Continuous Integration and Continuous Delivery/Deployment (CI/CD) constitute a fundamental paradigm in modern cloud-native and DevOps-driven software engineering. These practices automate code integration, testing, validation, and deployment processes, thereby enhancing development efficiency and reducing operational risk. As contemporary distributed software ecosystems increasingly adopt microservice-based, containerized, and edge–cloud architectures, CI/CD pipelines have become essential for ensuring rapid iteration, reproducibility, scalability, and system reliability. Consequently, the performance, scalability, and architectural design of CI/CD platforms significantly influence development velocity and overall system stability Although CI/CD platforms are widely adopted in industry, limited research has systematically evaluated their performance within complex distributed environments such as microservice-based Industrial IoT (IIoT) systems.
