Improving the effectiveness of monolith architecture to microservices migration using existing migration methods

Abstract

The theme of the transition from monolithic architecture to microservice is one of the key challenges of modern software engineering. This transformation allows for greater flexibility, scalability and adaptability of systems, but requires careful planning and consideration of numerous factors that affect the efficiency of migration. This study aims to improve the algorithm for determining the effectiveness of using methods for migrating monolithic systems to microservice architecture. Migration from monolithic architecture to microservice is a complex process involving significant technical and organizational challenges. Since monolithic systems often have a complex structure and relationships between components, the transition to a microservice architecture requires careful planning and selection of effective migration methods. The lack of a unified approach to assessing the effectiveness of different migration patterns makes the transition process difficult and risky.

The article is aimed at improving the algorithm for determining the efficiency of using migration methods from monolithic architecture to microservices. To do this, we compare existing migration patterns, such as the Strangler Fig Pattern, Branch by Abstraction, Parallel Run, Decorating Collaborator and Change Data Capture, according to the criteria: implementation time, test complexity, error risk, performance degradation and efficiency. The study uses methods of comparative analysis and quantitative evaluation of the effectiveness of migration patterns. For this, criteria are applied to assess the implementation time, testing complexity, possible risks, as well as the impact on system performance. In addition, scenarios are analyzed in which each template is most effective, which allows you to determine the optimal approaches to migration depending on the specifics of the project.

The obtained results allow not only a deeper understanding of the advantages and disadvantages of different approaches to migration, but also to form recommendations for choosing the optimal pattern, depending on the specifics of the system and business needs. The scientific novelty of the study is to create an algorithm that integrates these criteria to increase the efficiency of migration processes. The results of the work can be useful for software engineers, architects and managers planning the transition to microservice architecture, providing a structured methodology for evaluating and selecting migration methods.
