Automating Scalable and Secure Enterprise Applications with Full-Stack Java: CI/CD Integration with Canary Testing

Focusing on the integration of Continuous Integration and Continuous Deployment (CI/CD) pipelines with canary testing techniques, this paper investigated the automation of scalable and secure enterprise systems created with full-stack Java. The study looked at changes in deployment frequency, system performance, dependability, and security posture by means of a thorough DevOps architecture. Apart from a notable drop in security vulnerabilities, the results showed notable improvements in deployment efficiency, less downtime, and quicker recovery times. By allowing incremental rollouts and early problem detection, canary testing showed efficacy in risk reduction, hence guaranteeing better system stability. The combination of security automation and compliance and vulnerability monitoring was made even stronger by it. The research confirms that for modern enterprise application delivery, combining CI/CD automation with canary testing is a strong strategy since it balances agility with operational resilience.
