copy files directly from from S3 to Azure blob

hi,

You can try Azure AzCopy tool to do this. Refer here for more details: https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-s3 So, you can do this for free. But note that that data transfer costs for moving the files from Amazon S3 will still apply. So, in that way it won't be a zero cost transfer. After configuring your Azure storage account and installing the AzCopy tool, here is a sample command that you can use to copy the files

azcopy copy "https://s3.amazonaws.com/{bucket}/{path}" "https://{storage-account}.blob.core.windows.net/{container}/{path}" --source-key "{aws-access-key}" --dest-key "{azure-storage-access-key}"

Hope this helps

Thanks Arun
