As per requirements: - You have a public-facing application named App1. App1 is comprised of the following three tiers: A SQL database, A web front end and A processing middle tier. Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only. - Move all the virtual machines for App1 to Azure. - Minimize the number of open ports between the App1 tiers. Box 1: 1 1 VNET and then follow the N-tier application architecture. Box 2: 3 3 Subnets (1 Subnet for each tier of the App1). The tiers can communicate each other, because they are inside the same VNET. Of course you would need additional NSGs to restrict traffic.
