Azure Front Door Service (AFD), the new Azure capability providing fast and secure entry points to your web applications hosted on Azure, which was in preview for about a year, is now generally available.
AFD includes SSL offloading, URL redirect and rewrite, HTTP/2, IPv6 or session affinity.
You can start using/evaluating it thanks to this sample guide https://docs.microsoft.com/en-us/azure/frontdoor/
In addition of AFD going GA, you can also start evaluating Web Application Firewall (WAF) for AFD in preview.
Web Application Firewall is providing centralized protection solution for your web application – for those who knew ForeFront TMG, this is the same type of solution.
You can start looking at WAF for AFD thanks to this documentation https://docs.microsoft.com/en-us/azure/frontdoor/waf-overview
