Top 5 Cloud File Systems: Amazon EFS, Azure Files, GCP Filestore, NetApp Cloud Volumes, and More

📌 Introduction

In today’s cloud-native landscape, choosing the right file system is crucial for performance, scalability, and cost optimization. Unlike traditional on-prem file systems, cloud file systems offer shared, persistent storage with high availability, making them ideal for containerized apps, analytics workloads, and enterprise-scale operations.

In this article, we’ll explore the top 5 cloud file systems—Amazon EFS, Azure Files, GCP Filestore, NetApp Cloud Volumes, and a rising open-source alternative—CephFS. Let’s dive into their features, use cases, pros, and pricing structures.
