Modernizing corporate applications is a strategic imperative for enterprises to stay competitive in a more digital and data-driven world. Traditional monolithic systems have serviced intricate corporate activities well in the past but often don’t fit today’s requirements for scalability, agility, resilience and speed of invention. Because they are tightly coupled, they are more complex to build, deploy and administer, which raises operational costs and hinders their response to changing business needs. Cloud-native computing has changed how we build and run programs to be elastic, automated and make the best use of resources in distributed environments. In this context, microservices architecture has developed as a major notion to decompose programs into smaller independently deployable services, which can enhance scalability, fault isolation and development efficiency. Kubernetes has evolved as the standard for automating the deployment, scaling, networking, and lifecycle management of containers. It offers an efficient solution for organizations to operate complex application ecosystems. In this paper we focus on the shift from monolithic business systems to cloud-native ecosystems based on Kubernetes and microservices. This article provides a comprehensive survey of the existing research, industrial approaches and real modernization activities to assess the architectural, operational and organizational impacts of the adoption of cloud-native technology. We study the impact of modernization methodologies, deployment strategies and implementation challenges on the performance, scalability, reliability and business agility of the system. Results indicate that organizations adopting microservices design on Kubernetes can achieve higher deployment frequency, better resiliency, improved resource utilization and greater agility to respond to evolving market needs. The change introduces problems in service management, security, observability and operational complexity that need to be planned and regulated in detail. The paper provides a broad view on enterprise modernization, including important success factors, best practices and architectural considerations for organizations embarking on cloud native transformation programs. The analysis shows that Kubernetes and microservices are the crucial technologies to construct sustainable, scalable and future-proof enterprise application ecosystems.
