Anjuke Android project Architecture Evolution and android Architecture Evolution
After three years of employment as an anjuke, the engineer and Team Leader witnessed the development of the Android Team. Therefore, sharing these records is a summary of some of your work over the past three years. I hope to help you and give you valuable suggestions.I. Merger of the three networks
Three years ago, when I join

Large-scale website Architecture Evolution (8) Business splitting and Architecture Evolution
In order to cope with increasingly complex business needs, large websites divide their businesses into different product lines and assign them to different development teams. This facilitates application expansion and maintenance. At the same time, different applications correspond to different databases, which red
Evolution of large-scale website architectures (9) servitization and website Architecture Evolution
As the business is smaller and smaller, and each application is independently deployed and maintained, such architecture has the following problems:
1. The number of database connections. If each application is connected to an existing database, the number of database connections exceeds the limit when the
Architecture Evolution-Initial Knowledge and initial knowledge of Architecture Evolution
Here are some of your own understandings. If you have any misunderstandings, thank you very much.
1. At the initial stage of website construction, users and access volume were very small, and application services + database + file services were all in one server.
2. Users and access traffic increase, application server
Evolution of large website architectures (3) Use cache to improve website performance and Architecture Evolution
Website access also follows the 80% law: 20% of business access is concentrated on 20% of the data. If we cache of the data, can we reduce the access pressure on the database? During project development, we usually cache some basic information, such as country, city, airline, airport and termina
Evolution of large website architectures (2) Separation of databases and application servers and Architecture Evolution
As the number of users and concurrency increases, a single server has a performance problem. In this case, the application and database must be separated. After the separation, the entire website becomes three servers: application Server (or web Server), database server, and file server.

Coupled with the recent feeling that many students are difficult to understand why a Web site requires so complex technology, so with the idea of writing this article, in this article will explain a common web site to develop into a large web site in the process of a more typical structure evolution and the knowledge system needed to master, Hope to be engaged in the Internet industry students a little preliminary concept,:), the text of the wrong pla

At first, because of some ideas, so on the internet to build a website, this time may even host is rented, but because this article we only focus on the evolution of the architecture, so it is assumed that this time is already hosting a host, and a certain amount of bandwidth. This time because the site h

In hostswap dcevm, we have a simple understanding of dynamic code evolution VM.ArticleThe implementation principle of dynamic code evolution VM is introduced.
There are two concepts that need to be different:
Dynamic code evolution (hereinafter referred to as DCE): generally refers to Java modification at runtimeProgramSuch as AOP.
Differential Evolution (differential evolution,de) is an evolutionary algorithm based on group difference, which is proposed by Rainer Storn and Kenneth Price in 1996 to solve Chebyshev polynomial. The differential evolution algorithm is superior in the first IEEE Evolution calculation competition, and has been widely
switching, which is adopted on many large Web sites including search engines, which have low cost, high performance and strong extensibility, and it is easy to add or subtract nodes to the architecture at any time. Such a structure I am ready to empty a special detail and discuss with you.For large web sites, each of the previously mentioned methods may be used at the same time, I introduced here is relatively simple, the implementation of a lot of details of the process needs to be familiar wi
Large-scale website architecture evolution and Knowledge systemThere have been some articles about the evolution of large-scale web sites, such as LiveJournal and ebay, which are well worth referring to, but feel that they are talking more about the results of each evolution than on why they need to be evolved, Coupled with the recent feeling that a lot of studen
I have also introduced the evolution of large website architectures.ArticleFor example, livejournal and eBay are all worthy of reference. However, they feel more about the results of each evolution, without a detailed explanation of why such an evolution is required, coupled with the recent feeling that many students are hard to understand why a website requires

Take advantage of the holiday, finally the "large Web site technology architecture Core Principles and Case Analysis" this book read. This book gave me a new understanding of the site architecture, the whole book is more simple and easy to understand, so that people who get started more easily understood. It introduces a lot of technical concepts. To reverse proxy and CDN and so on. I write two articles, is the summary after reading.
