Software services, such as Web services, are emerging technologies to reuse software as services over the Internet by wrapping underlying computing models with XML, Software services are rapidly evolving and are expected to change the paradigms of both development and use of information systems. This article discusses the current status and challenges of software services technologies. We classify the software services technologies into two categories : platform and development technologies. On the platform technologies, we provide a service-oriented computing framework for publishing, finding and executing services over the Internet. The framework consists of number of technologies such as SOAP, WSDL and UDDI. Brokerage of services is discussed. On the service-oriented development technologies, we discuss two development models : business-driven and user-driven models. The software services are expected to enable more dynamic collaboration across the organizational boundaries, thus, demand us to re-think the way we organize corporation and business processes. Finally, a number of open issues are pointed out.
