  • what do they use, or how do they do it..
    The big providers like AWS, GCP, Azure, all have fully custom solutions for the whole infrastructure. But there exist a number of open source projects which give you the ability to setup the basics (compute, storage, networking) on your own. A few such infrastructure projects I'm aware of: * Cloudstack * Openstack * Eucalyptus. Source: about 3 years ago
