FSx File Gateway – Designing Networks for Complex Organizations – SAP-C02 Study Guide

FSx File Gateway

Amazon FSx File Gateway is a recent addition to the AWS Storage Gateway family to provide access to Amazon FSx for Windows File Server file shares on AWS from your on-premises environment. The idea is very similar to S3 File Gateway, which is that you can access the data on AWS through either a physical hardware appliance or a software appliance that you deploy on-premises either on VMware ESX, Microsoft Hyper-V, or a Linux KVM hypervisor (but also on Amazon EC2 instances, should you need to).

There are a few major differences from the S3 File Gateway service as outlined below:

  • Your files, managed through FSx File Gateway, will be available through the SMB protocol only (you cannot use NFS).
  • You need to have previously deployed an Amazon FSx for Windows File Server filesystem in your AWS environment.
  • You must have access via VPN or DX from your on-premises environment to that Amazon FSx for Windows File Server filesystem on your AWS environment.

For the above reasons, the use cases for each gateway type are also slightly different.

You would use Amazon S3 File Gateway when you want to access files you have stored on S3 from on-premises or want to make files you store on-premises available on S3 for further processing on AWS. In this case, you can then leverage all the services AWS provides to run all sorts of data analytics, including machine learning capabilities, to analyze the data on S3.

You would rather use Amazon FSx File Gateway when you want to move on-premises network file shares accessed through the SMB protocol to the cloud and keep accessing them seamlessly from your on-premises environment. Think of cases such as user home directories, team file shares, and so on.

See the following diagram for an illustration of how Amazon FSx File Gateway works:

Amazon FSx File Gateway is integrated with AWS Backup, so you can also manage and automate backups centrally, like Amazon S3 File Gateway. Additionally, you can activate Microsoft snapshotting technology and Microsoft Windows Shadow Copy on your version of Amazon FSx for the Windows File Server filesystem to allow users to easily view and restore files and folders on your file shares from a snapshot.
