The Azure equivalent of Amazon S3 is Azure Blob Storage. Both store objects in flat containers (S3 buckets, Blob containers) with an HTTP API, multiple cost tiers, versioning, replication, and WORM locking.
- Account model. S3 buckets are top-level resources with globally unique names. Blob containers live inside a storage account, and the account sets the redundancy, default access tier, network rules, and some features (such as the hierarchical namespace) for every container in it.
- Redundancy. S3 Standard stores data across at least three AZs by default; One Zone classes and Express One Zone use a single AZ. On Azure you choose per account. LRS is a single datacenter, ZRS spans zones, and GRS/GZRS add an asynchronous copy in the paired region. Pick ZRS explicitly if you want S3-like zone resilience.
- Object types. S3 has one object type (with multipart upload). Blob Storage has block blobs (the S3 equivalent), append blobs (for logs), and page blobs (random-access, used by legacy unmanaged disks).
