travelling through rural Kazakhstan.

Another truck arrived in Sochi with unprotected/uncushioned computer hardware after driving over hundreds of miles of bumpy, rough roads. “In both cases, the equipment finally arrived in usable shape,” he says. “But we had a few tense moments there for sure.”

Another challenge is training. In line with their agreement with Avaya’s Russian partners, the company is training 170 Russian technicians to provide Tier 1 and Tier 2 network support during the Games. A 30-person team from Avaya Global Support Services will provide Tier 3/4 support from Sochi’s TOC, supported by Avaya R&D staff around the world.

The training of these Russian technicians is under way and Avaya staff has rotated on site to “train” for the Olympics.

“We are doing our best to be well-prepared for whatever the Games throw at us,” Frohwerk says. Avaya’s outdoor systems are designed to handle extreme weather: “We’re not worried if it snows,” he says. “In fact, we hope it does, because these are the Winter Games, after all.”

At press time, Avaya had completed installing all of its equipment in Sochi. The company is now moving into test mode, pushing the network’s limits by putting it through multiple types of failure scenarios.

Apres ski

After the games end on Feb 23, much of Avaya’s infrastructure will be removed. But the telecom facilities it has built for the Games – including the telephone and IP networking for the Olympics skiing venue in the Caucasus, where a new resort town is being erected, will remain.

The company will also be helping to develop telecom facilities for the Grand Prix auto races that will held in Sochi later in 2014, and soccer matches there that will be part of the 2018 World Cup.

“We will be leaving behind quite a legacy telecom system when we leave Sochi,” says Frohwerk.

10 top tests of 2013

Network World tested hundreds of products in 2013, but here are our top 10 tests of the year. In order to make the list, the product review had to be a comparative test of multiple products in a single category and it had to break new ground or deliver fresh insight into an important product area.

Here’s the list:

1. WAN OPTIMIZATION – JOEL SNYDER
We invited every major network optimization vendor, and ended up with seven contenders: Blue Coat, Cisco, Citrix, Exinda, Ipanema, Riverbed and Silver Peak.

Our Clear Choice Test winner is Riverbed, which excels at the core WAN optimization functions of compression and de-duplication. If you’re looking for innovation, you’ll be as impressed, as we were, with Ipanema Technologies ip|engines and Exinda Networks x800-series.

For great performance, we were again impressed with Silver Peak. And if you’re running all Cisco at the network edge, Cisco’s WAAS is a no-brainer with big benefits at moderate cost.

2. MOBILE DEVICE MANAGEMENT – DAVID STROM
We looked at six products: AirWatch, Apperian EASE, BlackBerry Enterprise Server 10 (BES10), Divide, Fixmo, and Good Technology's Good for Enterprise. Each has a somewhat different perspective and different strengths in terms of what it can control best.

AirWatch had the widest phone/tablet/desktop support. But it also requires a collection of different downloaded apps that could be confusing to use. If you’re going the secure container route, Fixmo is a strong contender.

BlackBerry should be on your short list if your primary goal is protecting your messaging infrastructure. Good Technology is a mature product that features solid email security, fast device enrollment, extensive security policies and wide device support.

Divide had the most appealing management console and overall simplest setup routine. It features the best overall approach to MDM and is the easiest to operate, but has the most limited device OS version support. Apperian does a great job with setting up a protected app portal, but falls down on some basic MDM issues.

3. MIDRANGE MANAGEMENT TOOLS – BARRY NANCE
If your network has between 1,000 and 10,000 devices and computers, you have a midsized network. Your servers, connections and other resources suffer the same problems as larger networks, but your budget for keeping the network healthy is less than what large enterprises enjoy.

We tested six products that provide a management suite for mid-range networks: Paessler PRTG v12.4, Heroix Longitude v8.1, HP Intelligent Management Center (IMC) Standard and Enterprise v5.2, Ipswitch WhatsUp Gold (WUG) v16, SolarWinds Orion Network Performance Monitor (NPM) v10.4 and Server & Application Monitor (SAM) v5.2 and Argent Software Advanced Technology (AT) v3.1, including Argent Commander 2.0 and Argent Reports 2.0.
Argent Advanced Technology earns itself the Network World Clear Choice award, edging Heroix Longitude, which came in second. Advanced Technology gave us sophisticated thresholds, a responsive user interface, accurate device discovery, time-saving root cause analysis, helpful corrective actions and meaningful reports.

