    Blob storage

    Massively scalable object storage for unstructured data

    Scale up or down using Hot, Cool, Archive, or Premium storage

    Get scalable, cost-effective cloud storage for all your unstructured data. Pay only for what you use, and save money compared with on-premises storage options. Choose from among four storage tiers, depending on how often you’ll access the data. Store performance-sensitive data in Premium, frequently accessed data in Hot, infrequently accessed data in Cool, and rarely accessed data in Archive.

    Why choose Azure Blob Storage?

    All cloud object storage is not the same. Azure offers:

    Strong consistency

    When an object is changed, it’s verified everywhere for superior data integrity, ensuring you always have access to the latest version.

    Object mutability

    Get the flexibility to perform edits in place, which can improve your application performance and reduce bandwidth consumption.

    Multiple blob types

    Block, page, and append blobs give you maximum flexibility to optimize your storage to your needs.

    Easy-to-use geo-redundancy

    Automatically configure geo-replication options in a single menu, to easily empower enhanced global and local access, and business continuity.

    One infrastructure, worldwide access

    Make your unstructured data available to customers anywhere through REST-based object storage. With regions around the world, it’s ideal for streaming and storing media, whether it’s live broadcast events or long-term archive of petabytes of movies and television shows. Search for hidden insights in massive object storage, through big data analytics, and give access to the right people at the right time, no matter where they are.

    Any data, cloud scale

    Store any type of unstructured data—including images, videos, audio, documents, and backups—with proven technology at exabyte scale. Blob storage handles trillions of stored objects, with millions of average requests per second, for customers around the world. Blob storage also supports Azure Data Share, a simple and safe service for sharing big data.
