network data processing capabilities, and improve network flexibility and availability. 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

mainly implements the following tasks: solving network congestion problems, providing nearby services to achieve geographic location independence, providing users with better access quality, and improving server response speed; this improves the utilization efficiency of servers and other resources, and avoids spof in key parts of the network.For Server Load balancer applications of a network, you can star

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

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

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

Use Network address translation to achieve multi-server load balancing. Abstract: This article discusses the server load balancer technology and load allocation strategies used by distributed network servers, and implements the server load

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load balancing system will stop requesting the server to go down and distrib

Linux Server load balancer-load average In the previous article, we introduced how to use the w command or the uptime command to view the average Load (avaerage) of the Linux system. What is the normal status of the average Load? How should we define the stability of the sys

This article discusses Tomcat's support for cluster, Server Load balancer, fault tolerance, session replication, and other capabilities. In this section, we will se

log cannot be written to the problem that eventually causes the entire application to crash.3. Logging to logging server you can use a logging software, such as a syslog, to write all the logs to a central server. Although this method requires more configuration, he also provides the most robust solution. PHP Load Balancer Instance If you want to use load balanc

QoS function, the router provides different levels of priority processing capabilities for data exchange for specific business applications.　　3. Use layer-4 switching technology to achieve server load balancingThe following design comes from the practical application of the network center of a Network Education College in a university. The layer-4 switch of Alteon provides Server

After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely. Background: Use Nginx and two Tomcat servers to achieve load balancing, disable tomcat ports (8080 and 8090) in the firewall, and open only port 80 to the

Currently using a hardware load balancer as an Exchange deployment scenario, using a hardware load balancer a good advantage is that the load of the application can be distributed more evenly to the servers in each backend, there
