An Ontological Approach to Designing a Microservice Architecture
Main Article Content
Abstract
Despite the widespread use of microservice architecture in the development of software systems, there is no formalized approach that ensures consistent and guaranteed interaction of microservices at the level of transmitted data, which leads to integration errors and complicates the maintenance of distributed systems. The purpose of the study is to develop an approach to the organization of microservices interaction based on ontological modeling, providing formalization of data structures and automated validation of messages. The paper presents a method for converting formal descriptions of data schemas into ontological models based on the GraphQL schema specification. This method allows you to automate the data validation process and reduce the number of integration errors. An ontological model has been developed that provides an analysis of dependencies between microservices and a mechanism for validating message contracts.
The practical significance of the work lies in achieving a consistent description of microservices, operations, and message formats as a result of using an ontological approach. The representation of the ontology in the form of a graph makes it possible to analyze the dependencies between microservices and simplifies the maintenance of large distributed systems.
