Processing Millions of Payments Through a Cloud-native Infrastructure with HAProxy

Processing real-time payments requires reliable and secure infrastructure, and as the daily volume at Form3 is expressed in millions, the stakes are extraordinarily high. At this scale, with customers relying on you for one of the most critical parts of their business, the technologies chosen have to be best-in-class. In this talk, we will share key decisions and how we found HAProxy to be the best match for both the project and Form3's cloud-native ethos. You will learn how HAProxy fits with the plethora of supporting technologies, how we configure HAProxy remotely using its Data Plane API, how we route traffic into our Kubernetes-based Faster Payments gateway, and how we implemented high availability with Keepalived and BGP. Join us as we relive our journey in building a next-generation payment processing platform for some of the UK's biggest banks.
