Security? Cost? Go With Thin Clients

In large organizations paranoid about security and having huge IT bills, thin clients are the way to go.“it quickly became clear that the DoD network, with more than 15,000 different sub-networks, was simply too large and had too many distributed resources to be defended effectively.
The NSA faced similar problems, he added, noting that during much of his time leading the NSA he had three or four separate computers in his office, each of which was needed to access a separate network.
The NSA completed its transition to a cloud/thin client model near the end of his time with the agency, and Alexander said it not only improved security, but also resulted in a savings of 500 million dollars in addition to improved service.”

The users in the US government also report improved service! Many folks still believe you need a big powerful box close at hand to have performance. That may be true for some purposes, but all kinds of people working on huge data or single-page documents get great performance using thin clients. They get the performance of the server (could be a cluster) which can exceed the power of any PC by many orders of magnitude. The “network lag” folks yap about is of the order of milliseconds, on a LAN. Do you care about that when the job that might take minutes on a PC happens in the blink of an eye? Even on my simple setups in schools and labs, users were amazed to see their biggest applications pop open a window on their screen in less than 2s (lots of stuff cached in RAM on the server) when on the same hardware used as a thick client that took 10-15s (lots of stuff sought all over a single slow hard drive). One guy even fell off his chair. I’ve warned people ever since to be prepared for better performance.

Bean-counters love thin clients (like this one). Every business has them… In UK, “83% of wealth management organisations currently use some form of thin or zero client desktops, with more than half (58%) saying speed of deployment is the biggest benefit. This came ahead of flexibility (48%), better cost structure (48%) and ease of use and management (48%), which are all cited as key benefits.” A lot of those still use M$’s OS as the back end but that’s much easier to change once M$’s OS is off the client PCs. Those same folks likely don’t use M$’s OS on their smartphone or tablet. The job of installing GNU/Linux on a few servers is reduced by orders of magnitude over installing it on many PCs. The number of seats for which M$ collects a bill become conspicuous when management can tell exactly what every seat is doing…

Nope. Wintel is in trouble. Bill Gates’ dream of a licence on every hard drive on every desktop is on its last legs. M$ now has to try to tax the server to death and GNU/Linux reigns there. GNU/Linux has a much larger share of thin clients than of legacy PCs.

Linux in Education, technology

Finnish Schools Save Big With FLOSS

“Municipalities in Finland that have switched their schools to Linux and other open source solutions are saving millions of euro. Typically, our centrally managed open source computers are at least 40 percent cheaper than the proprietary alternative. The total savings could be 10 million.” This is what I have been writing about all these years. Using FLOSS and GNU/Linux in schools saves a bundle. There are the licensing costs straight up and then there is the flexibility of the GPL versus the restrictions of the EULA. Configuration and operation are trivial by comparison with FLOSS, because you can do whatever you want immediately. I’ve seen it repeatedly. New systems cost half as much and migrating old systems costs a fraction of that. The saving in money is important but so is the saving in time. In a typical school the effort could drop from many hours per week to minutes.

Lenovo And IBM Go Another Round

In a manner similar to the sale of the PC business, IBM has agreed to sell the x86 server business to Lenovo. One detail that I think is important is that “Approximately 7,500 IBM employees around the world, including those based at major locations such as Raleigh, Shanghai, Shenzhen and Taipei, are expected to be offered employment by Lenovo.”

I think this means a considerable increase in Lenovo’s GNU/Linux talent pool… Will any of that leak into the client division? With thin clients perhaps it does not need to. The talent’s mostly on the server anyway. This could erode Wintel in business eventually. It’s about time.

See IBM’s announcement.

The Writing On The Wall: Tablets And Smartphones Are The New PCs

Some of the trolls lurking here keep harping that small cheap computers just cannot replace the legacy PC because they lack something: keyboards, kilowatt PSUs or whatever. The fact is that that a large segment of users don’t require those “requirements”. Their purposes are multimedia and Internet, something small cheap computers have been able to do for years now.

“It’s not that you can’t use a laptop to do any of these things. I’ve used a laptop as a tethered shooting companion for photography for years now. Seeing instant feedback as I shoot speeds up the process and makes editing faster, it’s great. But I’ve never wanted to use a laptop. They’re bulky, they’re not the right form factor and they’re not optimized for easy one-handed operation (not counting the one you hold them with, thank you). And some of these cases, like diving, present an impossible challenge for laptops. They’re simply not the right tool for a lot of jobs.”

Then there’s mobility… something everybody but the bed-ridden have and many people want in their IT. You just can’t lug around kilowatt PSUs or even hair-driers as easily as a small cheap computer. If you don’t need a keyboard, why drag one around, especially those flat keyboards found on notebooks? I hate those. Give me my zombie keyboard from Fujitsu anytime. It fits my hands and I can plug it into a small cheap computer if I want to type… A big box AND a keyboard are not what I require. I just need a keyboard. I also want a big display, something I can’t have with a notebook so small cheap computers work for me. For storage I can use a server. For heavy computing, I can use a server too. I don’t need either of those in my client PC. I use a truly networked OS, GNU/Linux.

