EBS  --------> 1 EC2 Instance is mapped to EBS - Block Level Storage

EFS ----------> Multiple EC2 Instances - Mounted to this File System - Common across multiple Apps

The main differences between EBS and EFS is that EBS is only accessible from a single EC2 instance in your particular AWS region, while EFS allows you to mount the file system across multiple regions and instances.

S3 -->  S3 is Object Level storage. S3 is not limited to EC2, Its linked to CloudFront through which many Media etc are hosted there.
