How can I share VM disk snapshots cross tenant efficiently?

I want to share VM snapshot outside my tenant, I see this can happen by exporting the snapshot then using the generated URL to copy the snapshot to the other tenant storage account, the problem is that I'm not seeing this as a scalable approach.

I'm using azure GO SDK and the blob storage startCopyFromUrl is very slow.

I also tried the shared image gallery approach in which I create an image version from snapshot and share it with another tenant (RBAC sharing) but I couldn't create a disk from image, I was only able to create VM.

What's the best and efficient way to share my snapshot using azure GO SDK?

Thanks

@Abed Ewiwi

The StartCopyFromURL function is implemented using the Copy Blob Rest API and hence is limited by constraint described in Remarks section. Most notably the fact that a destination blob cannot have multiple pending copy blob operation at the same time which limits the level of parallelism that can be supported.

You should consider using the AzCopy tool that support concurrency and parallelism.

@KarishmaTiwari-MSFT yes I'm aware of azcopy tool but It couldn't work for me because of :

azcopy is a CLI tool I can't ship it with my program nor I can exec.command within my program.

Even when trying a dummy app in which I'm trying azcopy 26 snapshots distributed in azure storage (not under the same folder, every time exporting a snapshot I got a url in different storage/container in the azure storage) , executing a goroutine of 26 azcopy and I got azcopy stuck and didn't complete the copy.

@Abed Ewiwi Thanks for sharing the update.
Just for debugging, can you please share if- does azcopy works if you execute directly from CLI?
