This is a talk I gave in May 2018 at KubeCon Copenhagen:
Form3 delivers cloud-based connectivity, payment processing, clearing and settlement services to a wide range of regulated financial institutions. Every transaction in fintech represents real money from real people. Protecting the integrity of service communication here is key. In this talk, I describe how Form3 built a payments platform that is reliable, safe, and resilient. I start by looking at a previous generation system that suffered from unreliable messaging and poor tail latencies. I then cover modern design techniques used to solve those legacy problems. This talk examines how Linkerd is used and deployed to protect financial transactions from failure and latency. Warning this talk contains live demonstrations!
