The most industrialized countries have entered a post-industrial era where their prosperity is largely created through a service economy. There is a clear transition from a manufacturing based economy to a service based economy. In the Internet of Services (IoS) vision services are seen as tradable goods. Business services are one major asset in this context. Since they are inherently different from e.g. web services, we argue that there is a need for a specialized monitoring approach. In this paper we describe the differences between technical services and business services and discuss a number of challenges regarding their monitoring requirements. Keywords Business service, monitoring, Internet of Service, Web services, e-services and marketplaces.
