Azure Front Door has been around for some time now and even the new evolved version has been with us for a prolonged period of time but still it is in preview.

Who is it for?
Azure Front Door is one form of load balancer with extra features. During on-premises work I used similar features with external Load balancers and IIS Url rewrite modules to accomplish the same kind of configs.
Then came Windows Application Proxy, what a joy.
So for us who did this and who want to do it still but in the cloud.
Key features included with Front Door:
- Accelerated application performance by using split TCP-based anycast protocol.
- Intelligent health probe monitoring for backend resources.
- URL-path based routing for requests.
- Enables hosting of multiple websites for efficient application infrastructure.
- Cookie-based session affinity.
- SSL offloading and certificate management.
- Define your own custom domain.
- Application security with integrated Web Application Firewall (WAF).
- Redirect HTTP traffic to HTTPS with URL redirect.
- Custom forwarding path with URL rewrite.
- Native support of end-to-end IPv6 connectivity and HTTP/2 protocol.
You could example use this feature to deploy a custom domain login from Azure B2C solution or any other solution that you want to provide secure and access to. It could be even your on-premises or what ever web-based service.

How to?
Search for Front Door or just a create a new resource and you will be welcomed with the following options.
If you go with quick create it will allow you to configure the whole deployment with a Front Door designer.
Frontend pool is the name of your instance, backend pool is the backend service what you want balance to.
If you want to use a custom domain, you will add it to frontend pool and you have to add an cname that points to your adf domain, like so.
Go to public dns and add it.
Once done go back to your AFD instance.
Then select “Add” and voila.
The next thing is to add the custom domain to your routing rule. Open and expand frontends / domains and select custom domain.
Once done and saved the config, you will open the custom domain.
Now you will enable the HTTPS and certificate request is pushed forward, it will take time, just have patience.
Wuhuu, now you have your own custom domain and MS generated certificate. That was easy.
From here you can see what Load balancer would be right for your.
