It also enables fast and efficient editing and merging of the same media by multiple users.

First party Microsoft services like Azure Site Recovery, Azure Backup, as well as many third-party developers have implemented industry-leading innovations using page blob’s REST interface.
Following are some of the unique scenarios implemented on Azure: Refer to the following document to get started with developing using page blobs.
