Storage
Object, block, and file storage patterns.
6 terms
- Elastic Block Store (EBS)
AWS's network-attached block storage for EC2 — persistent virtual disks that live independently of the instance. The durable disk under your databases and boot volumes.
- Elastic File System (EFS)
AWS's managed, elastic NFS — a shared filesystem many instances mount at once, growing and shrinking automatically, priced well above block or object storage.
- Glacier Deep Archive
AWS's cheapest storage tier — roughly $1 per terabyte per month — for data you must keep but almost never read, with retrieval measured in hours.
- Object Storage
Cloud storage that keeps files as objects in flat buckets accessed over HTTP — cheap, effectively unlimited, and the backbone of cloud data.
- S3 Object Lock
A compliance storage parameter enforcing write-once-read-many retention windows on object storage buckets.
- Simple Storage Service (S3)
AWS's foundational object store — eleven nines of durability, virtually unlimited scale, and the storage-class and egress decisions that decide your bill.
