Summary of STOCK EXCHANGE SYSTEM DESIGN | AMAZON INTERVIEW QUESTION DESIGN STOCK EXCHANGE

00:00:00 - 00:30:00

The video discusses the design of a stock exchange system, focusing on the matching engine and the need for two matching engines per stock. It also discusses the different data structures that can be used to match orders and the role of the stream processing engine in the system.

• 00:00:00 The video discusses the design of a stock exchange system, with particular focus on the matching engine. The system should be able to add orders, cancel orders, and split orders, while being efficient and reliable.
• 00:05:00 The video discusses how the stock exchange system works, and how buyers and sellers can be matched. It also discusses the different data structures that can be used to match orders.
• 00:10:00 The stock exchange system design is explained in detail, with emphasis on how the high-frequency trading (HFT) clients interact with the system. The main points of the system are highlighted, including the use of an API gateway to route all requests to the correct services.
• 00:15:00 The video discusses the design of a stock exchange system, specifically focusing on the risk management system. The system is designed to allow for the processing of orders in a fast and efficient manner, while ensuring that all orders are safe to process. The system is based on a number of queues, each of which is handled by a separate virtual machine. Orders are matched based on a simple algorithm, running entirely in memory.
• 00:20:00 The video discusses the design of a stock exchange system, focusing on the need for two matching engines per stock, deployed in different machines and data centers.
• 00:25:00 The stock exchange system design includes a passive matching agent and an active matching engine in order to keep the system performing the same tasks. The primary data server stores the stock prices and information about orders and trades, while the UI and front-end application render graphs and charts. The stream processing engine is used to perform various other tasks, such as fraud detection and machine learning.
• 00:30:00 The stock exchange system design discussed in this video employs a passive and an active matching engine in order to ensure reliable communication between the different components of the system. The primary data server is also responsible for signing the data to be broadcast to the pop servers.
