Nowadays, it is already not enough for enterprise information system to provides simple automation of informational and computational business problems, a corporate information system must change as quickly as quickly company’s business requirements and business processes change. It was one of the main preconditions for the appearance of service oriented architecture, a.k.a. SOA. It is construed as a paradigm of distributed set of functionality, where each of them is represented as a service. The paper describes the main parameters of the quality of such services determined by different standards and offers the concept of functional reserve in order to provide guaranteed services quality when creating an application represented by a composition of services.Downloads
