the operation. For example, when a user hovers over a drop-down menu, the corresponding option is displayed.Content Distribution Network (CDN). Typically, HTTP requests from the browser are filled in by a CDN or other caching technology, which avoids the performance discount that comes with the backend Web server at all times. This approach is designed to provide better performance for static content such as images. For example, Akamai (Network acces
distribution Network". Facebook uses content distribution networks (CDNs) to distribute static files like images, CSS tables, and JavaScript files. As a result, these files will be backed up in many CDN data centers around the world.Static content often represents the bandwidth size of the site and can be easily replicated through a CDN. A third-party CDN is usually used by the website. For example, Facebook's static files are hosted by Akamai, the l

Internet servers, and its services are not a browser, although the service is experienced by the user in the browser. Google's flagship product, the search service, does not even host the content it allows users to search for. Very much like a telephone call process, not only at both ends of the call, but also in the middle of the network. As an intermediary between users and their online experience, Google works in the space between browsers, search engines, and final content servers.

For start-ups and personal sites, it may not be possible to use CDN's cost budget, but as the target user base expands and becomes more globalized, CDN is required to achieve fast response. In the case of Yahoo, the static content of the website program they transferred to the CDN saved more than 20% of the end-user response time. Using CDN is a way to dramat

The realization method of Viacom
Although many organizations use ORM and traditional relational databases to solve this problem, Viacom uses a radically different approach.
In essence, they cannot afford to have direct access to the database at all. First, most of them deal with streaming data, preferring to use Akamai to distribute content geographically. Second, the complexity of the page may take tens of tho
download pages of pictures, style sheets, scripts, flash these components. This is the Golden Rule of website display . so instead of redesigning the structure of the site, it's better to implement the distribution of these static components first. This is not only a significant reduction in response time, but also a simple task because of the presence of content distributed networks (delivery networks).
Content Distributed Network (CDN) is a collection of servers distributed in different regi
the origin and destination of all the traffic information, but also real-time, and then give you a clear road, how magical, but these we in livenet have already been implemented.
Here's a look at the traditional content distribution network.

With the rapid development of the Internet, in today's Internet is a very fast platform, netizens want in the shortest possible time to find the information they want. According to the survey by Akamai, the world's largest CDN service provider, if a page is loaded for more than 4 seconds, 75% of visitors will exit directly. What is this warning to our webmaster? The answer is very simple, as a webmaster we need to optimize the loading time of the site
On Fedora9, the Fedora Project continues to maintain its most creative tradition as the main release version, integrating new applications with its own innovations.
