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 issues: the need to deploy a large number of servers, peak computing, and possibly 30 Web servers to deploy. And these 30 servers, onl

The previous article introduced the server security aspect in detail, next continues to introduce the Linux server file backup, the database backup, the data security storage related electronic commerce system architecture. There are a variety of solutions for security, where data backup is the top priority. E-commerce sites pay more attention to data security, data backup scenarios, including local backup

response time of the web system is, and the system is stuck in an exception.4. Optimistic Locking ideasAt this time, we can discuss the idea of "optimistic lock". Optimistic lock, is relative to the "pessimistic lock" with a more relaxed locking mechanism, mostly with version number (versions) update. The implementation is that this data all requests are eligible to modify, but will get a version number of the data, only the version number of the mat

snapping failed. In this case, we don't need to think about the queue, but it will increase the CPU's computational overhead. However, in general, this is a better solution.There are many software and services that are supported by the "optimistic lock" feature, such as Watch in Redis, which is one of them. Through this implementation, we guarantee the security of the data.Iv. SummaryThe internet is developing at a high speed, and the more users who use the Internet service, the more high-concu

influence far more than traditional jewelers. But in China, online jewellery retailing is much more backward than any other industry-type web site. Many of the domestic online jewelry shopping mall, seems to always appear tepid. In 2007, however, all this was a turnaround. Today, retailers in the online jewellery market can be said to have caught up with a big increase in revenue in the golden Age. IDC organizations insist that the network jewelry ma

) cache trigger expires;6.4 Single Sign-on (distributed session)The system is divided into several subsystems, and after being deployed independently, it will inevitably encounter the problem of Session management. Can use session synchronization, Cookies, distributed session mode. E-commerce websites generally use distributed session implementation.Further, we can build a perfect single sign-on or account management system according to the distribute

brute. this de-duplicated queue implementation can be implemented with existing modules, such as a Python queue module, inheriting the classes in this module and writing down several methods to implement such a deduplication queue. You can also use an existing queue system, or even use a database directly to implement a queue. The advantage of using a database is that when the entire system is down, the messages in the queue are still there after the system restarts, and the caches of those pag

Although this approach creates a degree of personalized product, they have nothing to do with the Web experience. user Interface : Many sites allow users to customize personalized interfaces or skins, such as MySpace's background (perhaps Twitter is more relevant?). Or as a Facebook profile page, you can add/remove applications. Personalized UI rarely appears on E-
