We can tell everything because it's a public offering, everyone knows about it. We use a large variety of VM sizes and families, but the major common factor between all of them is AWS Nitro, which is a key lightweight VM technology that AWS introduced with the next generation or new generation. When it comes to the game servers, the game servers run in C5. If we have some backers watching the livestream from the days before 3.0, we were doing some comparisons between the C4 and the C5. These were changes in the hypervisor, changes in the CPU powering the VM underneath. When it comes to the cloud, you're usually trying to hit a very specific sweet spot for your workload. So for the game servers, we have to meet in two areas. We need to maintain a decent ratio between the memory and the compute. And we need to make sure that we have very fast compute to see if I have fed that very well. We have other services that are single threaded that we need a very, very fast single core. We have other services that require moderate CPU clock speed, but they have larger memory usage. They will be running in R5. So it's all in our availability. A lot of our workload, we try not to be stuck to one single size, because we need to make sure if there is any issues and we cannot allocate VMs from that size, we always have a backup size. We have backup regions behind our regions, but sometimes you have to choose your battle, whether you're willing to go to a second region to allocate resources or you're willing to go for the second most optimal machine size. I hope this is not so boring, but we use a lot of them and we try to use the new ones.

The thing that's interesting about that is that you realize that sometimes you try to get a VM from the cloud and you can't, because they're out of VMs.
