Global File Systems: An In-Depth Guide to Amazon FSx

1. Introduction to Global File Systems

A Global File System is a network file system that allows multiple clients, potentially spread across different geographical regions, to access and manage data simultaneously. Unlike traditional file systems, which are limited to a single server or local area network (LAN), global file systems support distributed environments with high availability, scalability, and performance.

In the cloud, global file systems enable seamless data sharing, collaboration, and real-time access across data centers, offices, and even remote teams.

Amazon FSx is a fully managed service that provides scalable, high-performance file systems built on popular file system technologies, including Windows File Server, Lustre, and NetApp ONTAP. It supports both Windows and Linux environments, making it versatile for various applications.
