Block vs Object Storage three ways to keep bytes

IN 10 SECONDS

Block storage (EBS) attaches raw disk sectors to a single machine (highest performance). Object storage (S3) stores flat files at a URL (unlimited scale, slower access).

GOTCHA Cloud block storage disks (EBS) can only attach to one virtual machine at a time. If you need shared directories, use file storage (EFS).

HOW FILE ACCESS DIFFERENCES FLOW

01 Block Access database reads raw block sectors (0x3A) directly from mounted cloud disk (EBS).

02 Object Access application pulls files by HTTP URL: GET s3://bucket/photo.jpg.

03 File storage (EFS) multiple virtual machines mount the same network folder (NFS) to share assets.
