Microservices

In line with current digital transformations, the number of software applications in use by companies is continuously increasing. This particularly affects industrial enterprises, which face challenges due to their often complex business processes. A holistic and sustainable integration of these business processes requires a strong link between the different information systems used. In this context, application integration, also known as enterprise application integration (EAI), is becoming more important. Modern approaches such as the use of microservices offer a particularly flexible and efficient solution for seamlessly connecting different applications and thus promoting the agility and scalability of a company’s IT landscape.

The intensive use of the term microservice calls for a theoretical analysis of the technology. Since service-oriented architecture approaches have produced rather disappointing results, the focus should be on the advantages of microservices. This article questions which principles justify the use of microservices as a system architecture. So far, some of the advantages mentioned in the examined literature have not been further explained or defined. There is also a lack of key figures for measuring success.
