Service is a term that is used in the technical concepts in informatics, ICT and software in a different meaning than in economics and management. Service in IT concept means provided technical means - software logic or functionality that has intelligible value, utility and output for the customer (user). These services are used by users without knowing how and what it provides them - only output or interface interest them. (E.g. the user’s ability to print to a network printer is the result of the print server service.)
Software service in practice: The boundary between the purely technical and economic concept of the term service is not fixed. There are a number of software services provided on a commercial basis, which exist due to boom of different XaaS, cloud approaches and web applications. For example, different mail services, office software and other application software that are provided commercially.
Software services are also used in the development, design and software operation for encapsulating logic of the applications / software, i.e. for the designs of systems based on services (SOA). In the technical design of such architecture explicitly machine-machine services, i.e. web services are then used.
Note: In practice, the term IT services is used, which doesn’t have technical, but process meaning (it is used for services provided by the IT department or IT provider).
