Addressing Persistent Storage Challenges in Kubernetes Environments

Abstract

The widespread adoption of Kubernetes as a cornerstone for container orchestration highlights the platform's robust capabilities in managing complex, distributed applications. However, an area that consistently presents challenges is the integration of persistent storage solutions. This review paper examines the persistent storage challenges in Kubernetes environments, focusing on the key issues of volume management, data durability, and scalability across diverse infrastructures. Through an extensive literature review, the paper aggregates findings from various studies, revealing common obstacles and innovative solutions in this field. It analyzes how Kubernetes handles stateful applications via Persistent Volumes (PVs), Persistent Volume Claims (PVCs), and StorageClasses, and evaluates the effectiveness of these mechanisms in real-world scenarios. Moreover, the paper delves into the advancements in Container Storage Interface (CSI) drivers and their role in enhancing storage flexibility and operator ease. By synthesizing current research, this review not only outlines the persistent issues but also highlights emerging trends and potential future directions in Kubernetes storage management. It serves as a critical resource for developers, IT professionals, and organizations aiming to leverage Kubernetes for applications requiring reliable and scalable storage solutions.
