Legacy systems don’t have to hold you back. In high-volume markets where milliseconds matter, MarketAxess—an electronic trading platform for institutional investors—needed a way to scale trade data reliably across on-prem systems and the cloud. That journey—from self-managed Apache Kafka® to MSK to Confluent Cloud—reshaped how their engineering teams build, scale, and govern real-time infrastructure.In this episode, Andy Steinmann, Software Engineering Manager at MarketAxess, breaks down how his team evolved from a monolithic, socket-driven architecture to a streaming-first platform. He shares why Kafka became the foundation of their 2.0 strategy, how Confluent Cloud eliminated operational drag during peak trading windows, and what it takes to modernize without disrupting a mission-critical financial ecosystem. You’ll learn:How MarketAxess scaled real-time trade flows across on-prem and the cloudHow Confluent Cloud eliminated outages and operational bottlenecksHow to approach modernization through iterative “2.0” patterns and dark deploymentsIf you’re ready to explore hybrid connectivity, governance, performance tuning, and the operational realities of scaling market-data workloads, this is the episode for you.About the Guest:Andy Steinmann, Software Engineering Manager at MarketAxess, is a seasoned software engineer with 20+ years of experience in web, mobile, and backend technologies delivering proven solutions to thousands of users.
