An Approach for Reconstructing Applications to Develop Container-Based Microservices

الملخص EN

Microservices are small-scale services that can operate independently.

An application consisting of microservice units can be developed independently as a service unit, and it can handle individual logic without being affected by other services.

In addition, it is possible to rapidly distribute the configured microservices by a container, and a container orchestration technology that manages the distributed multiple containers can be realized; thus, it is possible to update and distribute the microservices separately.

Therefore, many companies are moving away from existing monolithic structures and attempting to switch to microservices.

In this paper, we present a method for reconstructing a monolithic application into a container-based microservice unit.

The microservices of data units are derived through the collection and analysis of monolithic design data.

Furthermore, we propose a method to generate a template script based on deployment design data so that the derived microservice and support distribution can be implemented in a container environment.

The results of a case study conducted verified that the container-based microservices deployed in this study work properly.

In addition, for the development of monolithic applications and the development of container-based microservices presented in this paper, we confirmed that developing on the basis of microservices is efficient by conducting execution time performance evaluation for API calls at various iterations.

Finally, we show that microservices constructed using the proposed method have higher reusability than those constructed using existing methods.
