If we have an account with the public cloud vendor and we good to go, also then the cloud operator kept multiple option which allowing us to pick and choose right tools and solution according to our requirements. The public cloud vendors like AWS, Azure, GCP create this infrastructure multiple places around the globe and they can maintain their data centres by their own we just need to pay as what we used.
