Streaming financial market data through WebSockets

This talk will take you on a journey through the pursuit of performance in AWS serverless services. For those who have embarked on a similar path, you’d agree that it’s rarely a smooth ride. Complexities often arise, especially when navigating the mysteries of AWS (serverless) black boxes.

We’ll dive into XM’s backend architecture, which powers the real-time delivery of hundreds of thousands of financial market data to thousands of clients.

Along the way, we’ll uncover pitfalls that only emerge at scale, walk through our custom performance-testing suites that guide critical decisions, and examine challenges such as AWS quirks and scaling issues in Kubernetes for Java-based applications.

Ultimately, this session is about tackling the intricate scaling challenges that all backend engineers encounter and sharing actionable strategies and mindsets to overcome them.
