SOA and microservice examples

Monomer architecture

All businesses are in one application , such as

goods , Order , stock , user , Customer relationship , Statistical analysis , logistics , after-sales

shortcoming ： High module coupling , If you want to upgrade user management , All modules need to be packaged and deployed

Distributed architecture

Split into multiple subsystems according to business , After the split, the architecture evolved into

Trading subsystem   （ Including goods , Order , stock ..）

Personnel management subsystem   （ Include users , Customer relationship , Statistical analysis ）

Logistics after-sales subsystem      （ Including logistics , user , after-sales , goods ）

shortcoming ： There are repeated modules in different subsystems , Data synchronization is required

SOA framework

Extract repeated modules based on distributed architecture , Form reusable services , Evolved into

Trading subsystem   （ Including goods , Order , stock ..）

Personnel management subsystem   （ Include customer relationships , Statistical analysis ）

Logistics after-sales subsystem      （ Including logistics , after-sales ..）

Customer service , Goods and services

shortcoming ： The extraction boundary is not easy to determine , Such as the 3 Subsystem common services will be extracted , If 2 Whether the subsystem is public or not

Microservice architecture

Deploy independently in the dimension of service , One service, one application , Cluster deployment of each service , Evolved into

Goods and services , Order service , Inventory service , Customer service , Customer relationship services , Statistical analysis service , Logistics services , After-sales service

Trading subsystem   , Personnel management subsystem   , Logistics after-sales subsystem     Arrange the above services to quickly realize the business .

shortcoming ：1. Numerous services , Development is complex 2. Distributed data consistency is difficult to guarantee
