Wildcard domains simplify the configuration of DNS records and Azure Front Door traffic routing configuration when you use a shared stem domain and tenant-specific subdomains. For example, suppose your tenants access their applications by using subdomains like tenant1.app.contoso.com and tenant2.app.contoso.com. You can configure a wildcard domain, *.app.contoso.com, instead of configuring each tenant-specific domain individually. ([View Highlight] (https://read.readwise.io/read/01h4fw00jbevcbn9b8mvwnm09n))

Wildcard domains work well if you send all your traffic to a single origin group. But if you have separate stamps of your solution, a single-level wildcard domain isn't sufficient. You either need to use multi-level stem domains or supply extra configuration by, for example, overriding the routes to use for each tenant's subdomain. For more information, see Considerations when using domain names in a multitenant solution. ([View Highlight] (https://read.readwise.io/read/01h4fw0hzqbkxzkg0ddwmvwve0))

Azure Front Door doesn't issue managed TLS certificates for wildcard domains, so you need to purchase and supply your own certificate. ([View Highlight] (https://read.readwise.io/read/01h4fw0m0ycf65bnsxbcx08r5h))