The writing is on the wall. The slowdown in sales of ATX boxes and notebooks is real. It’s not a fad. Small cheap computers are taking over a huge share of IT whether M$ and fans are ready or not. The world is not going to wait for Wintel to get its act together. While the current share of tablets and smartphones is significant, imagine a world in a few years with this kind of sustained growth.

See The Tablet Is The New General Purpose Computer.

IDC: “For the full year 2013, unit shipments declined -10.0% from 2012, a record drop reflecting the changes in mobility and personal computing affecting the market. While commercial purchases helped to prevent a larger decline, the consumer side remained weak.”

IDC: “worldwide tablet shipments are expected to reach 221.3 million units in 2013, down slightly from a previous forecast of 227.4 million but still 53.5% above 2012 levels. Shipment growth is forecast to slow to 22.2% year over year in 2014 to a total of 270.5 million units. By 2017, annual market growth will slow to single-digit percentages and shipments will peak at 386.3 million units, down from the previous forecast of 407 million units.”

IDC: “worldwide smartphone shipments are expected to surpass 1.0 billion units in 2013, representing 39.3% growth over 2012. Despite a number of mature markets nearing smartphone saturation, the demand for low-cost computing in emerging markets continues to drive the smartphone market forward. By 2017, total smartphone shipments are expected to approach 1.7 billion units, resulting in a compound annual growth rate (CAGR) of 18.4% from 2013 to 2017.”

Retail Shelves

Unfortunately, I can’t drive around to a lot of retailers to examine their shelves so this survey of the web will have to do. I will restrict myself to Canadian sites. The rest of the world varies, I know.

So, FLOSS is out there but the bastards still don’t make it very easy to find especially if you don’t know what you seek. What’s with that? Doesn’t it pay to advertise any longer?

Chrome OS, The New GNU/Linux Distro Accepted By OEMs, Retailers, Government and Consumers

Combine state of the art hardware from Intel and optimized software from Google and what do you have? A big bite taken out of the Wintel pie:
“Chrome OS represents a new form of computing," he said. "We are seeing great momentum there. External analysis estimates that they already represent over 25 per cent of the sub-$300 category. They’re big in education as well; they’re now deployed in over 5,000 schools in the US, which represents over 20 per cent of the school districts.”

see Intel reveals new Haswell-based Chrome OS kit from old, new partners.

This should put paid to the FUD coming from the Wintel camp, that M$ will save Wintel. It’s not happening. Just as Apple could not build a $500 tablet, Wintel cannot make decent small cheap PCs. Meanwhile the world turns and people love small cheap PCs because they are good enough for what people do. Because ChromeOS is essentially a thin client, much of the work of system maintenance is done remotely and users are not generally IT people. That works.

Here, let Google tell you why Chrome OS is wonderful for users.

Of course, Chrome OS is an on-ramp for the cloud and may well end up running lots of non-free software that works against the interests of users but it surely is smooth and will sell.

Everybody Loves Small Cheap Computers

“According to IHS iSuppli Compute Platforms Topical Report, lower-end computers classified in either the "mainstream" category or the "value" the mainstream desktop PCs is expected to account for 46.9% of the market each by the year-end, while the top-end PCs will account for only 6%.”

see Low end desktops and PCs dominate the market: report – Computer Business Review.

I have been writing much the same thing despite trolls spamming my blog with tales that high-end PCs are the way to go and that everyone should have one. It’s not true and here are the stats to prove it: only 6% choose high-end PCs. For everyone else ordinary PCs in almost any format are good enough. That’s what Moore’s Law does in the end, makes RAM and CPU inexpensive. You only need enough CPU and RAM to be expensive if you are crunching large data, which most of us do not. Hence the rise of the smart thingies, the ultimate small cheap computers that fit in your pocket of hand and do everything a desktop of a few years ago would do for ~$100, and it runs on a tiny battery… no more cables dangling… That’s price/performance, what people really care about. And the OS? */Linux of course. You don’t get any lower price/performance than $0/gHz-gB.

Extremadura Confirms Commitment to FLOSS

I have been writing for years about the benefits of FLOSS including GNU/Linux and thin clients in education. Government usage is not that much different so this combination should be useful in government as well. Apparently Extremadura thinks so:

“CIO Cayetano reaffirmed Extremadura’s support for open souce. Examples include the migration of the desktop PCs to a thin client infrastructure using Linux, and an overhaul of the region’s website, using an open source content management system.

In January, CIO Cayetano announced the start of a large-scale project to replace the current proprietary desktop software with an open source desktop. With 40,000 desktops, that would make it Europe’s second largest open source desktop example, between the French Gendarmerie (90,000 desktops) and the German city of Munich (14,000 desktops).”

see Spanish region of Extremadura confirms commitment to open source | Joinup.

