amount of money, to solve the unrecoverable failure is basically unlikely.We first try to solve our failures from an architectural approach, which is similar to a design pattern and is called an architectural pattern.For single-machine unavailability, there is a professional term called single point of failure, the best way is to deploy multiple machines, through multi-machine load balancing, to avoid single point of failure. Distributed Load Balancing For multi-machine unavai

Translated by Peter Seibel/Hao peiqiang This article is an interview with Joshua Bloch, Chief Java architect of Google, by Peter Seibel, expert of commmon lisp, talking about what books programmers should read, how they can quickly get familiar with a new language, and why they choose programming languages is like choosing a bar. 　　 　　Seibel: How did you start programming? Bloch: I think this is because of my family influence. My father is a chemist

This afternoon, I made a brain chart. For ease of display, I cut it into four parts and described my basic understanding of the architect's ability. These four figures do not necessarily cover all the capabilities of the architect. However, I try to provide scope and useful suggestions, hoping to inspire and benefit everyone. Figure 1: Basic perspective of this capability model. Compared with Ericsson's human model, please note that it does not in

1. IntroductionComputer science is an application science, and its knowledge system is a typical inverted triangle structure. It does not use much basic knowledge. It only produces many branches with different application fields and directions, therefore, programming is not a very difficult task. A high school student can do it after specific training. However, programming and programming are two different things. Some programmers have become architects several years later, while others are stil

Cainiao to be an architect (II) -- java Performance Optimization-for loop and java Performance Optimization When the same function is completed and implemented using different codes, the performance may be significantly different. Therefore, for some performance-sensitive modules, it is necessary to optimize the code. Today I will talk about java code optimization. Today I will talk about optimization for the for (while and so on) loop. As a loop of

The latest version of Microsoft. NET,. NET Framework 3.0, opens new possibilities for developing the next-generation business solution software system. It is designed to improve productivity, reduce infrastructure complexity, and provide a consistent metadata system, making it easier to develop enterprise-level services, workflow solutions, and user experience software systems. During my discussions with a large number of architects, I have heard that solution architects are very concerned about
