If you are already using Cloudflare that is correct, if you don’t that is an alternative.
Adding another vendor into your stack can often come with none engineering complexity (e.g. data protection forms, contractual requirements from customers another vendor you need to work with, etc.) so this is an alternative to stay in AWS when you already use it.
