Ritu, Shruti Arora, Aanshi Bhardwaj, Ashima Kukkar, Sawinder Kaur · 2024
This study investigates the practical aspects of evaluating the efficiency and performance of Representational State Transfer (REST) and gRPC communication protocols in microservice-based systems. Microservices revolutionize software architecture by enabling scalable applications through independently deployable services. However, effective communication between these services is crucial for maintaining system responsiveness and reliability. The paper takes a hands-on approach, drawing insights from real-world implementations and experiments. It offers a pragmatic overview of microservices architecture, highlighting the pivotal role of communication protocols in facilitating seamless interactions among distributed components. Furthermore, the study delves into the technical intricacies of REST and gRPC, exploring aspects such as message formats, serialization mechanisms, and transport protocols. Through empirical analysis, the paper evaluates the latency performance of REST and gRPC across various communication tasks under different workloads and network conditions. These insights provide practical guidance for developers and architects in selecting the most suitable communication protocol based on specific project requirements and performance constraints, ultimately enhancing microservice communication efficiency and reliability.
