Alex Seaton from Man Group presented at QCon London 2025 on transitioning from a high-maintenance MongoDB server farm to a serverless database solution using object storage for hedge fund trading applications. He emphasized the advantages of serverless architecture, including improved storage management and concurrency models, while also addressing challenges like clock drift and the complexities of Conflict-Free Replicated Data Types (CRDTs). Key takeaways highlighted the need for careful management of global state and the subtleties involved in using CRDTs and distributed locking mechanisms.
