Unitized architecture is an architectural design that divides a large application system into several independent functional units (modules). Each functional unit is responsible for specific business functions and can be independently developed, deployed, and run. The following are the main contents and key points of modular architecture design: Split business functions: Split large application systems into multiple functional units based on business functions. Each functional unit focuses on specific business areas to avoid overly complex and bulky individual applications. Loose coupling and independent deployment: Each functional unit should be Loose coupling and run independently of other units. This can improve the maintainability and scalability of the system, and reduce dependencies between units. API and interface design: Define clear APIs and interfaces for functional units, enabling them to interact with other units. A good interface design can improve communication efficiency and reliability between units. Unified data access: Provide a unified data access interface for all functional units to avoid duplicate data storage and query operations. This can improve data consistency and reliability. Robust monitoring and logging: Add robust monitoring and logging functions to each functional unit for easy troubleshooting and performance optimization. Automation and continuous integration: Through automation and continuous integration tools, automatic construction, deployment, and testing of functional units are achieved. This can improve development efficiency and Software quality. Elasticity and scalability: When designing functional units, the system's elasticity and scalability are taken into account, enabling the system to automatically scale and adjust according to load and demand. Security: Provide appropriate security protection for each functional unit, including identity authentication, authorization, and data protection. In the design of modular architecture, it is necessary to comprehensively consider business requirements, technical requirements, and team capabilities. A good modular architecture design can improve the maintainability, scalability, and reliability of the system, adapting to constantly changing business needs and technological developments.
