Ian Foster finds an interesting take on Green IT

Ian Foster notes a project at University of Notre Dame near Chicago which is distributing research computing facilities in order to provide heat to campus buildings. This is an interesting trade-off: on the one hand, the distribution of resources means that the waste heat is put to good use; on the other hand, it's possible that each distributed installation is less efficient that a good-quality centralised machine hall.

This is another example of where we need good quality models and well-measured example deployments to help us decide which approaches give the best results.

2016 has been a good year

So much has happened over the last year with our Enterprise Architecture practice that it's hard to write a succinct summary.  For my day-to-day experience as enterprise architect, the biggest change is that I now have a team to work with.  This time last year, I was in the middle of a 12-month secondment to create the EA practice, working mainly on my own.  Now my post has been made permanent and I have recruited two members of staff to help meet the University's architectural needs.

I have spent a lot of the year meeting people, listening to their concerns and explaining how architecture can help them.  This communication remains vital, the absolute core of what we do and we will continue to meet people in this way.  We also talk to people in other Universities in order to learn from what they are doing and to share our own experience back.  A highlight in this regard was my trip to the USA last January.

Our biggest deliverable for the past year was the design of the data wa…

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…

A brief summary of our major initiatives

I notice that in 2016 I wrote 34 posts on this blog.  This is only my fifth post in 2017 and we're already three-quarters of the way through the year.  Either I've suddenly got lazier, or else I've had less time to spend writing here.  As I'm not inclined to think of myself as especially lazy, I'm plumping for the latter explanation.

There really is a lot going on.  The University has several major initiatives under way, many of which need input from the Enterprise Architecture section.

The Service Excellence programme is overhauling (the buzzword is "transforming") our administrative processes for HR, Finance, and Student Administration.  Linked to this is a programme to procure an integrated ERP system to replace the adminstrative IT systems. 

Enabling Digital Transformation is a programme to put the middleware and architecture in place so that we can make our processes "digital first".  We're implementing an API framework, a notification…
