Myths & Legends of the 20th Century

I found my neatly ironed, black ‘Citrix’ monogrammed shirt hanging in my wardrobe today. It’s a long time since I last wore it and it made me stop and wonder how the arrival of Windows Server 2003 has impacted what was once a highly lucrative ‘thin-client’ computing niche, dominated by of course Citrix.

Once upon a time the world was hell-bent on a course towards thin-client computing and industry figures were writing the obituary of the Personal Computer, which was to be replaced by Network Computers, NCs or ‘Thin-clients’ or even Java-powered devices, courtesy of Lotus Development and it’s eSuite. Nothing quite happens to plan in this business but Microsoft, careful to hedge its bets, with Windows NT, developed a strategic relationship with Citrix, the darling of the Thin-client revolution.

Citrix created a completely new way of looking at Windows systems based on Ed Iacobucci, its founder’s, mainframe experience. Thin client meant better management, lower operating cost, more mobility and best of all, a break between the hardware and the software upgrade cycles. Unfortunately, in practice, the technology didn’t quite deliver the economic benefits that were promised. Why not? Well, once it is developed, software does not cost anything to manufacture so it is difficult to price. Vendors therefore tend to set prices based on “value to the customer”. In other words, they maximise the return on each client. In the case of thin client, Citrix charged a licence fee for every client, which made thin-client computing rather more expensive than it should have been..

All right, it was all rather more complicated than this but the results had Microsoft steadily building more Thin-client technology into Windows, while Citrix increasingly specialised in the added-value department, as Microsoft nibbled-away at its functionality in every new Windows Server release. Today, if you are running a mixed environment with non-windows clients and UNIX servers, Citrix still has a place in your IT strategy. Otherwise, its role is less clear. Mark Tennant, Microsoft’s Windows Server 2003 product manager remarks a little more diplomatically, “Windows gives users the basic terminal services in Windows 2003 but Citrix strengthens the proposition by offering additional value, which includes single sign on and mixed client support".

Functionally, things have however changed between Windows NT, Windows 2000 and Windows 2003 in a way, which could save customers an average of £100 per client according to James Barden of thin-client specialist Insite (Europe).

According to Barden, “Even using Windows 2000 Server, delivering thin client services to users without costly Citrix client licences meant compromises in usability, screen quality and manageability. Microsoft’s Windows 2003 sees the majority of Citrix functionality now included in the standard product. For Citrix, this represents a commercial problem, but for businesses striving to strip cost out of projects, it represents a huge cost advantage”.

So there you have it, upgrading to a new version of Windows may actually reduce overall computing costs, with a 60% reduction in the risk of security compromise as a bonus. If Barden has his sums right, then Windows 2003, deployed in areas, such as the public sector, where Thin-client computing is popular, could spell the end of one of the great myths of our time, up there with weapons of mass destruction and the return of Elvis. Driving down the total cost of ownership with Windows might be true after all?

Mainframe to Mobile

Not one of us has a clue what the world will look like in five years’ time, yet we are all preparing for that future – As  computing power has become embedded in everything from our cars and our telephones to our financial markets, technological complexity has eclipsed our ability to comprehend it’s bigger picture impact on the shape of tomorrow.

Our intuition has been formed by a set of experiences and ideas about how things worked during a time when changes were incremental and somewhat predictable. In March 1953. there were only 53 kilobytes of high-speed RAM on the entire planet.

Today, more than 80 per cent of the value of FTSE 500* firms is ‘now dark matter’: the intangible secret recipe of success; the physical stuff companies own and their wages bill accounts for less than 20 per cent: a reversal of the pattern that once prevailed in the 1970s. Very soon, Everything at scale in this world will be managed by algorithms and data and there’s a need for effective platforms for ma…

Civilisational Data Mining

It’s a new expression I haven’t heard before. ‘Civilisational data mining.’

Let me start by putting it in some context. Every character, you or I have typed into the Google search engine or Facebook over the last decade, means something, to someone or perhaps ‘something,’ if it’s an algorithm.

In May 2014, journalists revealed that the United States National Security Agency, the NSA, was recording and archiving every single cell-phone conversation that took place in the Bahamas. In the process they managed to transform a significant proportion of a society’s day to day interactions into unstructured data; valuable information which can of course be analysed, correlated and transformed for whatever purpose the intelligence agency deems fit.

And today, I read that a GOP-hired data company in the United States has ‘leaked’ personal information, preferences and voting intentions on… wait for it… 198 million US citizens.

Within another decade or so, the cost of sequencing the human genome …

The Big Steal

I’m not here to predict the future;” quipped the novelist, Ray Bradbury. “I’m here to prevent it.” And the future looks much like one where giant corporations who hold the most data, the fastest servers, and the greatest processing power will drive all economic growth into the second half of the century.

We live in an unprecedented time. This in the sense that nobody knows what the world will look like in twenty years; one where making confident forecasts in the face of new technologies becomes a real challenge. Before this decade is over, business leaders will face regular and complex decisions about protecting their critical information and systems as more of the existing solutions they have relied upon are exposed as inadequate.

The few real certainties we have available surround the uninterrupted march of Moore’s Law - the notion that the number of transistors in the top-of-the-line processors doubles approximately every two years - and the unpredictability of human nature. Exper…
