Service provider (Ofer Abarbanel online library)

service provider (SP) provides organizations with consulting, legal, real estate, communications, storage, processing. Although a service provider can be an organizational sub-unit, it is usually a third party or outsourced supplier, including telecommunications service providers (TSPs), application service providers (ASPs), storage service providers (SSPs), and internet service providers (ISPs). A more traditional term is service bureau (esp. 1960s to 1980s).

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]
