Storage Gateway vs FSx

• Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. Storage Gateway provides a standard set of storage protocols such as iSCSI, SMB, and NFS, which allow you to use AWS storage without rewriting your existing applications. It provides low-latency performance by caching frequently accessed data on premises, while storing data securely and durably in Amazon cloud storage services.

• For Windows-based applications, FSx provides fully managed Windows file servers with features and performance optimized for "lift-and-shift" business-critical application workloads including home directories (user shares), media workflows, and ERP applications.

• If you have Linux-based applications, EFS is a cloud-native fully managed file system that provides simple, scalable, elastic file storage accessible from Linux instances via the NFS protocol.

• For compute-intensive and fast processing workloads, like high performance computing (HPC), machine learning, EDA, and media processing, FSx for Lustre, provides a file system that’s optimized for performance, with input and output stored on S3.
