business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in front of the cluster to achieve traffic distribution.
Load Balance (SLB) balances the

systems. Distributed and business splitting solves the problem from centralization to distribution. However, each deployed independent business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in front of the c
can be achieved [2]. In reverse proxy mode, you can apply the optimized load balancing policy to access the idle internal server each time to provide services. However, as the number of concurrent connections increases, the load on the proxy server itself becomes very large, and the reverse proxy server itself becomes a service bottleneck.

Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and
F5 is one of our most popular Server Load balancer products, so here we will introduce its configuration on the actual business platform. Through this case, I hope you will have a clear understanding of the specific use and configuration of this product. For more information, please refer to the following section.I.

Based on the huge network structure, the use of cluster servers brings a lot of traffic and other load problems. In contrast, Server Load balancer technology has also emerged. Every technology requires Product Support. Now let's get to know one of F5 Server Load balancer. Fi

Based on the huge network structure, the use of Cluster Server brings a lot of load problems such as traffic. So the relative, load-balanced technology also emerged. Each technology requires product support, so let's now look at one of the F5 load balancers. So first of all, we first introduce the structure of the product function.Many vendors have launched a
