Automatic AWS Account Onboarding

I built a solution with CloudFormation and AWS Service Catalog for a former client, enabling customers to easily create a new AWS account via Control Tower and an account vending machine. It was the only step necessary as the accounts created were already usable as they were automatically connected to central SSO and our Terraform deployment pipeline. Depending on the organizational unit in which the account was created, stricter security guardrails were set via SCP, configuration, and conformance packs.
