Amazon FSx is a fully managed file storage service that allows users to deploy third-party high-performance file systems on AWS. It provides scalability, security, and integration with AWS services while reducing operational overhead.

FSx is similar to Amazon RDS but for file systems, allowing you to launch and manage different file storage solutions without handling the underlying infrastructure.
