Alex Seaton from Man Group presented at QCon London 2025 about shifting from a complicated MongoDB server farm to serverless object storage for hedge fund applications. The original setup used Python and Pandas with a versioned MongoDB cluster, but its complexity became cumbersome. Seaton proposed a solution through serverless architecture, prioritizing ease of management, scalability, and speed. He defined serverless databases as software libraries and object storage, specifically using ArcticDB, which connects to object storage for executing queries, thus streamlining data handling in financial trading systems.
A main takeaway from the presentation is the effectiveness of moving from a complex MongoDB cluster to a simpler serverless object storage architecture.
