S3 vs EBS vs EFS.

In Simple Words:

  • S3 (Object Storage): Unlimited storage accessible globally via REST API. Ideal for files, media, backups, and data lakes.
  • EBS (Block Storage): Virtual hard drive attached to a single EC2 instance in one AZ.
  • EFS (File Storage): Shared POSIX file system concurrently mountable by thousands of EC2 instances and Lambdas across multiple AZs.
