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). A more traditional term is service bureau. IT professionals sometimes differentiate between service providers by categorizing them as type I, II, or III. 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 ...

Outsourcing
Outsourcing is an agreement in which one company hires another company to be responsible for a planned or existing activity which otherwise is or could be carried out internally, i.e. in-house, and sometimes involves transferring employees and assets from one firm to another. The term ''outsourcing'', which came from the phrase ''outside resourcing'', originated no later than 1981. The concept, which ''The Economist'' says has "made its presence felt since the time of the Second World War", often involves the contracting of a business process (e.g., payroll processing, claims processing), operational, and/or non-core functions, such as manufacturing, facility management, call center/call center support. The practice of handing over control of public services to private enterprises (privatization), even if conducted on a limited, short-term basis, may also be described as outsourcing. Outsourcing includes both foreign and domestic contracting, and sometimes includes offshorin ...

Service Provider (SAML)
A SAML service provider is a system entity that receives and accepts authentication assertions in conjunction with a single sign-on (SSO) profile of the Security Assertion Markup Language (SAML). In the SAML domain model, a ''SAML relying party'' is any system entity that receives and accepts information from another system entity. Of particular interest is a SAML relying party that receives and accepts a SAML assertion issued by a SAML authority. An important type of SAML authority is the SAML identity provider, a system entity that issues authentication assertions in conjunction with an SSO profile of SAML. A relying party that consumes such assertions is called a ''SAML service provider'' (or simply ''service provider'' if the domain is understood). Thus ''a SAML service provider is a system entity that receives and accepts an authentication assertion issued by a SAML identity provider.'' See also * Security Assertion Markup Language (SAML) * SAML identity provider * SAML-bas ...

IT Service Management
Information technology service management (ITSM) is the activities that are performed by an organization to design, build, deliver, operate and control information technology (IT) services offered to customers. Differing from more technology-oriented IT management approaches like network management and IT systems management, IT service management is characterized by adopting a process approach towards management, focusing on customer needs and IT services for customers rather than IT systems, and stressing continual improvement. The CIO WaterCoolers' annual ITSM report states that business uses ITSM "mostly in support of customer experience (35%) and service quality (48%)." Context As a discipline, ITSM has ties and common interests with other IT and general management approaches, information security management and software engineering. Consequently, IT service management frameworks have been influenced by other standards and adopted concepts from them, e.g. CMMI, ISO 9 ...

Identity Provider
An identity provider (abbreviated IdP or IDP) is a system entity that creates, maintains, and manages identity information for principals and also provides authentication services to relying applications within a federation or distributed network. Identity providers offer user authentication as a service. Relying party applications, such as web applications, outsource the user authentication step to a trusted identity provider. Such a relying party application is said to be ''federated'', that is, it consumes federated identity. An identity provider is “a trusted provider that lets you use single sign-on (SSO) to access other websites.” SSO enhances usability by reducing password fatigue. It also provides better security by decreasing the potential attack surface. Identity providers can facilitate connections between cloud computing resources and users, thus decreasing the need for users to re-authenticate when using mobile and roaming applications. {{cite web , url = http ...

SAML 2
Security Assertion Markup Language (SAML, pronounced ''SAM-el'', ) is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: * A set of XML-based protocol messages * A set of protocol message bindings * A set of profiles (utilizing all of the above) An important use case that SAML addresses is web-browser single sign-on (SSO). Single sign-on is relatively easy to accomplish within a security domain (using cookies, for example) but extending SSO across security domains is more difficult and resulted in the proliferation of non-interoperable proprietary technologies. The SAML Web Browser SSO profile was specified and standardized to promote interoperability.J. Hughes et al. ''Profiles for the OASIS Security Assertion Markup Languag ...

Service System
A service system (or customer service system, CSS) is a configuration of technology and organizational networks designed to deliver services that satisfy the needs, wants, or aspirations of customers. "Service system" is a term used in the service management, service operations, services marketing, service engineering, and service design literature. While the term frequently appears, it is rarely defined. One definition of a service system is a value coproduction configuration of people, technology, internal and external service systems connected via value propositions, and shared information (language, laws, measures, etc.). The smallest service system is a single person and the largest service system is the world economy. The external service system of the global economy is considered to be ecosystem services. Service systems can be characterized by the value that results from interaction between service systems, whether the interactions are between people, businesses, or n ...

Service Bureau
A service bureau is a company that provides business services for a fee. The term has been extensively used to describe technology-based services to financial services companies, particularly banks. Service bureaus are a significant sector within the growing 3D printing industry that allow customers to make a decision whether to buy their own equipment or outsource production. Customers of service bureaus typically do not have the scale or expertise to incorporate these services into their internal operations and prefer to outsource them to a service bureau. Outsourced payroll services constitute a commonly provisioned service from a service bureau. The business model question One writer described the ideal service bureau customer as only needing vanilla: very little customization per customer. The phrasing is catering "to the bell curve of customer requirements." If strawberry banana is needed, it is important to ask: :Did they develop their own platform or license or purchase it? ...

IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (I ...

Service-oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies. Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services. A service has four properties according to one of many definitions of SOA: # It logically represents a repeatable business activity with a specified outcome. # It is self-contained. # It is a black box for its consumers, meaning the consumer does not have to be aware of the s ...
