A GIS team debates Amazon EFS versus Amazon S3 for shared working files. Which contrast best captures the difference at Cloud Practitioner depth?
Select an answer to reveal the explanation.
Short Explanation
If the app expects a real file system—open, lock, many writers—lean toward EFS. If it speaks put/get object APIs to a data lake or asset store, that is S3. Same cloud, different storage personalities; do not treat the logos as interchangeable.
Full Explanation
Amazon EFS presents a shared file system suitable for concurrent POSIX-style access from compute clients. Amazon S3 stores objects addressed by key through an object API and is not a general-purpose shared file system replacement for applications that expect file-system semantics. Choosing between them depends on access pattern: file mounts and locks versus object put/get for lakes and content stores.
