Guided Notes
Storage: S3, EBS & EFS
Block, object, and file storage; EBS volumes and snapshots; S3 buckets, storage classes, and lifecycle rules.
Three kinds of storage
Slide 1 / 5• Block storage — a disk split into blocks; fast, for operating systems and databases. EC2 instance store (temporary, lost when the instance stops) and Amazon EBS (persistent). • Object storage — whole files with metadata, addressed by a key, virtually unlimited. Amazon S3. • File storage — a shared file system many servers can mount at once. Amazon EFS (Linux) and Amazon FSx (Windows, Lustre, and more).
