1. Introduction

Advanced development and deployment techniques guaranteeing both scalability and security have been required by the increasing complexity and size of enterprise systems, hence driving their adoption. Robustness, large libraries, and strong community support have made full-stack Java frameworks a popular alternative for creating enterprise-grade applications. However, traditional software deployment methods, which often involve manual steps and monolithic releases, pose significant challenges including prolonged downtime, increased likelihood of deployment failures, and potential security vulnerabilities that can expose critical business data.

Automation via Continuous Integration and Continuous Deployment (CI/CD) pipelines has become more popular to circumvent these constraints. By use of CI/CD, the process of building, testing, and deploying applications is automated, therefore allowing quicker and more consistent delivery cycles. Even automatic deployments can pose dangers, however, when new versions are deployed straight into production settings, affecting big user bases with unanticipated faults or performance decline.

This study concentrated on combining canary testing—a progressive deployment approach that gradually exposes a new release to a subset of customers before a complete rollout—with CI/CD pipelines. In a controlled setting, canary testing allows early identification of performance problems, security concerns, or functional flaws, hence greatly lowering the danger of widespread failures. Canary testing improves both dependability and user experience during application changes by progressively redirecting traffic and tracking system health.

This paper investigated how the combination of CI/CD automation with canary testing enhances deployment efficiency, application scalability, system resilience, and security compliance in the context of full-stack Java enterprise applications. Characterized by the use of containerization, orchestration, service meshes, and automated security scanning integrated into the delivery pipelines, the year 2025 marks a period of maturity in DevOps tools and methods.

The project included creating a prototype full-stack Java application and executing a CI/CD process with automated build, test, and deployment phases with integrated canary testing. Measured and examined were key performance parameters including system latency, error rates, security vulnerability metrics, mean time to recovery (MTTR), and deployment frequency. The results showed significant changes over baseline manual deployment methods, hence stressing the necessity of automation coupled with canary testing for modern business application delivery.

This study adds to the developing body of knowledge on DevOps best practices by offering useful ideas for companies trying to automate scalable and safe full-stack Java application deployments, hence reducing risk and maximizing operational continuity.

2. Literature Review

Renuka and Pandian (2024) We examined innovative cloud automation processes designed for CI/CD pipelines. Emphasizing how advanced orchestration and pipeline automation lowered manual involvement and sped release cycles, their research underlined the advancement of automation solutions enabling smooth integration and delivery processes. This corresponded with the fundamental goal of automating complete-stack Java application deployments to increase efficiency and scalability.

Chandramouli (2022) by investigating DevSecOps deployments in microservices architectures, I helped to clarify security integration in contemporary deployment pipelines. Focusing on service mesh technologies, his study emphasized the need to include security checks and compliance validation across the deployment lifecycle. Essential for safeguarding enterprise applications in production settings, this effort helped to include security practices into CI/CD pipelines. A key concern handled by canary testing via controlled, incremental releases.

Nawagamuwa (2023) studied many IaC frameworks for serverless application testing on AWS, offering a comparative analysis of their features and constraints. This assessment highlighted the need of infrastructure automation to enable scalable deployments and consistent testing environments—

fundamental to carrying out automated CI/CD processes that might be modified for full-stack Java applications. In cloud settings, Infrastructure as Code (IaC) frameworks transformed the way infrastructure was provisioned and controlled.

Brikman (2022) In his pragmatic Terraform manual, described how declarative infrastructure management guaranteed consistency, repeatability, and version control of cloud resources. Terraforms approach to IaC exemplified the automation tools that worked smoothly with CI/CD pipelines, enabling the dynamic provisioning of scalable infrastructure to meet enterprise application workloads, particularly those incorporating canary testing approaches.

Sangapu, Panyam, and Marston (2022) offered a thorough guide on updating programs under Google Cloud settings. Their report explained the reasons behind application modernization—including containerization, microservices adoption, and CI/CD implementation—which together helped to enhance scalability and operational agility.

The practices they discussed mirrored the themes of automation and incremental deployment critical for secure and resilient full-stack Java enterprise applications.
