For more information on static websites you can refer to the documentation here. Azure Storage does not yet natively support HTTPS with custom domains; so you will have to use Azure CDN if that is a requirement. There's no way to configure headers as part of the static website feature. However, you can use Azure CDN to add headers and append (or overwrite) header values. CORS is not support for static websites. The website should be able to scale based on the performance of the storage account.
Hope this helps! Let us know if you have further questions or concerns and we will be happy to help.