4. HOSTED VDI – TOM HENDERSON
We compared hosted virtual desktop infrastructure (VDI) products from Microsoft, Citrix, and VMware and came to many conclusions, but the most important one is this: Setting up hosted desktop sessions in a BYOD world is a complex undertaking.

Our Clear Choice Test winner is Citrix's VDI-in-a-Box for its ease of integration, flexibility of both hosted operating systems and variety of clients, and its end-user experience.

VMware's Horizon View 5.2 is also very capable and can scale dramatically, but it’s more limited in both hosts (Windows) and clients served. Windows 2012 Server is good, yet requires a buy-in to Microsoft's Windows System Center Configuration Manager, and has less client flexibility.

5. PERSONAL CLOUDS – WAYNE RASH
cloud computing

A personal cloud service lets you share photos, music and documents among all your devices easily and quickly.The good news is that these cloud services are normally free for a limited amount of data. Most vendors also offer premium or enterprise versions, which allow you to store more data and to share data, which is useful in a workgroup scenario, for example.

We looked at nine personal cloud services: Apple’s iCloud, Bitcasa, Box, Dropbox, Google Drive, Microsoft SkyDrive, MediaFire, SpiderOak and Ubuntu One. While iCloud, SkyDrive and Google Drive are optimized for their respective platforms, all of the cloud services work across multiple operating systems and different browser types.

There was no single cloud service that we considered a winner. All worked as advertised, all had their strengths, as well as peculiarities or annoyances.

6. LINUX-BASED SERVER OPERATING SYSTEMS – SUSAN PERSCHKE
The five products we tested -- SUSE Enterprise Server 11 Service Pack 2, Mandriva Business Server 1.0, ClearOS 6 Professional, Red Hat Enterprise Linux 6.4 and Ubuntu 12.04 LTS -- are all enterprise server versions offering commercial support options, either at the OS level or in the form of commercial management tools and support plans.

Our Clear Choice Test winner is Ubuntu, which delivered intuitive, uncluttered management tools, excellent hypervisor support, and transparency (commercial and open source versions are one and the same).

The remaining four contenders fell into two categories with Red Hat and SUSE representing enterprise-level offerings and Mandriva and ClearOS geared more towards small and midsize businesses. In the SMB segment ClearOS edged out Mandriva.

7. TWO-FACTOR AUTHENTICATION – DAVID STROM
Relying on a simple user ID and password combination is fraught with peril. One alternative is to use one of the single sign-on solutions we reviewed last year, but there are less expensive options that could also be easier to install.

That’s where two-factor authentication services come into play. Years ago, vendors came out with hardware-based two-factor authentication: combining a password with a token that generates a one-time code. But toting around tokens means that they can get taken, and in a large enterprise, hard tokens are a pain to manage, provision and track.

Enter the soft token, which could mean using a smartphone app, SMS text message, or telephony to provide the extra authentication step. We reviewed eight services that support up to five kinds of soft tokens: Celestix's HOTPin, Microsoft's PhoneFactor, RSA's Authentication Manager, SafeNet Authentication Service, SecureAuth's IdP, Symantec Validation and ID Protection Service (VIP), TextPower's TextKey, and Vasco's Identikey Authentication Server.

8. ULTRABOOKS – WAYNE RASH
We tested eight ultrabooks, all with touchscreens and all running Windows 8 Professional. They are: the astonishingly thin Acer Aspire S7 and Asus Zenbook UX31A, the flip-screen Dell XPS 12, HP’s Envy 400t-12, Lenovo’s business oriented ThinkPad Carbon X1 and the flexible Yoga 13, the Samsung ATIV Tab 7 that transforms into a tablet, and the Sony Vaio T-15.

Our favorite, because it was the easiest to type on and the easiest to use overall was the Lenovo ThinkPad Carbon X1. This ultrabook has three ways to control the pointer, had the best keyboard by far, yet it was still thin and light.

If you need your ultrabook to convert to a tablet, then you might like the Samsung ATIV Tab 7, or the Yoga or Dell, which fold or flip to become tablets. Acer and Asus win points for being sexy, thin and stylish, so if you want to impress in the conference room, these might be for you.

