the file, It is considered that the file does not exist, and if the file can be found in bloom filters, the index system is requested. In this scenario, because of the element deletion operation, Bloom filters cannot use a bit array, and each bit needs to be replaced with a numeric variable that is incremented when multiple files share one.2) Content filtering: Akamai counts the number of Web file accesses in a server cluster two days, as you can see

With such a large-scale computer system, ultra-large-scale computing power, ultra-large-scale storage system, can do a lot of things. Notice that Gmail's space has been increasing. This proves that Goolge's ability to manage massive amounts of memory is increasing (just to keep up the stack of PCs:)). There is such a large-scale distributed system, nodes distributed throughout the country, the

use a Content distribution network (CDN), a large "proxy" server distributed system that is deployed in multiple datacenters. A proxy server is just an intermediary server that acts as a client and server.Companies that have a large amount of decentralized traffic can choose paid CDN companies to distribute their content to end users. Akamai, for example, is a CDN company with tens of thousands of servers deployed strategically geographically around

foreground Performance" section. Therefore, it is entirely possible to avoid the challenge of redesigning the application architecture and focus on decentralized static content. While this does not result in significant time savings, it is easy to implement with the help of content distribution networks. The so-called Content distribution network (Delivery NETWORD,CDN) is a collection of Web servers in which servers are distributed in different locations to distribute content more efficiently t

We still remember that the 80-90% end user response time was spent on various elements on the download page, such as files, style sheets, scripts, and Flash. Instead of focusing on restructuring the system, it is better to distribute static content first. This not only greatly reduces the response time, but also makes it easy to implement distributed static content due to the presence of CDN.CDN is a

. Adapting to a Web site means you don't have to rebuild your site. Instead, you can build existing content while transferring the layout of the mobile response. For an expert-level developer, this approach can also be tailored to specific device or screen resolution. For example, for many mobify online fashion retail customers, their mobile traffic 95% comes from iphones. Client-side adaptation means that they can specifically optimize Apple's smartphone. Unlike the corresponding design, the

research, more than 2019 of users around the world will adopt IPv6 in 50%. The exact number is hard to determine because the data is scattered. Google, Akamai, and APNIC all released their IPv6 traffic measurement results, but their methods and results are different. Google focuses on Cache and search engine results, Akamai focuses on TCP meetings, and APNIC focuses on online ads for inserting network obje

even more profitable than they are.Justin.tv's usher controls the topology of the service by using HTTP requests to control which video stream is loaded by a server. Justin.tv uses HTTP on streaming data, but one problem is that it has no latency and real-time performance. Some people say that the real-time definition is 5-30 seconds, however, this is obviously not possible in the face of thousands of of people doing real-time video, because they also need real-time discussion, communication, w

But surprisingly, in this experiment, traffic and investment were reduced by 20%, apparently because more search results resulted in more than half a second to load the page. ^5The user's expectations are always rising. In 2009, a study by Akamai, a Forrester I

In fact, there are several research reports, which provide several reference time indicators:1. "8 seconds": In the 90 's, the Nielsen study reported that over 8 seconds of waiting time, internet users would lose patience.2. "4 Seconds": In September 2006, the Akamai and Jupiter study reported that online shoppers had

following questions: • Start experimenting with cloud computing with unimportant applications. Some cloud computing can also be used to provide overloaded capacity. • Prepare the business unit to adopt cloud computing. Even if the IT department cannot justify the use of cloud computing, your business unit will be able to prove it. Cloud computing is a tempting business. The infrastructure of cloud computing can be configured with a credit card, and the entry and exit thresholds are low. Don't
