f5 load balancer configuration

Reprint: http://www.zyan.cc/f5_big_ip/In the recent comparison of testing the performance of F5 big-IP and Citrix NetScaler load balancers, write this article to document the common application configuration methods for F5 big-IP.Currently, many vendors have launched a load

If the squid cache misses, the F5 intranet virtua

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

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

After configuring Nginx, when accessing Tomcat, Tomcat displays such as: From this state can be seen, guess is CSS and JS these files are not loaded. In addition, access to the pages deployed on the Tomcat project is the same, with different nginx accesses to the project under Tomcat such as: Through Nginx as a proxy server, access to the page is like this: These conditions are obviously due to the server through Nginx as load

Load balancers are often referred to as four-tier switches or seven-tier switches. The four-layer switch mainly analyzes the IP layer and the TCP/UDP layer to achieve four-layer flow load balancing. In addition to supporting four-tier load balancing, the seven-tier switch also contains information on the analysis application layer, such as HTTP protocol URI or co

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission. I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking mode enables complete master-slave switchover.

servers provide services, but the domain name is resolved only to the master server, and the real server IP address is not obtained by ping, increasing security. 3. the IP address in upstream is not necessarily an intranet IP address, and the Internet IP address can also be used. However, in the classic case, a certain IP address in the Lan is exposed and the domain name is directly resolved to this IP address. The master server is then forwarded to the IP address of the intranet server. 4. a s
