AWS Storage Explained | EBS vs EFS vs S3 | AWS Training

AWS offers three primary storage types: block, file, and object storage, each with distinct use cases and limitations. Block storage (EBS) is bootable and provides direct access to volumes, making it ideal for EC2 instances, but requires both the instance and EBS to be in the same availability zone 0:52. File storage (EFS) supports hierarchical file systems and multi-user access over a network, but cannot be used to boot an operating system 3:44. Object storage (S3) stores files as objects in a flat structure, without folders, and is not mountable or bootable—ideal for logs, media, and backups 5:16.
Key takeaways:
• Block storage (EBS) is bootable and must be in the same availability zone as the EC2 instance 0:52.
• File storage (EFS) allows network-based access and multi-user sharing but cannot boot an OS 3:44.
• S3 (object storage) uses a flat file structure with no folders and is not bootable, making it suitable for logs and media 5:16.
• S3 storage classes vary by cost, access speed, and durability: Standard (most expensive, immediate access), Standard IA (cheaper, infrequent access), One-Zone IA (cheaper, single-zone), Glacier Instant (low cost, immediate access), Glacier Flexible (cold start, 5–12 hours), and Glacier Deep Archive (cheapest, longest retrieval time) 13:03.
• S3 Intelligent-Tiering automatically selects the optimal storage class based on access patterns, with a monitoring cost per 10,000 objects 14:48.
Choose storage based on access frequency and availability needs: immediate access requires S3 Standard or Glacie

[Music] Hey there, I'm Michael from CodeCloud. Welcome to this lesson from our AWS cloud practitioner certification course. In this video, we'll help you build a strong foundation in cloud computing with AWS. So, if you want to learn more or go deeper, check out the full course details below and let's get started. In this lecture, I'm going to go over the different storage services available within AWS. Now, there's three different types of storage. We have block storage, file storage, and object storage. So, I'm going to go over each of these different types of storage, explain when you would want to use each one, what are the benefits, the pros and cons of each one, and then I'm going to go over the matching AWS service that provides that specific type of storage. So, now let's talk abou…
