Object Store

• Scalable storage solution for storing unstructure data at internet scale
• Objects in a object store are immutable
• It can only be replaced, but never appended
• Access through either an SDK or the provided REST API
• Low throughput/IO performance compared to distributed file storage

Buckets

• It's store in containers called Buckets (not file/folder structure)
• There is no limit to the number of objects we can store in a bucket
• High file size limit (~5-10 TB)

Versioning

• Providers versioning out of the box
• It's possible to rollback to a previous state

REST API Interface

• Provide an HTTP + Rest API interface out of the box
• Useful for delivering static web content directly

Tiering

• The stored files have a tier for performance/costs tradeoffs

• Standard (hot access)

• Nearline (infrequent access)
• Coldline (very infrequent access)
• Archive (rare access)
