Azure Blob Storage is Azure’s fundamental object-storage service: a flat namespace for durable, geo-redundant storage of unstructured data and Iceberg table files. Applications access blobs over HTTPS through the REST-based Blob API or, in some configurations, an S3-compatible API. section 5.4.5
Its practical architecture combines storage flexibility with operational integrations:
- Hot, Cool, and Archive tiers align storage cost with access frequency, including lifecycle transitions for older Iceberg data. section 5.4.5
- Event Grid and Azure Functions support event-driven ingestion, processing, and lifecycle workflows. section 5.4.5
- ADLS Gen2 extends Blob Storage with hierarchical namespaces, filesystem semantics, atomic renames, Azure AD authentication, and POSIX-style ACLs. section 5.4.5
