Where do you put 40 TB of images that browsers fetch directly?
- AAmazon S3, where each image is an object served over HTTPS
- BAmazon EBS, with a volume per web server that grows as needed
- CAmazon EFS, with one shared mount that every web server reads
- DAn instance store, using the local disks of the serving instances
Why this is the answer
S3 is the fit whenever the data is whole files read over HTTP and the volume is open-ended: capacity is not something you provision, and objects can be served publicly or through CloudFront without a server in front. EBS volumes attach to one instance and must be sized in advance, EFS is for applications that need a POSIX file system rather than for public delivery, and instance store disks vanish with the instance.
