ServiceComb-based Microservice Practice of MedSci Miao Yanjie Chief Architect, MedSci Service Mesh-based Microservices and Those Based on a Traditional Architecture Two network platforms, covering all users in improving report processing efficiency by more than 80% by using new technologies such as microservices and AI. iDrugSafety Competitiveness Analysis Quality Cost Specifications System Functions evolved. • Multiple languages are supported. The hybrid deployment of Service Mesh-based microservices and those bases on a traditional architecture is supported. • There are many successful commercial

system configurations through easy-to-understand data and portals. Develops and deploys microservices in the same domain using multiple programming languages. Enables collaboration and governance quickly build microservice projects based on popular microservices frameworks and popular programming models, reducing the cost of microservices entry, enabling users to focus on business development 验收微服务 Collaboratively implement standard management of contract-based data and services Divide microservices (including dependencies) Define contract (interface and model) Release contract Microservice

Meetup 联合发起⼈人 关于我 议题 • 微服务架构的核⼼心 • 微服务架构设计原则 • 微服务架构⽣生态系统 Are you using microservices? Are you using microservices? https://www.nginx.com/resources/library/app-dev-survey/ 什什么是微服务架构？ • 微服务架构 等 Microservices – the new architectural style. Martin Fowler,Mar 2014 ...... Micro (u)Services Architecture - small, short lived services rather than SOA. Fred George 2012/3 Microservices are

bounded contexts in our domain, and our microservices represent those bounded contexts, we are off to an excellent start in ensuring that our microservices are loosely coupled and strongly cohesive
