web architecture for dummies

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

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

First, website attack and defense Attack: 1. XSS attack: Dangerous character escapes, HttpOnly 2. 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

This article has been included in the "Large Web site Technology Architecture" Reading notes series directory stickers, click to access the directory for more content.One, scalable and extensible-silly division is not clearPrevious notes we learned about scalable architectures, but in real-world scenarios, including many architects, are often confused with scalability and extensibility, with extensible repr

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

.2.2 Obtain target web server informationWeb server information collection is the main content of Architecture Analysis. Currently, we only discuss the analysis from the http protocol perspective.Banner capture. The most direct way to capture Banner is to use the browser extension tool I introduced in the previous section. The following uses the FireFox extension Live HttpHeaders as an example. We start the

The second article of the grid site architecture case series. Mainly explain the website Architecture analysis, website architecture optimization, business split, application cluster architecture, multilevel cache, distributed session. Five, the website structure Analysis Based on the above estimates, there are several

This is the second article in the series of Web services architecture. Starting from the technical definition of Web services, we will discuss what Web services are. First, the author analyzes in detail the basic role of Web services as software components in the Internet en

components of the Web service.A little bit about the service transport layer the bottom of the Web service stack is the service Transport layer. This layer is responsible for the actual transmission of XML messages between the two computers.Hypertext Transfer Protocol (HTTP) HTTP is currently the most popular choice for service transfer. HTTP is simple, stable, and widely deployed. In addition, most firewa

thing. In the book, see the author wrote such a sentence, posted out with you are learning the rookie on the way to share: "In thefinal analysis, technology is for business services, technology selection and decision-making relies on business planning and even strategic planning, leaving the support and drive of business development, technology can not go far, even will be lost" . Out of an internship for more than a year, a lot of feelings about this sentence, but also eat a great deal of loss

allocation. Overall structure of the hybrid mode: Iii. Architecture of large-scale distributed Web Crawler: From these figures, we can see that distributed Web Crawler is a very complex system. Many factors need to be considered. Performance can be said to be an important indicator. Of course, hardware resources are also required. But it is not in th
