Welcome back.

In this video, we're focusing on managed file storage solutions, namely Amazon FSX and Azure Files. Because for organizations operating across both AWS and Azure, providing consistent high-performance and accessible file shares is a common challenge.

Let's start with Amazon FSX. Rather than a single service, it's best to think of FSX as a family of fully-managed, high-performance file systems. This is its defining characteristic. AWS gives you the power to choose a specific, popular file system and runs it for you as a managed service, ensuring native compatibility and performance.

The portfolio is rather impressive. If your enterprise is built on Windows-based applications, Amazon FSX for Windows File Server provides a fully-managed native Microsoft Windows file system. It includes features like SMB support, Active Directory integration, and distributed file system name spaces, making it a seamless lift-and-shift solution for your corporate applications.

For high-performance computing, machine learning, or media processing workloads, there's Amazon FSX for Lustre. Lustre is a world-renowned parallel file system and FSX makes it easy to spin up, delivering massive throughput and sub-millisecond latencies for your most demanding compute jobs.

Perhaps most compelling for multicloud and hybrid scenarios is Amazon FSX for NetApp ONTAP. This service brings NetApp’s popular ONTAP file system to AWS, which offers data management features like SMB and NFS access, high-performance SSD storage with automatic tearing to lower cost capacity pools, and tools like SnapMirror for data replication between on-prem NetApp environments and AWS. This makes it an exceptional choice for disaster recovery and data migration.

And then we finally have FSX for OpenZFS, which provides a feature-rich and highly performant file system for Linux-based workloads, leveraging the power of the ZFS file system. The key takeaway for FSX is its specialization. You choose the exact file system technology your applications are built for, and AWS manages the underlying infrastructure.

Now, while FSX offers a portfolio of distinct file systems, Azure Files provides a more universal, simplified file share service. It delivers fully-managed file shares in the cloud that are accessible via two industry-standard protocols — Server Message Block (or SMB) for Windows, Mac OS, and Linux clients; and NFS (or Network File System), primarily for Linux workloads.

A major advantage of Azure Files is its simplicity and broad accessibility. You can create a file share and mount it directly on a cloud VM or an on-prem machine without complex setup. It offers several performance tiers, including premium tier — which is SSD-based, and this is for latency-sensitive workloads. Then you have standard HDD-based tiers, like transaction-optimized, hot, and cool, for less demanding use cases and archival.

Where Azure Files truly shines in a hybrid context is with Azure File Sync. This feature is useful for organizations with distributed offices or a large on-prem footprint, because you can install the Azure File Sync agent on a local Windows Server and turn it into a fast local cache of your Azure File share. This provides low latency access to frequently-used files while tiering less-used data to the cloud.

This optimizes on-prem storage. Changes made locally are then automatically synced to Azure and propagated to any other synced servers, creating a globally consistent file set. This is ideal for centralizing file services for remote offices, and enabling cloud-based backup and disaster recovery.

When choosing between these services for a multicloud strategy, the decision is going to hinge on your specific requirements. Amazon FSX is probably the better choice if your applications demand the native features and performance of a specific file system. Migrating a complex Windows application? FSX for Windows File Server is a perfect fit. Need to replicate your on-prem NetApp data to the cloud? FSX for ONTAP is made for that job.

Azure Files, on the other hand, excels in simplicity and hybrid integration. If you need a straightforward protocol-based file share that works across different operating systems and seamlessly extends your on-prem environment, Azure Files with Azure File Sync is a powerful and easy-to-manage solution. It's less about a specific file system technology and more about providing universal, centrally-managed file access.

In essence, your choice reflects a strategic decision. Do you need a managed version of a specialized file system? In that case, you'd use FSX. Or do you need a universal file share with best-in-class hybrid caching capabilities? In that case, you might use Azure Files. Understanding this fundamental difference will allow you to build a file storage architecture that effectively bridges your on-prem data centers and your multicloud deployments.
