What we do
Four problems, and they are the expensive ones.
Not a general cloud practice. These are the four places where trading firms consistently overspend, under-measure, or fail an audit — and all four sit on the AWS side of the line.
Research & backtesting at scale
Ten thousand cores for a parameter sweep, then nothing until the next one. Spot fleets with checkpointing that survives interruption, and a cost model your COO can actually read. Spot pricing alone typically runs 60–90% below on-demand — the saving is arithmetic, not a promise.

Tick history that stays queryable
Years of market data in one schema, partitioned so a five-year query doesn't cost five figures. Point-in-time correct, deterministically replayable, and read by the same code path in research and in production.

Post-trade risk & surveillance
Trade reconstruction, order-lifecycle capture, clock-offset evidence for MiFID II RTS 25, and a retention policy that survives a regulator asking about a specific millisecond two years ago. Auditable, and boring on purpose.

The colo bridge
Direct Connect from your cage into AWS with redundant paths, BGP policy that fails the way you expect it to, and a hybrid topology that behaves the same at 09:30 as it did in testing. Including the DNS, which is usually what breaks.
