Cloud computing is a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using internet technologies. Gartner defines the cloud infrastructure and platform services (CIPS) market as standardized, highly automated offerings, in which infrastructure resources (e.g., compute, networking and storage) are complemented by integrated platform services. These include managed application, database and functions as-a-service offerings. The resources are scalable and elastic in near-real time and are metered by use. Self-service interfaces, including a web-based user interface (UI) and an API, are exposed directly to the customer. The resources may be single-tenant or multitenant, and can be hosted by a service provider or on-premises in the customer’s data center.
Gartner defines managed hybrid cloud hosting (MHCH) as a standardized, productized offering that combines a cloud-enabled system infrastructure platform — consisting of a pool of compute, network and storage hardware — with cloud infrastructure framework software to facilitate self-service and rapid provisioning. In addition to offering this service from cloud infrastructure located in its own data center, the provider must offer a choice of using a hyperscale public infrastructure as a service (IaaS) provider or an Asian country-specific, large-scale IaaS provider. The infrastructure platform should be located both in a service provider's data center for the cloud-enabled system infrastructure (CESI) platform and in an Asia country for the public IaaS platform. It also requires the use of a standardized deployment across all service provider customers and leverages a single codebase.
Gartner defines unified communications as a service (UCaaS) as a cloud-delivered service that provides many of the same functions as premises-based unified communications (UC) solutions. The core capabilities of UCaaS offerings include those in the following areas: Telephony Meetings Messaging Software apps (formerly software clients) Communication APIs and SDKs Adjacent services
