web architecture books

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

The last section of the "large-scale Web site Architecture Evolution", today to talk about the structure of the model, what is the model? Each pattern describes the core of a problem and problem solution that repeats itself around us, so that you can reuse the program over and over again without having to do repetitive work, and the key to visible mode is repeatability.The goal of the

Currently, cache is widely used in website architecture to provide the performance of Web applications. The following types of cache architectures exist for different websites. (1) Single-host Cache (2) Simple distributed cache (3) cache cluster Using Replication (4) cache cluster using hash (5) high-performance, high-reliability cache Cluster The following is a detailed analysis of the applicability and ad

The next few blog posts, bring you a simpler macro-architecture and detailed implementation of the deployment of the tutorial, no figure no JB----> The above cluster environment is briefly described as follows (2 represents the number of services or software, i.e. there are multiple identical services): 1, Nginx reverse proxy server (NGINX2, Keepalived2, yum source 1): The user all requests through the Nginx reverse proxy to distribute, and reali

the same result, that is, the service is idempotent. Service idempotent is sometimes natural, such as setting the user's gender as a male, regardless of how many times it is set, the result is the same, but for operations such as transfer transactions, the problem becomes complex and requires information such as transaction numbers. For service invocation validation, only valid actions can continue. Study Note 6: The core Principles and case studies of large

sick half a day.Let's see how many places we need to change.1. Database2, Pojo3, DAO's configuration file4, interfaceYou may also want to modify the action and other places. And the configuration file is prone to bugs ...Anyway, I'm fed up with the days like this ...Two-tier streamlined architectureLater, after entering Hunan province, after the company framework, I reformed a 2-tier architecture using SPRINGMVC and Oracle stored procedures to implem

optimization StrategyAccording to the website layered architecture, can be divided into web front-end performance optimization, Application server performance optimization, Storage server performance optimization.2.1 Web front-end Optimization 2.1.1 Browser access optimization Reduce the number of HTTP requests, mainly by merging Css,javascript, picture

: This article mainly introduces the first chapter: the overall architecture of the high-performance Web macro architecture. if you are interested in the PHP Tutorial, refer to it. The following blog posts will provide you with a relatively simple macro-architecture solution and detailed implementation and deployment t

Java from junior programmer to architect video, document, architecture design, large Web site architecture analysis, big Data analysis data, build high concurrency, high-powered architecture design materials need to contact me.

1. First stage: Single Server architectureThis stage is our initial stage, for example, when we started a business, we just bought a cloud host.At this stage, in order to save costs, we put all the applications, databases, files on this server.Then, the cost of CPU or memory is also used in the development phase to take the least acceptable cost, and then start our server development path.2. Phase II: Separation of application services and data ServicesWith the first launch of the site, if our s

In the process of expanding the size of Web websites from small to large, the database access pressure is constantly increasing, and the database architecture needs to be dynamically expanded, the database expansion process consists of the following steps. Each extension can improve the performance of the deployment method in the previous step by an order of magnitude. 1.

After reading there is a book, should have a harvest, have a summary, recently the "large Web site Technology architecture" a book to read, give the impression is profound, coupled with the book on the reverse proxy and load balancing and session independent storage and caching, so the book seems to be quite easy to understand, And the author Hae gives the impression (book) is also quite profound, I have le

-installation of RABBITMQ3) "ZeroMQ"Known as the fastest message queue, it is actually similar to the socket of a series of interfaces, the difference between him and the socket is: the ordinary socket is end-to-end (1:1 of the relationship), and ZMQ is can be n:m relationship, people on the BSD socket understanding more is the point-to-point connection, A point-to-point connection requires an explicit connection, a destroy connection, a selection protocol (TCP/UDP), and a processing error, and

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 prox

Injection attack: Parameter binding 3, CSRF (cross-site request forgery): Token, verification code, Referer Check 4. Other vulnerability attacks Error Code HTML annotations File Upload Path traversal Defense: 1. Web Application firewall: modsecurity 2. Website security vulnerability Scan

First, performance-response time determines the user(1) Browser side:① browser cache;② using page compression; Ps:gzip compression efficiency is very high, usually can reach the 70% compression ratio, that is, if your Web page has 30K, after compression becomes about 9K. To enable gzip compression to improve browsing speed, you can browse this article: http://www.chinaz.com/web/2012/1017/278682.sht

exceptions?). Cost: Cost is an important factor. It is clear that this includes hardware and software costs, but it is also important to consider other aspects of the cost of deploying and maintaining the system. The amount of time developers build systems, operations deployment time, and even training time need to be considered, cost is the total cost. Each of these principles provides a fundamental decision for designing a distributed Web
