The rapid development of Internet changes our work and life style. As people become more and more dependent on the Internet, different industries, different categories of websites are also competing on the line. For organizations that publish business over the Internet, the stickiness of users is affected by access experience to some extent. Especially for e-commerce, this is not just to make money by the flow of the site, the stickiness of users even related to the survival of the site. The more loyal users are, the more easily the products and services they offer will be promoted. Web as the core of the business platform, for the stability of the site, durability and other aspects, usually have higher requirements.
Factors affecting business delivery
Inter carrier access for interconnection between operators has been a bottleneck problem, the electronic commerce website if you publish a single link to the Internet operators, will inevitably lead to other operators when accessed very slowly. As the stability of the Internet link becomes more important today, deploying multiple carrier links helps to ensure the availability and reliability of application services;
The application of system health - with the development of online business website, facing high It is often seen. concurrent access and data flow, processing ability and strength calculation of the core equipment in the system of the burden will increase accordingly, so that a single equipment can not bear. If out of the existing equipment to do hardware upgrades, will result in a waste of resources, and if after face a surge in business volume, and again have to invest a large amount of hardware upgrade costs, even the performance again excellent equipment can not meet the needs of the future business volume;
Server performance pressure - whenever complex computing functions such as SSL encryption and decryption, data compression, etc., the computing resources consumed are a considerable burden for both web and application servers. These complex processing operations directly trap the CPU computing resources, and thus affect the response performance of the business applications. Whether it's a real server or a virtual server, that's an inescapable question;
Remote disaster recovery data center - into a single data center to resist in the face of factors (such as fire, electricity, earthquake), business system is likely to cause significant loss of paralysis immediately, then, many forward-looking organizations in the construction of data center for disaster recovery. Then how to make full use of the resources of multiple data centers to avoid waste of resources? How do you boot a user to a normal data center when a data failure occurs? How do you select the best data center for users when multiple data centers are healthy?
Integrated solution
As a professional application delivery device, AD series can access the best access path of the user's access request and realize the rational distribution of data stream, so that all network resources are fully utilized. Not only to expand the overall processing capacity of the application system, to improve its stability, but also to effectively improve the user's access experience, simplify the deployment program while reducing the site's IT investment costs.
Intelligent DNS routing
• a global IP address library with built-in real-time updates to further improve the accuracy of user requests for nearest distribution and enable the operator to select the best path when accessing the cross operator;
• Considering the multiple factors such as network transmission delay and link real-time load, the best path is calculated accurately.
Server load balancing
• A variety of static and dynamic load scheduling algorithms, based on the choice of the best computing resources for distribution;
• active detection based on application protocols, application content, and multi sensory health inspection mechanisms based on TCP behavior;
• Provides comprehensive session retention methods such as IP, Cookie, HTTP-Header, and Radius.
Web application acceleration
• TCP unilateral acceleration technology to mitigate the impact of network environment instability and optimize data transmission efficiency;
• RAM caching, HTTP compression, reducing the waiting time of user requests, and improving the speed of business access response;
• TCP connection multiplexing, SSL acceleration, reduce server load, enhance application system processing performance.
Multi site redundancy
• Support static and dynamic two kinds of proximity judgment methods, to ensure that users access to the resource is guided to the most appropriate data center;
• monitor the operation of each data center in real time, discover the fault site in time, and transparently guide the user's request to other health sites.
Application value
• reasonably scheduling inbound access from different users, enhancing the stability and user access experience of the external application system;
• Comprehensive health inspection and session keeping mechanism, which can improve the failover ability of server cluster and guarantee the high availability of application system;
• Multi server performance optimization technology to improve the utilization of system resources and enhance the efficiency of Web services delivered over the internet;
• Data redundancy between multiple data centers ensures high availability of the business and improves resource utilization of each site.
