High Resilient Messaging Service for Microservice Architecture

Abstract

Fundamental structure of a software system is called software architecture. Software architectures are helpful in systematic software development. One such software architecture is microservice architecture. This architecture breaks down the entire software system into smaller components each of which work independently. The microservice architecture is being widely adapted in software industries due to its reliability, scalability and easier maintenance. But breaking down a system into smaller, independent components that use different tech stacks and message formats gives rise to complex communication between the components. This paper proposes a new messaging service that allows communication between services with ease. The new messaging service uses distributed streaming platforms like Apache Kafka to decouple the messaging between services. It also uses Apache Camel to provide functionalities such as message schema transformation and schema validation; these functionalities allow the services to communicate with each other with only a few lines of code. The result is a new state of the art messaging service that can be easily integrated with producer and consumer services. The paper also discusses where the new messaging service is more suitable. The performance metric used here is the number of additional lines of code required on the producer or consumer side for using this messaging service. The results are, almost thirty percent to sixty percent reduction of code required for integration on the producer side and nine percent to forty percent reduction of code required for integration on the consumer side.

Optimized Strategy for Inter-Service Communication in Microservices

“…With this concept, they guarantee the message delivery to the client. Sanjana et al researched the highly resilient inter-process communication service for the microservice architecture [24]. In their implementation, they have used the Kafka message broker and have enabled the pub/sub messaging style to do the interservice communication.…”
