UCAS - The Cloud Journey

The first session this morning was from James Munson and Andy Gillett from UCAS. James described UCAS’s migration from a locally-hosted service in 2012 to a cloud-based service in 2014.  On results day, UCAS gets 235 logins/second.  They had unhappy experiences in 2011 & 2012 and so needed to change.  UCAS needed scalability, security and control of costs, so they chose a public cloud supplier rather than a private cloud.  Their "Track" application was written in .Net so was a natural fit for Microsoft Azure.  Amazon provided the best service for databases.  UCAS already used Rackspace for their web presence, so they went with a mixed set of suppliers.  If they had had more time, they might have preferred a single supplier.

Their architecture handles DDOS suppression, load balancing, monitoring et al. It is built for horizontal scalability with stateless applications etc.  They use Puppet for automatically managing environments.  The UCAS technology team now has sub-teams for customer engagement, IT strategy and architecture, solution delivery, and service assurance.


Andy Gillett described the UCAS's IT engagement strategy.  He outlined the need to apply ITIL service management to UCAS services.  They have established a technical forum, 1:1 meetings, use of social media, user groups, relationships with student system vendors, and relationships with UCISA, HESA and ITSMF.

James noted that putting software into the cloud isn’t a panacea.  You may still have old wine in new bottles – code that needs to be refactored or replaced.  But the gains in flexibility and cost control is worthwhile.

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…

New staff for the EA team

I'm delighted to welcome Jason Murphy, who joins us as our CRM Architect, and Wilbert Kraan, our new Data Architect.  Both Jason and Wilbert have worked as consultants for several years and bring new skills and considerable experience to IS.  They both know more than I do about their respective fields, which is how I like to hire people.

So the Enterprise Architecture practice now comprises the three of us, instead of me working on my won, which means we have more capacty to guide the University's IT architecture.  We can offer a greater range of skills and can bring a wider range of experience to bear.  I'm really excited about the opportunities this presents.

As his job title implies, Jason will focus on contact relationship management, working to build a user community and to create a strategy for managing and improving the University's relationships with prospective students, research partners, community organisations, and other parties - to give them all a better …
