That's the work we're undertaking right now, and it's not a one-to-one answer, because there is a cost and a benefit to speed, and there's a cost with buying computing from Amazon Web Services or Microsoft Azure versus having all of the infrastructure that Sony needs to put in place to physically operate a facility with servers and all the things that we need to host on premise.
So we really needed to do what we've done, to move some of our systems over to the cloud in order to have some real-life examples around the cost and the benefit of a cloud environment versus the cost and the benefit of an enterprise data centre, but I would say that the theory that it is less expensive to go to the cloud is not a good theory. It is also not a good theory to say that you can get the equivalent amount of agility from a data centre environment that you can get from a cloud environment. We've seen that throughout COVID and how we've been able to use cloud to move very quickly on some things.
We need to balance all of those things to come up with the right economics because it takes staffing to do things in both environments and that has costs associated with it as well.
