Thoughts on British ICT, energy & environment, cloud computing and security from Memset's MD

The Next Revolution: Internet of Things

Over Christmas I have been pondering on the question of what the next big thing in technology will be, specifically in 2012. That question is perhaps especially poignant since we recently we lost one of our generation’s great innovators, Steve Jobs. When I recently took delivery of my magic mouse I was struck by how aptly it was named. If…

What Is Cloud Computing?

Here I provide a less technical description of cloud computing, which can be regarded as essentially the provision of computing resources and/or software as a utility, in the same way that your business uses familiar utilities, such as electricity, water, gas etc. Cloud computing enables you to pay for computing resources as you need them. These services are provided over the internet, on a consumption-based pay-as-you-use model, with short-term contracts and without up-front expenditure.


A couple of months ago HP started rumors that the G-Cloud had been canned, but that is most certainly not the case. I have spoken to a number of government officials and can confirm that it is going ahead. But what will it actually be, and is that what it should be? I was technical co-lead on phase two of…

Why Apple Should Make iCloud Open

The recent launch of Apple’s iCloud service has done much to bring mainstream attention and acceptance to the concept of cloud storage and syncing. But unless they adapt an open cloud standard they are facing an uphill struggle to attract business users. Here’s why.

Running a Business on Open Source Software

We’ve been running all our business systems over the ‘net for years (including instant messaging, email, document management, project management & collaboration) by using open source software. Both Nick & I are huge fans of open source, so I thought I’d share why and how we use it within Memset.

IaaS vs. PaaS vs. SaaS definition

One of the areas on which we reached clear agreement in the G-Cloud and App Store phase 2 was the definition the layers of the stack, infrastructure, platform and software, and their corresponding scalable, standardised counterparts: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Pleasingly, our delinations were very similar to prior work from two decades ago by IBM, except that ours incorporate virtualisation.

Definition of Cloud Computing, incorporating NIST and G-Cloud views

Following my involvement with the UK Cabinet Office’s G-Cloud and App Store programme I’m updating my definition of Cloud Computing, and also incorporating the NIST definition. My answer is “Cloud = Grid + (Utility * N)”, and here is how I arrived there…

Sanity-checking Twitter’s Valuation

Twitter has been valued at $1bn, but is that really sane? Time to get out my trusty calculator and offer a rather different assessment…

Intellect Regent panel with Paxman (video)

On 10th February I took part in a panel session at the 2009 Intellect Annual Regent Conference “Keeping ahead of changing markets”. The event took place at the Millennium Gloucester Hotel in London, was attended by top executives from the high-tech industry and was chaired by the BBC’s Jeremy Paxman, who I left speechless at one point!

The differences between IT outsourcing and Cloud Computing

I was recently asked by a journalist for my thoughts on the differences between traditional IT infrastructure outsourcing and “Cloud Computing”. When you get down to it, there are only really three differences between the two, but that does not stop Cloud being a significant threat to the old-guard of IT consultancies.
