In April 2026, AWS launched Amazon S3 Files, a service that allows you to mount an S3 bucket as a POSIX-compliant file system with zero or minimal migration effort. For organizations deeply invested in AWS, this offering seems like a natural evolution, turning the world's most popular object store into a shared file system with sub-millisecond latency.
But what exactly is S3 Files under the hood? What workloads does it truly excel at? And how does it compare to a purpose-built distributed file system like JuiceFS?
During this office hour, we'll talk about the architecture of S3 Files, its high-performance EFS storage tier, and its automatic write-back sync window. We'll then compare it side-by-side with JuiceFS in terms of things like metadata performance, write amplification, cross-cloud support, and cost structure. There are no perfect solutions, only trade-offs. By the end of this session, you'll know exactly how to evaluate your AI/ML and other workloads before settling on a storage solution.
