In 2018, we started using BlueDolphin for a cloud migration. That was a huge operation, involving more than 150 applications and 200 servers. We wanted to phase out Citrix. That could have posed some serious risks. What’s more, we didn’t know exactly how our application and server landscape looked. SLTN advised us to use BlueDolphin for the process. They had already used it for their cloud migration.
With 1,000 employees, you simply have to work with architecture
We successfully completed our migration in 2018. The information and overviews we produced were extremely useful, so we decided to continue with BlueDolphin for the rest of our architecture. I didn’t have that knowledge at the time, so we hired it through ValueBlue. But I was so enthusiastic that I started to take all kinds of courses: ArchiMate, BPMN, TOGAF and NAF’s six-month Enterprise Architecture Master Class. Then I applied that knowledge directly to our organization, such as the application functions. That’s how we found out, for example, that we had 10 ‘scan/recognize’ applications. We originally thought we had 3. But it turned out that we had an extra 7. So we could make some savings there. It feels great to discover these kinds of things.
We had another problem: the interviews with our stakeholders for the cloud migration showed that nobody besides our CEO and the ICT Manager was really familiar with architecture. Our CEO fully supported the choice, because he believed that you simply have to work with architecture when you have 1,000 employees or more. A staff of 1,000 is a tipping point after which it’s impossible to keep track of everything without tools and resources such as architecture. To implement the system properly, we had to involve all our stakeholders. We spent the first six months listening to people: What do you need?, Who can we help with insights?, Who can we help with choices?, and so on. Purely to give the stakeholders an idea of what architecture is all about.
