The need for integration arises when companies start considering “boundary-less” information flows across a plateau of multiple enterprise information systems. Adding a new application to the system or replacing one of the existing applications requires the establishment of interfaces with a specific software tool for each of them. The classical way to solve this problem in a large-scale organization is to use a central integration platform based on service-oriented architecture (Service-Oriented Architecture (SOA)). In this work, we forecast the increase of granularity of services and application of micro-services to enhance traditional SOA in the prototypes of industrial internet and Web 3.0.
