Qualitative and quantitative comparison of Spring Cloud and Kubernetes in migrating from a monolithic to a microservice architecture

The microservice architecture has several advantages over conventional monolithic architectures, such as the ability to develop and deploy services independently and flexibility in dealing with bottlenecks. Most existing works in this field have focused on methodologies by which to divide monolithic systems into microservices, paying little or no attention to the target platform or migration tools, despite the profound effects that they can have on system migration. For a monolithic and service-oriented application, the go-to frameworks and platforms for migration to a microservice architecture are Spring Cloud and Kubernetes. This paper compares the pros and cons of the two approaches and presents experiments involving a stress-testing tool to elucidate performance and scalability under various conditions.
