Microsoft has previewed a new immutable storage capability for its Azure Storage Blobs, a move cheered by cloud-focused solution providers as a way to get clients in regulated industries to move their sensitive data to cloud storage.
Microsoft, in a blog post written by Mitra Sinha, principal product manager for Azure storage, unveiled the public preview of a WORM, or write-once-read-many, option for Azure Blobs.
The new WORM capability is targeted at businesses which need to retain and prove the integrity of business-related data to meet regulatory requirements from organisations, Sinha wrote.
"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," she wrote.
WORM for Azure Storage Blobs is useful for such workloads as regulatory compliance, secure document retention, and legal hold, Sinha wrote.
It features time-based retention policy support so that the data can be stored immutably for a specified time, legal hold policy support to hold data immutable until a legal hold is cleared, support for all storage tiers from hot to cool to archive storage, and configuration at the Blob Container level. The WORM capability is available at no extra charge, she wrote.
Solution providers said WORM for Blobs is a welcome feature for clients facing regulatory issues with their data, and in some cases gives Azure a leg-up on competitors like Amazon Web Services.
