S3 (Simple Storage Service) is AWS's object storage service — storing files (objects) of virtually any size and quantity, durably and scalably, accessible over the internet. It's one of AWS's most-used services, ideal for files, backups, static assets, data lakes, and more.
Cad é S3
S3 stores OBJECTS (files + metadata) in BUCKETS (containers):
→ store ANY amount of data, files of any type (up to 5TB each)
→ highly DURABLE (99.999999999% — "11 nines") and available
→ accessed via APIs/URLs (not a filesystem — it's object storage, key→object)
→ virtually unlimited scale; pay for what you store and transfer
