I can start.
There are a few areas in which I would say that SSC has changed its strategy to try to make it easier for departments. First of all, we have pre-positioned some infrastructure before what we call “workload migration”, which is really about moving applications to modern data centres.
We did it on demand, and then it would take 18 months to build the infrastructure. We're working to pre-position infrastructure through our hosting services.
The second piece that is a challenge, I would say, is just how old some of these applications have become, so it becomes not just an upgrade but generational leaps of technology, so it's a very difficult skill set to build up.
Also, we need to look at how we build applications, in general, and how they get sustained funding.
I ran a number of applications in previous roles when I was with the cyber centre. We made sure we invested continually in upgrading those applications to keep them fresh.
Perhaps I'll turn it over to Catherine, from OCIO.
