best load balancer software

The server Load balancer described in this article is used to balance client requests among multiple nginx processes. Note the difference between Server Load balancer and client requests on multiple backend servers. The problem of Server Load

Recently want to be able to configure load balancing, in the virtual machine above, but the Internet to find a lot of information is fragmented, for people who do not know, a lot of not enough detail, recently finally done, the specific steps to write down, convenient for you to read the studyThis experiment requires the installation of Nginx if not installed, please refer to:Linux installation nginx:http://www.cnblogs.com/aspirant/p/6714548.html(1) O

Nginx Server Load balancer transmits the parameter method to the backend (the backend is also an nginx server), and nginx Server Load balancer A website uses nginx for load balancing and multiple nginx servers at the backend. Encountered a problem, when it is used as SSL sup

Apache + Tomcat server Load balancer configuration and tomcat server Load balancer Apache + Tomcat server Load balancer ensures high availability and system performance, which is achieved through communication between Apache and

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

Five Policies for configuring Server Load balancer using nginx in the production environment: nginx Server Load balancer Nginx upstream currently supports five allocation methods1. Round Robin (default) Each request is distributed to different backend servers one by one in chronological order. If the backend servers ar

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

, and there are few server cluster software implemented using this method. In some cases, you can use CGI (including FastCGI or mod_perl extension to improve performance) to simulate this method to share the load, while the Web server still maintains a concise and efficient feature, in this case, the user's CGI program is responsible for tasks that avoid Location loops. 　 　　 2.

support functions related to server load balancer, such as the redirection capability in HTTP, but they depend on specific protocols, so the scope of use is limited. Based on the existing server load balancer technology, we chose the server load

parameter to verify the validity of the cluster node. To use this class, make sure that the catalina-cluster.jar (located in the % tomcat_home %/Server/library directory) And the commons-logging-api.jar (located in the % tomcat_home %/bin directory) file is specified in classpath.

Nginx series ~ Implementation of Server Load balancer and WWW server, nginx Load Balancing The last two lectures are mainly about the Nginx environment, which does not involve the development of the real environment. In this example, describe how to configure Nginx for the Server Load

load balancing policy1. Server Load balancer based on specific server software many network protocols support the "redirection" function. For example, HTTP supports location commands, the browser that receives this command will automatically redirect to another URL specified by location. Since sending location command

one file. The benefits are simple, possibly as long as there are few configurations. However, as the number of servers increases, it becomes very difficult to monitor log files on each server. 2. Logging to a share this method is still available for each server, but they are stored on a central file server through a sharing mechanism, which makes monitoring logs easier. The problem with this scenario is that if the file server is unavailable, a simple log cannot be written to the problem that e

Now, basically all enterprises use the network for daily work. In the network operation of an enterprise, the transmission and data sending and receiving processes are not evenly distributed. Then, using Server Load balancer technology can achieve a balanced concept. So how to implement it? If it is not realistic to purchase large load balancing equipment,

Server Load balancer SLB Load Balance is built on the existing network structure. It provides a cheap, effective, and transparent method, to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability.
