Cloud why now?

I wrote and published a paper, called Cloud why now? on the Knowledge Transfer Network site. How new is Cloud Computing? It is a clear evolution if two trends in IT architecture that have had an immense and limited success. The successful trend is distributed computing and the less successful one utility computing. What is driving this evolution and why now? This article has a quick look at the trends that have brought this to this point and looks at the fact that like most economic revolutions, it’s a confluence of both socio/economics and science. The article concludes by looking at the paradox of data, to see how it is both a driver of change, and an inhibitor. …

Billing for Clouds

When considering the some of the issues related to building private clouds, the “Usage to Billing” problem was raised and I was reminded of Emlyn Pagden’s Blueprint, “The Utility Model PII” 2003. I had been consulting with a mid sized European Investment Bank, and discussed the architectural problem with them, and Emlyn. Its a while since I have read Emlyn’s paper, but he took the architectural decomposition,  …

Throughput Computing

Sun finally launched it’s chip multi-threading systems, promising a revolution in throughput and cheaper MIPS/Watt. This was done at a synchronous event in New York & London with a webcast for those who couldn’t make it in person.  Jonathan Schwarz travelled to London to speak to his European customers, as did  I. I recorded this on my sun oracle blog in several articles. In February 2016, I undertook an exercise to copy as many as made sense, of my original blog articles across from the oracle site to my/this wordpress blog. This article represents the highlights of the original record of my day.  As with the other articles copied, you still read the originals at the oracle site, here…, although all the pointers to Sun resources, including the presentations are now broken, and hence removed with the exception of  Andy Ingram’s, Workload based Systems Design 2005 which I have rescued and reposted because it was important then and remains so today. …

Sun’s new utility

Robert Youngjohns, spoke arguing that Applications will conform to the Utility platform (Solaris or J2EE), Is this true? Robert uses his own personal solution to his electricity problem after moving to the US where he had to get rid of his lovely solid UK plugs for the nasty dangerous easy to fallout US plugs, with one exception. Robert reckons there’ll be exceptions in IT as well, although his domestic example is a legacy appliance. My concern is the new applications that deliver compelling competitive advantage and are written in house.  …
