Modern enterprise systems are rapidly transitioning from monolithic architectures to cloud-native microservices-based systems to achieve scalability, resilience, and rapid deployment cycles. Container orchestration platforms such as Kubernetes, along with managed services like Amazon Elastic Kubernetes Service (Amazon EKS), have become foundational technologies for deploying high-availability distributed applications. This paper proposes a scalable cloud-native architecture leveraging Kubernetes and Amazon EKS to design, deploy, and manage microservices in production-grade environments.
The proposed architecture focuses on achieving high availability, fault tolerance, automated scaling, secure deployments, and efficient resource utilization. By integrating Infrastructure as Code (IaC), CI/CD automation, and DevSecOps principles, the system ensures continuous delivery and operational efficiency. Prior research highlights the increasing adoption of Kubernetes in enterprise environments and the need for automated infrastructure provisioning and compliance verification in cloud systems (Arya et al., 2024; Nagpal et al., 2024).
The study also incorporates disaster recovery strategies, security frameworks, and blue-green deployment mechanisms to ensure system reliability and minimal downtime. Experimental analysis and architectural evaluation demonstrate that combining Kubernetes with Amazon EKS significantly improves deployment consistency, reduces operational overhead, and enhances system scalability in distributed cloud environments.
