The first introduction to E-commerce Web site high-performance, highly available solutions. From the frame composition of the scheme, the application is lvs+keepalived load balance. Achieve high-performance, highly available solutions (server clusters, load Balancing, high-performance, highly available, highly scalable server cluster)
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

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Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques.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

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

3-2 ajp13 type Worker attributes:
When ajp13 type worker is working, the ajpv13 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process.
The ajpv13 protocol is significantly different from the ajpv12 protocol:
* Ajpv13 has a richer binary protocol. it uses the frequently used string encoding method to compress the request data.
* Ajpv13 reuses opened sockets and retains these opened sockets to handle future r

In the first part, I briefly described the various factors that need to be taken into account during the design of a large J2EE system with upgrading and high reliability.
This article discusses Tomcat's support for cluster, Server Load balancer, fault tolerance, session replication, and other capabilities.

Many vswitches now provide the layer-4 switching function, which can map an external IP address to multiple internal IP addresses and dynamically use one of the internal addresses for each TCP connection request to achieve load balancing. Some protocols support functions related to Server
