Cloud Infrastructure Providers deliver on-demand compute, storage, networking, and platform services consumed as a utility — typically metered and billed on usage. Core capabilities include virtual machines and bare metal, managed container and Kubernetes services, object and block storage, networking and virtual private clouds, managed databases, identity and access management, global regions and availability zones for resilience, and a broad catalog of higher-level managed services. Hyperscalers (AWS, Microsoft Azure, Google Cloud Platform) dominate the market; regional and specialized providers (Oracle Cloud, IBM Cloud, DigitalOcean, Hetzner, Linode) serve niches where compliance, pricing, or geographic presence matters.
