How can we improve Azure Storage?

Enable multiple custom domains for storage accounts

I would like to register 2 or more custom domains to point to 1 storage account.

For example,, both point to

    One of the challenges this would help to address is uniform performance for all target users.

    As an example, certain CDNs may provide better bandwidth and/or response times for known regions for providers. Being able to simply use the better suited CDN in these scenarios would provide a superior user experience.

    This could also serve as an escape hatch should a caching mistake be made. Allowing a zero downtime fix for a problem that could otherwise prove extremely difficult to address.

    At present it's possible to only map a single CNAME record to blob storage. It would be useful to map multiple CNAME records.

    There is a work-around if you don't mind spending the extra money though: Create an Azure CDN for the storage and then map multiple CNAME records to the CDN instead.

    This is really important and needed feature.

    Just two Real World scenarios:

    1. HA - When I use CDN, I need more of one CNAME record pointed to the BLOB storage - if the First CDN no respond, fallback with Second/N one.

    2. Performance - The limit in browsers like Chrome, Firefox and IE is 6 concurrent downloads from the same domain/subdomain. 30 is the global max concurrent connections of most modern browsers, and this equals 5 hostnames times 6 connections per host. If I can point 5 CDN CNAME records to One BLOB storage I can get maximum download parallelism for my site.

    I encourage all users to vote for this multi-domains proposal, because this is important and cost Nothing to Azure to add it.

    I really hope someone from Azure Team read this and really implement it in production ASAP.

    That would be really a useful feature!

    It's also possible to have different domains pointing to a website deployment - why not also to storage accounts?
