AWS వివిధ అవసరాల కోసం అనేక storage types ను అందిస్తుంది — S3 (object storage), EBS (block storage / EC2 కోసం disks), మరియు EFS (shared file storage). వాటి తేడాలను మరియు use cases లను అర్థం చేసుకోవడం ప్రతి workload కోసం సరైన storage ఎంచుకోవడానికి సహాయపడుతుంది.
మూడు ప్రధాన storage types
text
S3 (OBJECT storage) → files/objects accessed via API, virtually unlimited, durable:
→ for: files, backups, static assets, data lakes, anything accessed as whole objects
→ NOT a filesystem (no in-place edits; access by key); accessed over HTTP/API
EBS (BLOCK storage) → virtual disks ATTACHED to a single EC2 instance:
→ like a hard drive for an instance (boot volumes, databases, app data)
→ attached to ONE instance at a time (in one AZ); persists independently of the instance
→ for: an instance's filesystem, databases needing low-latency block storage
EFS (FILE storage) → a shared filesystem mountable by MANY instances simultaneously:
→ NFS file system; multiple EC2 instances mount it concurrently (shared access)
→ scales automatically; for: shared files across instances, content management, etc.
