Entering the Era of the Cloud

The Grid Computing Now! webinar on Cloud computing is now available on the GCN web site. We had to make some last-minute changes because Alan Williamson was unable to join us; so after Ross Cooney finished his presentation, he and I had an extended discussion, including several questions sent in be the audience. It went very well; a couple of times I wondered whether I should bring the broadcast to an early close, only to receive new questions from the audience that kept the debate going.

We covered many issues, but perhaps the key issue was when to use cloud and when to keep provision in-house. This depends on measurement and requirements (doesn't everything?). In the case of EMailCloud, Ross estimates that if a server will be kept well utilised for more than 8 hours a day, it is cheaper to run that machine in-house, while using the cloud for peak loads, disaster recovery, and so forth. We went into more detail than that - if you're interested, watch the webinar!

We also covered the issue of interoperability. This is vital for users, because cloud services do fail. Ross develops his applications for two vendors, which is an overhead for him. The industry needs some common interfaces. In my opinion, these will only come about if users and smaller vendors push for them. The big vendors will each be hoping to be the next Google and will see commonality as a threat.

Take a look!

Changing Principles

In EA, architecture principles set a framework for making architectural decisions.  They help to establish a common understanding across different groups of stakeholders, and provide guidance for portfolios and projects.  Michael Durso of the LSE gave a good introduction to the idea in a webinar last week for the UCISA EA community.

Many organisations take the TOGAF architecture principles as a starting point.  These are based on the four architectural domains of TOGAF: business, information/data, applications, technology/infrastructure.  These principles tend to describe what should be done, e.g. re-use applications, buy in software rather than build it, keep data secure.  See for example the principles adopted at Plymouth University and the University of Birmingham.

Recently though, I encountered a different way of looking at principles.  The user experience design community tend to focus more on how we should do things.  E.g. we should start with user needs, use iterative developm…

Why the UCISA Capability Model is useful

What do Universities do?

This may seem a strange question to ask and the answer may seem obvious.  Universities educate students and undertake research.  And perhaps they work with industrial partners and create spin-off companies of their worn.  And they may work with local communities, and affiliation bodies for certain degress, and they definitely report on their activities to government bodies such as HEFCE.  They provide student services and support.  The longeryou think about it, the more things you can think of that a University does.

In business, the things that an organisation does are called "capabilities", which is a slightly strange term.  I think it is linked to the HR idea of a combination of the CAPacity and ABILITY to do a task.  Whatever the name, it is a useful concept.  A capability is more basic than a process: a University may change the way it educates students but as long as it remains a University it will educate them one way or another.

A new EA Repository

One of my goals since starting this job two years ago has always been to create a repository for architecture documents.  The idea is to have a central store where people can find information about the University's applications, data sources, business processes, and other architectural information.  This store will make it easier for us to explain our plans, to show the current state of the University's information systems, and to explain what Enterprise Architecture is all about.

It's taken a long time to reach this goal, mainly because we're often had more pressing and immediate work to be done.  The creation of a repository is one of those tasks that is very important but never quite urgent.  So I'm now very happy to say that we are in the process of deploying a repository and modelling tool.


This is the culmination of a careful process to select the most appropriate tool for our needs.  We began by organising several workshops to gather requirements from a rang…
