An Infrastructure as a Service (IaaS) is a cloud based service that helps companies build and manage their data as they grow, paying for the storage and server space that they need to build hardware or software without having to actually host and manage on-site servers themselves.
Popular IaaS solutions are DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, and Google Compute Engine (GCE).
