With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load Web Services.Under the idea of Server Load
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, softwa
Server planning: The entire system in the RHEL5U1 server 64-bit version, by the Xen-based virtual machine, wherein the cluster management node * 2, SQL node * 2, Data node * *, Web Service node * *, the data node is made up of 2 groups, each group of two units of the form:
Virtual machine mysql_mgm-1, 192.168.20.5: Cluster Management node, id=1

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. Server Load
Generally, server load balancer distributes client requests to various real backend servers to achieve server load balancer. Another method is to use two servers, one as the Master and the other as the hot backup ),

Server Load balancer allocates the load to the machine that goes down. In this way,
The Fault Tolerance problem is solved. Therefore, we introduced the concept of cluster and embedded it into our framework to become part of the framework.
As shown in, the entire data layer consists of three clusters: Group1, Group2, and group3. these three clusters are the resu
One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t

I. apache server load balancer is actually very powerful in operating apache. Recently, I have studied apache reverse proxy and server load
, improving 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, computing of a single heavy load is distributed to multiple nodesPoint devices perform parallel p

The more famous is www.linux.com and www.real.com.II. system Structure of LVSThe server cluster system with LVS is composed of three parts: the most front-end load Balancing layer (Loader Balancer), the middle server group layer, with server array, the lowest data sharing storage layer, represented by shared storage. All applications are transparent to the user, and the user is only using the hig

First, let's take a look at the layer chart of the TCP/IP protocol family that everyone is very familiar with: the role of each layer in the network packet transmission process is not the focus of this article, this article mainly explains how to use IP addresses at the network layer for server cluster load balancing and why it can be used for
Origin:Because I plan to develop a server similar to instant messaging, I need to plan the framework for future development. The most important solution is to connect the client to the server. As the number of customers increases (for example, 1 million), online and offline (for example, 10 thousand) at the same time will put a lot of pressure on the system. In addition, Server Load balancer should be consi
Because the data traffic of the network is mostly concentrated at one end of the central server, load balancing is usually used to balance (or share) the load of the accessed server. Server Load balancer is structured into local Server Load
