So S3 is an object store, and the keyword here is very inexpensive general-purpose storage. In addition to S3, Amazon has a service called EFS or elastic file storage. This is a scalable file store. It has strong consistency and file locking, and it can be associated with many or multiple EC2 instances. So I often get asked the question, why would you use EFS rather than S3? And let me just add the third one, and then we'll come back and answer that. So elastic block storage is a local block or file store, has the lowest latency, and it connects to a single EC2 instance. Okay, so it's pretty clear why you'd use EBS series that with EC2. S3 is the generic storage, so what's EFS for? EFS designed for situations where you want to have shared file storage that is a scalable file system. When we go back to our mapping, we think of whether we are going to lift and…
