Prompt used
Broking platform deployment: customer web and mobile apps connect to API servers and a WebSocket market data service in AWS Mumbai. Orders go over a leased line to the order management system and risk engine in the exchange co-location data centre, which connect to NSE and BSE. Market data feeds flow back the same way. Back-office settlement and contract notes run in the cloud with PostgreSQL.
