Advanced Technologies to Support Service Discovery in Service-Oriented Systems

The development of information technology encourages the service industry to revolutionize service-oriented businesses. Various service industries provide web-services as IT services and register it to several service directories, so other parties can use and integrate these services into existing systems to create more value. Performing service discovery from a collection of services in the service directory is a challenge that must be resolved. Understanding the latest technology to support service discovery could help them determine the technology that can be used. This article presents a review of previous studies related to service discovery methods carried out on service-oriented systems. It summarizes selected previous related studies and categorizes them based on qualitative approaches. The aim is to present some of the latest research and provide a comprehensive vision of designing service discovery engines. This paper provides theoretical contribution and the understanding related to service discovery from previous studies through the systematic literature review. Thirty-eight articles were selected based on search results and then reviewed. It can be used as a guide to build the service discovery engine for service-oriented system.

I. Introduction

Web-service is main component that plays a role in the development of service-oriented system. Using service composability principle, it can be reused in multiple purposes. IT services in the form of web-services (internet-based application programming interface) provided are not always developed by themselves, but also can be provided by others. At present in general, the services provided can be divided into two types 1.) SOAP-based service and 2.) RST-based service [1]. Programmable Web as the largest internet-based API directory (https://programmableweb.com) and community reported that APIs growth faster in 2019 than previous years. It stated that since January 2015, the number of average new APIs added is about 168 per month. This growth also shows the industry’s increasing need for APIs to fulfill its service-oriented systems. Based on data collected through a service repository called Programmable Web until March 2020, among more than 21,135 registered services, 82.9 percent of them are RST-based. Leveraging service directories to find suitable services to support business service automation is a challenge that has to solve.
