Our Wandering Path to Supporting 1000s of Domain Names


A few weeks ago we announced that FusionAuth Cloud now supports unlimited custom domains. Here’s how we actually built it.

The ALB is responsible for handling the TLS handshake, the routing of traffic to customer deployments, as well as performing distributed denial of service (DDoS) protection and web application firewall (WAF) filtering. Is highly-available across multiple AWS Availability Zones(AZs) Is horizontally scalable and can handle load as we grow Can support dynamic management of TLS certificates without downtime Has no limits on the number of hostnames it can route All plans include a private instance (no shared public cloud) fully managed by FusionAuth, with options for backup, custom availability zones, uptime SLAs, and more to meet your infrastructure requirements.
