笔记：Driving Architectural Simplicity - The Value, Challenge, and Practice of Simple Solutions

感觉这篇文章对于为什么，以及如何简化架构说的很透。

Key Takeaways
Simple architectures are easier to communicate, build, deploy, operate, and evolve. 
Architectural simplicity is not easily encapsulated by one type of model or practice. Several practices can be applied in combination to drive simplicity.
Agile practices stress simplicity. Architectural complexity can occur based on many factors such as design ability and focus, technology evolution, and organizational structure. 
Defining simple architectures is difficult and takes a concerted, continuous effort.

Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better. - Edsger W. Dijkstra (1984)

简化架构的好处（Benefits of Architectural Simplicity ）:
First, simple architectures are easier to communicate. Communication includes both documentation and comprehension. A simple architecture can be documented with a smaller model and fewer drawings/annotations which would lead to improved comprehension by stakeholders. Comprehension is critical for shared understanding, which some define as the architecture (from Martin’s Fowler’s seminal Who Needs an Architect?). A shared understanding is critical to maintaining alignment across teams and team members, and ensuring an efficient implementation.
Second, simple architectures are often easier to implement. They have fewer moving parts, fewer interactions, and fewer opportunities for failure. However, this isn’t always the case. Sometimes it may take more time to implement a simple architecture given the number of try/fail/learn iterations that go into the process of identifying a truly simple design.
Third, simple architectures are easier to deploy and operate. Fewer moving parts aligns to a more straightforward deployment. Then once in production, simple architectures are more easily scaled and monitored. Another great quote from Edsger Dijkstra is "Simplicity is a prerequisite for reliability."
Fourth, simple architectures are easier to modify and evolve. Simplicity is a key principle of Agile practices and a rule for XP development. Simple architectures allow the development team to be more productive since there is less complexity to track and fewer points of impact when making changes.
