Optimized Strategy in Cloud-Native Environment for Inter-Service Communication in Microservices

Abstract

Cloud computing has become a prominent technology in the software development industry. The term “cloud-native” is derived from cloud computing technologies and refers to the development and deployment of applications in a cloud environment. In the software industry, most enterprise-grade software buildings use the microservice architecture and cloud natively, ultimately leading to an expansive development in the software development framework. Microservices are deployed in a distributed environment and function as independent services. However, they need to communicate with each other in order to fulfill the functional requirement. Additional latency will be introduced when communicating with other services. Hence, it will impact the overall application response time and throughput. This research proposes a solution for the aforementioned problem in the cloud-native environment. A Request-response-based TCP communication solution has been developed and tested in the cloud-native, containerized environment. Experimental results showed that the turnaround time of the proposed solution is shorter than that of traditional HTTP communication methods. Furthermore, the results summarize that both vertical and horizontal scaling are improving the overall performance of the systems performance in terms of response time. Conclusively, the proposed solution improved the microservice performance and preserved the existing cloud-native qualities, such as scalability, maintainability, and portability.
