Question
You develop an app that allows users to upload photos and videos to Azure storage. The app uses a storage REST API call to upload the media to a blob storage account named Account1. You have blob storage containers named Container1 and Container2. Uploading of videos occurs on an irregular basis. You need to copy specific blobs from Container1 to Container2 when a new video is uploaded. What should you do?
Options
- ACopy blobs to Container2 by using the Put Blob operation of the Blob Service REST API
- BCreate an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet
- CUse AzCopy with the Snapshot switch to copy blobs to Container2
- DDownload the blob to a virtual machine and then upload the blob to Container2
Explanation
Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow. Asynchronous file uploads are a great fit for events. When changes are infrequent, but your scenario requires immediate responsiveness, event-based architecture can be especially efficient. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview
