The Quant Systems Design Map

Quant engineering is not only writing fast C++. It is the discipline of putting mathematical models behind interfaces that survive traffic, retries, failures, audits, and changing market data.

A useful first map has five layers:

edge and traffic control,
application services,
hot state and asynchronous work,
data stores and event history,
observability and operations.

For a learning platform, the flow might be:

\text{browser} \rightarrow \text{CDN} \rightarrow \text{load balancer} \rightarrow \text{Next.js API} \rightarrow \text{Supabase}

For a trading platform, the shape is similar but the consequences are harsher:

Q1. What is the production boundary in quant engineering?

Problems

Type the five architecture layers in order: edge, app, hot-state, durable-store, observability.
