In addition to that it would scale automatically — no setting a storage size — with however much data you used, just like their simple storage service (S3). It was called Elastic File System (EFS). However, elastic block storage (EBS) is still used by most to mount operating systems and often even for file storage (partially due to legacy use and since it is seen as more stable). So what happens when you reached your EBS limit? In the past it was no different than running out of hard drive space on a personal computer (or Mac). Most people panicked, freaked out, panicked some more, then started the long process of adding a new, larger drive (EBS volume) and copying all the existing data over from the old drive or adding a new drive then altering a bunch of software code to split where it can find the data.
