Public preview: Immutable storage for Azure Storage blobs

Published date: June 19, 2018

Financial services organizations regulated by entities like SEC, CFTC, FINRA, IIROC, and FCA are required to retain business-related communication in a Write-Once-Read-Many (WORM) or immutable state that makes it non-erasable and non-modifiable for a certain retention interval. The immutable storage requirement isn't limited to financial organizations. It also applies to industries such as healthcare, insurance, media, public safety, and legal services.

The public preview of immutable storage for Azure Storage blobs addresses this requirement. The feature is now available in all Azure public regions. Through configurable policies, users can keep Azure Blob storage data in an immutable state where blobs can be created and read, but not modified or deleted.

For more details on the feature, see the Microsoft Azure blog.