9. SOFTWARE-BASED NAS – ERIC GEIER
Earlier this year we tested Network Attached Storage (NAS) appliances. Now we're reviewing software-based NAS that you can load onto your own equipment — whether it's a PC, server, virtual machine, or in the cloud. We looked at FreeNAS, Openfiler, Open-E DSS, NexentaStor, and SoftNAS. All offer some sort of free solution or service, with some being fully open sourced.

Going with a software solution enables you to select and customize the hardware it runs on to best fit your particular application and environment. For a small and simple network you could load the software on a spare consumer-level PC, or for bigger networks purchase a server or run on a virtual machine.

On the other hand, going with an appliance may be better if you aren't comfortable selecting the hardware, installing the software, and then maintaining both. Appliances are generally more plug-and-play, whereas with software solutions you have to spend some time building your own appliance.

10. OPEN SOURCE MANAGEMENT TOOLS – SUSAN PERSCHKE
We reviewed four popular open source products - Nagios Core 3.5, NetXMS 1.2.7, OpenNMS 1.10.9 and Zenoss Core 4.2. All four products are mature, have extensive monitoring capabilities similar to their enterprise-grade counterparts, and are currently updated with good community support.

Zenoss is our top pick due primarily to its intuitive and professional-grade admin interface. Also we were able to configure our environment and run reports easily, and when help was needed, we found the user guide to be an excellent resource, a rare find in the open source world.

Nagios is a good choice if a smaller footprint is desired and the infrastructure is limited in number of devices. Although NetXMS has a somewhat cluttered user interface, it boasts a rich toolset that provides a lot of granularity for infrastructure management and gets a plus for attention to mobile. OpenNMS is another powerful net management tool capable of running on most platforms and with the ability to manage a lot of data.

What Contract IT Workers Miss About Being Full-Time

A survey of contract and freelance IT professionals shows healthcare and 401k plans are the most-missed perks of traditional employment, while there are many things they don't miss at all.

What would you miss most about "traditional," 9-to-5, office employment? According to a survey released today, the top three most-missed benefits and perks among independent IT pros are health insurance, brainstorming with colleagues, and 401K matching.

Surprisingly (or perhaps not), not many people missed the company holiday party or formal performance reviews, according to the survey, conducted by IT staffing and Workforce-as-a-Service firm OnForce, with 19 percent ranking formal performance reviews and 17 percent ranking the holiday party among the top two and three least missed aspects, respectively, according to the survey.

The Changing Face of IT

OnForce surveyed 1,337 anonymous, independent IT service professionals throughout the United States ranging in age from 21 to over 60, and found that 37 percent of respondents missed employee-provided health insurance, 30 percent listed brainstorming with colleagues as a benefit they missed, and 20 percent answered that they missed their former employers' 401k matching plans.

IT Careers
OnForce's CEO, Peter Cannone, says the results are in line with what he sees as the changing face of the current IT workforce, and that the results of the survey have broad implications outside the IT industry and beyond the pool of independent IT professionals.

"When you consider that 50 percent of today's workforce will join the ranks of the self-employed by the year 2020, and that 60 percent of IT service professionals willingly left full-time jobs to be their own boss, it's important for companies to understand the current needs of full-time and contract employees if they want to remain competitive," Cannone says, citing research obtained by OnForce.

The survey also revealed that different age groups are concerned with different benefits and perks. Of the 37 percent of respondents that ranked health insurance as the most missed benefit, most fell into the 40-49 year age bracket, while 10 percent are aged 50-59, 9 percent are aged 30-39, 3 percent are aged 21-29 and over 60 years of age.

While health insurance and 401K plans are still a top priority among the workforce, the survey also showed that social and professional development in the workplace are extremely important, especially to those that fall between ages 40 and 49. Yet, according to the survey, that same demographic rated the company holiday party and formal performance reviews one of the least-missed aspects of 'traditional' work life.

But there's one aspect of traditional, full-time employment that remains almost universally reviled, regardless of demographic: commuting; 38 percent of all respondents, regardless of age group, cited this as their least-missed aspect of 'traditional' employment. You can see more about the survey here.
