web architecture for dummies

based on data technology, with different users, different times, the return of different pages.The common dynamic page technology has ASP, PHP, JSP and so on.ASP (Active Server Pages) is a background scripting language developed by Microsoft, and his syntax is similar to that of visual Dasic, where background scripting code can be embedded in HTML pages. At the time of execution, ASP is the program engine with ISS call, explaining the execution of ASP code embedded in HTML, and finally sending

Sites are small sites step by step into a large web site, and this challenge is mainly from the huge user, the security environment is bad, high concurrent access and massive data, any simple business processing, once need to deal with the number of P-meter data and face hundreds of millions of users, the problem will become trickyLet's talk about the evolution of this process:Initial stageLarge Web sites a

phase, but also can start to use a large number of inexpensive machines to support the huge amount of traffic and data, combined with this architecture and the experience of so many evolutionary processes to adopt a variety of other methods to support the increasing volume of traffic.Look at the diagram of the system after the completion of this step:This step involves these knowledge systems:This step involves a lot of knowledge system, requires a d

The value of the evolution of large web site architecturesthe value of the site is that it can provide users with what value, is what the site can do, but not how it is done, so in the site is still very small to pursue the structure of the site is trifles, outweigh the benefits. Small sites need to do is to provide users with good services to create value, to get the user's recognition, live, savage growth. Website

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 representation of scalability. So here, follow the author we have to clarify these two concepts, to avoid the future we will not be confused about it.( 1 ) Extensibility ( extensibiltiy )　　refers to the ability of the system function to be continuously expanded

Dynamic application, relative to the static content of the website, refers to the Web application software developed in the server-side language such as C + +, PHP, Java, Perl,. NET, etc., such as forums, web albums, friends, blogs and other common applications. The dynamic application system is usually inseparable from the database system, the cache system and the distributed storage System. The large-sca

kinds of users are distributed next to each other. 　　2, page and behavior The page and behavior are represented by a user + verb + a page noun. Like what: Creation begins 　　1, create a single role of the business flow chart Draw the "shopper" flowchart first. 　　　　2, and then draw the other role of the flow chartContinue to draw the business process of "people who buy gifts." If the Web site adds a "buy gift" requirement, add a "My

capabilities required for large systemsAs a large-scale web system, it has the ability of large-scale system, can be more advantageous in business logic to deal with a variety of "big" (large amount of data, large concurrency, complex system logic, demand development iterative fast) problem. So what is the ability of such a system?The processing power, that is, from a non-technical level embodies a system performance problem. As the boss tells you, th

Web LayerThe principal architecture can be based on Struts 1.x/2.x, of course there are many better control layer frameworks to choose from, with fast agile as the guideline. Abstract the operation of the core Library encapsulation controller and middle tier. In a large-scale cluster environment, session replication can cause serious performance problems. Consider using cluster caching + cookie validation i
