Finance:Service provider
A service provider (SP) is an organization that provides services, such as consulting, legal, real estate, communications, storage, and processing services, to other organizations. Although a service provider can be a sub-unit of the organization that it serves, it is usually a third-party or outsourced supplier. Examples include telecommunications service providers (TSPs), application service providers (ASPs), storage service providers (SSPs), and internet service providers (ISPs).[citation needed] A more traditional term is service bureau.
IT professionals sometimes differentiate between service providers by categorizing them as type I, II, or III.[1] The three service types are recognized by the IT industry although specifically defined by ITIL and the U.S. Telecommunications Act of 1996.
- Type I: internal service provider
- Type II: shared service provider
- Type III: external service provider
Type III SPs provide IT services to external customers and subsequently can be referred to as external service providers (ESPs)[2] which range from a full IT organization/service outsource via managed services or MSPs (managed service providers) to limited product feature delivery via ASPs (application service providers).[3]
