What is Amazon FSx used for?

Amazon FSx is specifically designed to provide fully managed file systems, which offer a simple and scalable way to store and access data. This service supports various file systems, including Windows File Server and Lustre, catering to diverse workloads and file storage needs. FSx integrates seamlessly with other AWS services, enabling users to easily leverage their file systems within applications without having to manage the underlying infrastructure.

With FSx, users benefit from automatic backups, replication across Availability Zones, and built-in security features such as encryption at rest and in transit. This functionality allows organizations to focus on their applications rather than the complexities of file system management, ensuring high availability, durability, and performance tailored to specific workloads.

The other options do not align with the purpose of Amazon FSx. For instance, virtualization solutions are typically provided by AWS services like Amazon EC2. Similarly, relational database management is the domain of services like Amazon RDS, while creating serverless applications is primarily the focus of AWS Lambda and DynamoDB.
