AWS offers multiple cloud services for storage : 1. Simple Storage Service (S3) 2. Elastic Block Storage (EBS) 3). Elastic File Service (EFS) and more. If you have been reading various documents and comparisons and still confused, I wrote this to hopefully clear things up a tad.
- S3 (Simple Storage Service - object): if you have big files, want to share it EXTERNAL TO AWS with many others in the outside world, can use HTTP to access, does NOT need to be attached to an EC2 instance
- EBS (Elastic Block Storage - block): fast storage for your EC2 compute to use, usually SSD and NVMe based
- EFS (Elastic File Service - file): share data (pictures, document, ...) using files INTERNALLY WITHIN AWS, such as between EC2 instances