Just do the maths. Asking the user’s PC to do less and the servers to do more is as natural as consolidation of servers only much more powerful in reducing costs. Thin clients suitable for desktop publishing, for instance, cost as little as $50 for the box whereas a notebook will cost at least $300. Considering you can have a better keyboard, monitor and mouse with the thin client for ~$150, there’s a savings of $100 per seat which can be used to buy an absolutely wonderful server or buy a totally adequate server for $30 or so and invest the rest in something you really need. Then there’s the operating costs. Less electricity, less fiddling, and no malware makes the IT just about free of cost in comparison.

Yes, Extremadura was ahead of the curve when they adopted GNU/Linux but they are a bit behind the times adopting the thin clients. Better late than never but then their GNU/Linux solution has probably reached the lifetime of its hardware. It’s time for change and still further reduced cost and complexity.

Acer Enters Thin Client Market

Thin clients are nothing new but Acer producing them is. Another interesting point is that some of these are ARMed so we could be seeing even more widespread adoption of */Linux on ARM and x86. DevonIT’s deTOS OS is one of the options. Acer is one of the top PC OEMs on Earth. They know people are loving small cheap computers.

“The new Acer Veriton N2110G Series comprise robust x86 thin clients that provide top-rate performance for power users. The Acer Veriton N2620G Series models are compact and flexible rich clients offering a TPM 1.2 compliant design and mainstream performance. The Acer Veriton N2010G Series are ultra compact ARM-based thin clients capable of delivering a rich multimedia experience at a significant value. All three series provide multi-tasking processing power, essential manageability and security tools as well as industrial compliance. Acer’s thin clients will be available through Acer resellers with prices starting at $239.”

If You Like Thin Clients Stay Away From That Other OS

Thin clients are wonderful. They are:

  • small
  • quiet
  • cool
  • inexpensive
  • fast

but M$ wants to take away one of their chief advantages. This is what BILL VEGHTE said in an interview at Credit Suisse Annual Technology Conference 2008:

“we’ve been very successful in making sure that if you want the full Windows experience on there, that that is not — that doesn’t hit our average selling price. It’s delivering that Windows experience just through a different model, but our ability to deliver that, to extract that value instead of sort of a royalty type thing, do it through Client Access Licenses, server side and client.”

I will stick with GNU/Linux, Bill. I want it all. Compared to those big, old boxes, they are beautiful, eh? Let us reclaim the desktop.thin_client1

Excitement About Thin Clients

IDC has issued a press release:”IDC Predicts Current Economic Crisis Still Provides For Pockets Of Opportunities Within The Asia/Pacific (Excluding Japan) Region in 2009

12 Dec 2008

9. Thin Clients Will Ride The Wave Of Cost Cutting And Desktop Virtualization

As the market matures, and better vendor collaboration results in software standards merging, virtualization to cut costs will extend beyond server virtualization in datacenters to virtualizing the desktop. In addition, deploying thin clients and a virtualized desktop environment will also reduce the carbon footprint. IDC is therefore optimistic and predicts that thin-client deployments on the back of desktop virtualization will gain traction in 2009, and further accelerate into 2010, as PC replacement cycles peak across the region. Full year 2009 thin-client shipments are expected to grow within the 12–15% range over 2008, to about 765,000 units.

10. The Economy And Mini-Notebooks Will Challenge The Way Computers Are Used And Sold In Asia/Pacific

IDC expects mini notebooks, a new product category created due to demand for devices that support mobility, to increase from around 5% of total notebooks shipped in the APEJ region in 2008 to more than 10% in 2009. The small cutesy form factor will be the primary selling point, but it will also change the way these devices are being used. With limited processing power and storage, users will be heavily dependent on being connected to the Internet, eventually running applications through the cloud. This demand for connectivity will further change the way mini notebooks are sold – instead of retail stores, partnerships with mobile operators are expected to proliferate with devices sold in service bundles like mobile phones, leveraging operators’ cellular 3G infrastructures. With vendors already looking at ways to overcome the challenges associated with this product category, IDC believes that mini notebooks will change the way traditional notebooks are used and sold.

This reflects the excitement I have been feeling about thin clients in education for several years. They are a great solution for cost-cutting and manageability. Of course, the IDC report is not only about education but the whole market in APEJ. Still, if businesses see the benefit, schools should as well.

The connection with netbooks is that both thin clients and netbooks share common features:

  • low cost
  • low footprint
  • low power
  • low noise

, all bringing value. The lack of horsepower for video is unimportant in many cases and, with the march of Moore’s Law, perhaps this will disappear as an impediment. That leaves the question, Why don’t more systems use thin clients?. I have no answer. Everyone to whom I have shown thin clients loves the improved performance and small footprint. Perhaps not enough people have seen them yet. I intend to change that in a small way at my next conference of teachers. I have a portable lab of thin clients under construction and will show it off with GNU/Linux, standard desktop applications, some particularly useful in education and some web applications like

Perhaps the IT industry is nervous about thin clients. After all, if thin clients cost less and last three times as long, isn’t there less money to be made selling them? Yes, but you should be able to sell many more and the servers to go with them. It is a paradigm shift, not the death of IT.
