This session explores a real-world AWS OpenSearch case study, highlighting the technical and operational trade-offs between serverless and provisioned architectures. I will discuss the specific challenges we faced with Serverless and why it did not meet our requirements.

I am a Senior Software Engineer at Trainline, where I focus on architecting and scaling high-performance backend systems. My path to backend engineering was non-traditional; starting in Game Development and studying Physics, I developed a deep appreciation for performance, concurrency, and complex simulations.
