The OGSA Data Architecture

One of my many hats is as co-chair of the OGSA Data working group of the Open Grid Forum. We work on the data-oriented aspects of the Open Grid Services Architecture (see also here), covering the description, movement, access, replication, federation and storage of data in a Grid environment. Our aim is to provide a framework that links existing standards with those in development, and to show gaps that are not currently covered by standards work.

We had a fruitful face-to-face meeting here in Edinburgh last week, in which we concentrated on the descriptions of the interfaces in the architecture. The architecture is really a toolbox of data services that can be composed in various ways to address a range of use cases. As I expected, this focus helped us to to describe in greater detail how the various components will work together.

I believe we should have a draft of the architecture ready for public comment soon. I'm looking forward to actually completing this work. It's been a slow process, as we have had to bring various distributed groups on board throughout, but that's the only way to create a standard that will actually have any effect in the real world.

Webinar: Powering your business with Cloud Computing

On October 14th, I will be hosting a Grid Computing Now! web seminar on the topic of Cloud Computing. We have lined up two very interesting speakers who are using Cloud now to make businesses work. Ross Cooney had a good technological solution to sell but couldn't make it economic until Cloud Computing allowed him to pay for his computation only when he needed it. He will discuss the instant benefits and long term impact of cloud computing to the development, competitiveness and scalability of your application. Alan Williamson created the BlueDragon Java CFML runtime engine that powers MySpace.com. He advises several businesses and will give an overview of the different types of services available and how to avoid being locked-in to a single supplier. You can register for this event here .

Business Model Canvas

A Business Model Canvas is a tool for mapping the core functions and capabilities of an organisation.  Compared to the Core Diagrams that I described in an earlier post , the business model canvas attempts to present more aspects of the business, starting with the value proposition – a statement of what the organisation offers to its users (in the business world, to its customers).  It shows the activities and resources, as Core Diagrams do, but also shows user relationships & channels, and also benefits and costs.  I’m not aware of any universities that have used this tool but you can find examples from elsewhere on the web. We are considering business model canvases as a tool for mapping the strategic capabilities of units at the University of Edinburgh.  Phil Taylor, our EA contractor, sketched an outline of what a business model canvas might begin to look like for HR: This is only intended to be suggestive: the real canvas would need to result from in-de...

"Just enough" Enterprise Architecture

I spent an informative and enjoyable day with a proto-community of people pursuing Enterprise Architecture in UK Higher Education.  Many of the participants had been previously involved in JISC projects and have enjoyed similar events in the past, so I began the day as a bit of an outsider.  In the University of Edinburgh, our progress in adopting "architectures" is mainly on the IT side, via our Applications Architecture and our use of Service-Oriented Architecture .  Enterprise Architecture would integrate all this IT activity with the business processes and goals of the University (or what I sometimes call the administrative processes, for those readers who are unhappy with calling a university a "business"). I've tended to be a little sceptical of fully-fledged enterprise architecture (EA) because it sounds like a mammoth undertaking and the organisations doing it have often been very large corporations.  The two main outcomes of the JISC experiences ar...
