Generally available: Azure Gateway Load Balancer

Gateway Load Balancer is a fully managed service enabling you to deploy, scale, and enhance the availability of third party network virtual appliances (NVAs) in Azure. You can add your favorite third-party appliance whether it is a firewall, inline DDoS appliance, deep packet inspection system, or even your own custom appliance into the network path transparently – all with a single click. With Gateway Load Balancer, you can easily add or remove advanced network functionality without additional management overhead. It provides bump-in-the-wire technology that ensures all traffic heading to a public endpoint is sent to an appliance before it reaches an application. Gateway Load Balancer supports flow symmetry and source IP preservation. As a result, packets traverse the same network path in both directions, enabling stateful appliances, and your traffic remains transparent to both your appliances and your application. Gateway Load Balancer is now generally available in all public regions, Azure China cloud regions, and Azure Government cloud regions.
