Microsoft has released a new set of features for Windows Azure Blob, that enables applications to store and manipulate large objects and files in the cloud. The blobs (files) can be up to 50GB in size for the CTP. All changes for this release ‘re versioned changes, using “x-ms-version: 2009-07-17”. All prior versions of commands executed against the storage system’ll continue to work, as we extend the capabilities of the existing commands and introduce new commands. The latest features added to Windows Azure include Update Blob with PutBlockList, Root Blob Container, and Shared Access Signatures for Signed URLs. Windows Azure testers’ll now be able to update the contents of specific blobs.
