Platform as a service (PaaS) is a cloud offering that delivers application infrastructure (middleware) capabilities. PaaS capability can be delivered as provider-managed or self-managed, multitenant, or dedicated.

Business Process as a Service (BPaaS) delivers business process outsourcing (BPO) services sourced from the cloud and constructed for multitenancy. Services are often automated, and where human process actors are required, and less dedicated labor pool per client. The pricing models are consumption-based or subscription-based commercial terms. As a cloud service, the BPaaS model is accessed via Internet-based technologies.

Infrastructure as a service (IaaS) is a standardized, highly automated offering in which computing resources owned by a service provider, complemented by storage and networking capabilities, are offered to customers on demand. Resources are scalable and elastic in near real-time and metered by use. Self-service interfaces, including an API and a graphical user interface (GUI), are exposed directly to customers. Resources may be single-tenant or multitenant and are hosted by the service provider or on-premises in a customer’s data center.

Software as a service (SaaS) is owned, delivered, and managed remotely by one or more providers. The provider delivers software based on one set of standard code and data definitions consumed in a one-to-many model by all contracted customers at anytime on a pay-for-use basis or as a subscription based on use metrics.

Desktop as a service (DaaS) is an offering that provides users with an on-demand, virtualized desktop experience delivered from a remotely hosted location. It includes provisioning, patching, and maintenance of the management plane and resources to host workloads.
