Overall Architecture Analysis of muduo library and muduo Architecture Analysis Muduo is a high-quality Reactor network library, which adopts one loop per thread + thread loop architecture. The code is concise and the logic is clear. It is a good model for learning network programming. Muduo code is divided into two parts: base, net, and base to implement some bas

Simple web layer-3 architecture system (3rd edition), web layer-3 Architecture Today is the third edition. As we did a few days ago, we still need to optimize the code. The three-tier architecture is an idea. Whether the overall system security and high performance can be ensured depends on whether the code is properly written, whether the logic is rigorous. Ye

In the previous article I talked about the front and back of the separation of some views, this view is from a macro point of view, no concrete landing to achieve, today I will continue the topic of the previous article, from the front-end of the architecture design point of view of the front-end separation of a specific implementation of the program and I originally conceived a great change, But the core idea has not changed, is the control layer bel

terms of architecture, my point is that since open source is used, don't be afraid to change the source code if you encounter any problems. We must not stay at the users of the framework. It is not so difficult to customize the framework or even contribute code to the author.

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really
