Some time you want to spin up a simple, static web hosting somewhere, just HTML, JavaScript the most. If you don’t bother to create a new WordPress site or set up a Windows Server with IIS etc in Azure. Now there is a solution.
Azure treats this as a serverless service, site content are hosted in Azure Storage account, and that is enough to get a new website running. The service itself is free as preview now, but storage account itself still has a cost.
Here is announcement blog: https://azure.microsoft.com/en-au/blog/azure-storage-static-web-hosting-public-preview/
Here is the main MS Doc: https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-static-website
You may already knew, how to create a storage account: https://docs.microsoft.com/en-us/azure/storage/common/storage-quickstart-create-account?tabs=portal
Very handy tool, still in beta I guess: https://azure.microsoft.com/en-us/features/storage-explorer/, you can use it to directly access Azure storage contents.
You will have a URL like: https://storageaccountname.zone.web.core.windows.net/index.html, the HTML file will be in the $web container.
Of course, you will be able to use your own domain name for the site.
