The Micro-service Architecture Design Research of Financial Trading System based on Domain Engineering

Abstract

The purpose of this article is to propose a domain engineering-based micro-service reference architecture for financial trading platform, which can solve the problems of high complexity and high maintenance cost of a real large-scale financial trading system and try to provide a general solution for similar scenarios in the future. Starting from the concept of domain engineering and micro-service and the relationship between them, this article briefly introduces the background and pain points of the actual large-scale financial transaction system, emphatically expounds the principles and methods of domain analysis and micro-service disassembly for the legacy system, and puts forward a reference architecture with future reuse significance. The corresponding suggestions are also given for how the new micro-services will coexist with the existing legacy systems for a long time. In order to promote the landing of domain engineering and micro-service, besides theoretical research and necessary practice, enterprises also need to change the traditional management mode and introduce DevOps and other mechanisms, so that business processes and technologies can support the rapid development of business.

An Experimental Study on Microservices based Edge Computing Platforms

“…Fine granularity means that there is a bare minimum of centralized management of these services. Moreover, there are instances where the service is not micro [26]. Loose coupling implies that each of microservices components has few dependencies on other separate components, which makes the deployment and development of Microservices more independent [23].…”

Decentralized Smart Surveillance through Microservices Platform

“…Moreover, there are instances where the service is not micro. 18 In the smart safety system, some parts of the code is inseparable which makes a bigger service. Microservices will become as big as it needs to be to provide coherent, reliable, and efficient functionality.…”
