Cloud and the Future of Business: From Costs to Innovation

March 21, 2011

I have not been updating this blog for a while as I have been busy writing commercial papers on Cloud Computing. The first of these, for Accenture, has just been published and is available here

The report outlines our” Cloud Desires Framework” in which we aim to explain the technological direction of Cloud in terms of four dimensions of the offerings – Equivalence, Abstraction, Automation and Tailoring.

Equivalence: The desire to provide services which are at least equivalent in quality to that experienced by a locally running service on a PCor server.

Abstraction: The desire to hide unnecessary complexity of the lower levels of the application stack.

Automation: The desire to automatically manage the running of a service.

Tailoring: The desire to tailor the provided service for specific enterprise needs.

(c) Willcocks,Venters,Whitley 2011.

By considering these dimensions to the different types of cloud service (SaaS, PaaS, IaaS and Hosted service (often ignored – but crucially Cloud-like)) it is possible to distinguish the different benefits of each away from the “value-add” differences. Crucially the framework allows simple comparison between services offered by different companies by focusing on the important desires and not the unimportant technical differences.

Take a look at the report – and let me know what you think!

Simon Wardley, “Cloud Computing – Why IT Matters”

October 28, 2010

Simon Wardley of Canonical provides a lively discussion of the definition of Cloud Computing. Having criticised the profusion of Cloud definitions he then produces his own – and one which I particularly like:

“Cloud Computing is a generic term used to describe the disruptive transformation in IT towards a service based economy driven by a set of economic, cultural and technological transformations”

See the video of his talk on YouTube: YouTube – OSCON 09: Simon Wardley, “Cloud Computing – Why IT Matters”.
