VPC network foundations
Explain the practical point behind "The VPC is the floor every Cursor service stands on."
Step 1 of 3
The VPC is the floor every Cursor service stands on. Get the address plan and the subnet topology wrong on day one and you pay for it in every migration, every peering and every region you add later.
A Software Engineer, Infrastructure at Cursor owns these network foundations for a product serving over 1M daily active users. The design-round bar is not reciting AWS terms. It is showing you can lay out a VPC that survives growth across regions and accounts without an IP renumbering project and that you know exactly where traffic is allowed to flow and where it is blocked.
