Thank you for your feedback. We are currently in public preview of static website hosting for Azure Storage to enable this scenario. Check out the blog post here for more details: https://azure.microsoft.com/en-us/blog/azure-storage-static-web-hosting-public-preview. The feature set includes support for default documents and custom error documents for HTTP status code 404.
For any further questions, or to discuss your specific scenario, send us an email at firstname.lastname@example.org.Christopher Zenzel commented
Google Drive supports default documents in shared folders via their sharing. I would use the Blob storage for development of client static sites and templates instead of Google if they allowed default documents.Christopher Zenzel supported this idea ·
