Bootstrapping a cloud estate is called "Day Zero". Tasks include things like creating the resources for an initial IaC statefile, which in turn is used to setup the scaffolding for larger deployments. Some day zero resources are temporary and can safely be removed.
Also initial high level "root" keys are created and safely stored away in case a break-glass emergency ever happens.
