Do we have to spin up new infrastructure for each customer or can we deploy into what they already have?

ANSWER

The common pattern is a new VPC and new cluster per customer — the vendor owns the compute layer.

Trying to deploy into a customer's existing environment means inheriting gotchas you didn't create and can't control.

Most end customers are fine with the vendor owning the infra layer — that's the deal they're making when they ask for BYOC.

That said, if a customer wants to bring their own VPC or existing infrastructure, Nuon supports that too via inputs.
