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.

Compare mainstream Server Load balancer instances, such as lvs, f5, nginx, and haproxy! -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Today, most websites use Server Load balancer and reverse proxy software
The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance te
Haproxy configuration for Server Load balancer and haproxy configuration for Server Load balancerCommon Open-Source Software load balancers include Nginx, LVS, and Haproxy. Comparison of three major software load balancers (LVS Nginx VS Haproxy)
I. LVS:1. Strong
Both LVS and Nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to
Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer
Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup;
Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, the operation of a single heavy load is distributed to mul
As a Linux/Unix system engineer, I have been involved in external projects over the past few years. I have worked on the architectures of many small and medium-sized websites.
