APP架构一般性分类

参照：Architecture styles - Azure Application Architecture Guide | Microsoft Learn

应用APP架构通常分为

• N-tier
• Web-Queue-Worker
• Micrososervices
• Event-driven architecture 
• Big Data, Big Compute

具体的topology结构，可以看网页的不同图实例。

优缺点如下
 

Architecture style	Dependency management	Domain type
N-tier	Horizontal tiers divided by subnet	Traditional business domain. Frequency of updates is low.
Web-queue-worker	Front and backend jobs, decoupled by async messaging.	Relatively simple domain with some resource intensive tasks.
Microservices	Vertically (functionally) decomposed services that call each other through APIs.	Complicated domain. Frequent updates.
Event-driven architecture	Producer/consumer. Independent view per sub-system.	IoT and real-time systems.
Big data	Divide a huge dataset into small chunks. Parallel processing on local datasets.	Batch and real-time data analysis. Predictive analysis using ML.
Big compute	Data allocation to thousands of cores.	Compute intensive domains such as simulation.
