Exploring Azure Blob Storage: Types, Tiers, and Benefits
Azure Blob Storage is Microsoft's object storage solution, purpose-built for storing massive amounts of unstructured data such as images, videos, backups, and log files.
Types of Blobs
- Block blobs — optimized for storing and streaming large files like documents, images, and videos
- Append blobs — optimized for append-only operations, ideal for logging scenarios
- Page blobs — optimized for frequent random read/write operations, used for VM disks
Access Tiers
- Hot tier — for data accessed frequently, offering the lowest access cost
- Cool tier — for infrequently accessed data stored for at least 30 days
- Archive tier — for rarely accessed data stored for at least 180 days, with the lowest storage cost but higher retrieval latency
Key Benefits
- Virtually unlimited scalability for unstructured data
- Lifecycle management policies to automatically transition data between tiers
- Strong durability through redundancy options like LRS, ZRS, and GRS
- Native support for static website hosting directly from a container
Matching each blob to the right access tier is one of the easiest ways to cut storage costs — moving cold, rarely accessed data to Cool or Archive tiers can reduce costs dramatically over time.
