Enterprise Network http://www.aliyun.com/zixun/aggregation/15818.html "> Application Server Problems:
1, Network application server reliability is poor:
Application server due to the stability of server hardware, traffic pressure overload, network attacks and other situations often occur unexpected downtime, which can not guarantee network
Application 7x24-hour continuous service.
2, the network application performance bottleneck:
In a network application system, more than one server is usually used to provide services at the same time. However, due to the uneven flow of traffic in the network, it often occurs that a server is down because of the large number of accesses, resulting in the instability of the network application performance, thus affecting the performance of the whole network application system.
Solution:
We can deploy a server load balancer on the intranet, as shown in the following illustration:
The server can be deployed on the front-end of the application server or anywhere in the network, so that user access is first through the load balancer, and the load balancer assigns the user's request to the real server according to a predetermined load balancing algorithm. If a server fails (hardware and software), the load balancer can be detected in a timely manner, so that new user requests are assigned to a working server, thereby preventing the business from being affected by server failures.
Programme features:
Improve application server performance and reliability
Through a variety of load balancing algorithms to enable application services to maintain a high performance
Through health check, load balancer can detect the server working condition, and the working condition of the application software, to guarantee the reliability of the enterprise application.
Users can maintain the server when they work on the application server, including adding and reducing servers and not interrupting applications.
