The first step to consider in this scenario is that the application code needs to run on traditional VMs. Presently, there are only two VMs that are overloaded at busy periods but underutilized at quiet periods. VM scale sets would be an ideal choice because the application can be built using an image and then configured to scale in and out, adding and removing nodes in response to demand.

Next, to provide the best performance in each country, the application could be duplicated in different Azure regions, for example, East US, East Asia, and West Europe.

As the development team has already confirmed, they could migrate the application to Cosmos DB; this would be a great move as Cosmos DB can be globally distributed with multi-region writes. Therefore, replicas of the database could be created in each of the Azure regions with read/write capabilities. This would ensure there is as little latency as possible for customers in each region.
