I'll take that one and then Rajiv can add something if he wants to.
The reason we're shifting from cloud-first to cloud-smart, first of all, is that using the cloud allows us to stand things up very quickly. Where we would take potentially months to stand up an environment in which we can start building a new system for Canadians or migrating a new system for Canadians, we can do that in hours or days in cloud, so there's a huge opportunity to move more quickly to deliver service to Canadians.
We needed to get the government going in a direction because we were all data centres, and in fact SSC had an issue around the fact that they had some very old data centres. Before we just picked up and moved to a data centre, we said let's start moving some of the stuff into the cloud. As part of that, many of the things we've learned were pointed out in the Auditor General's report, including the fact that we need more maturity around our cost model. That is why we went into more of a cloud-smart model, so that we are really going to put that financial lens on migration to consider whether it's more efficient, when you put all things together, such as speed and cost, to have it in the cloud or to have it in an enterprise data centre.
So that was really the shift, and we'll continue to tune that as we go forward. As I noted in my remarks, there will never be a world in which we will be fully in the cloud, and that situation is consistent with those of many large organizations across the globe.
