akamai load balancing

The reading and writing separation and load balancing of MySQL database are usually realized by the third party software. It can also be implemented through the MySQL driver, such as Com.mysql.jdbc.ReplicationDriver. Detailed documentation See also: http://dev.mysql.com/doc/refman/5.5/en/connector-j-info.html The code is as follows Copy Code Import java.sql.Connection;Import Jav

1.HAProxy Introduction Haproxy is an open-source, high-performance, load-balancing software based on TCP (four-tier), HTTP (seven-tier) applications. That haproxy as a professional load balancer software, it has the following advantages: Very good reliability and stability, comparable to hardware-level F5 load

Summary : For a large web site, load Balancing is an eternal topic. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 big-IP, Citrix NetScaler, Radware and so on, although can solve the problem, but its high price is often prohibitive, So

There are three different ways to deploy Apache as a loadbalance predecessor, respectively: 1 The allocation of polling equalization strategy Enter Apache's conf directory, open the httpd.conf file, and add at the end of the file: proxypass/balancer://proxy/#注意这里以 "/" End Balancermember http://192.168.6.37:6888/ Balancermember http://192.168.6.38:6888/ Let's look at the parameter "proxypass/balancer://proxy/" above, where "Proxypass" is the command to configure the virtual server, "/" to rep

Load balancing algorithms can be divided into two categories: Static load Balancing algorithm, server-based capacity, is a high-configuration server than the low-provisioned server to allocate more requests, dynamic load balancing

First, HAProxy 1.haproxy Introduction HAProxy is a free, fast, and reliable solution that provides high availability, load balancing, and proxy software based on TCP (layer fourth) and HTTP (layer seventh) applications that support virtual hosting. Haproxy is a free and open source software written in C language Haproxy is especially useful for Web sites that are heavily loaded, and often requ

In many existing network applications, sometimes a server cannot meet the requirements of the client. In this case, you can only add servers to solve the problem. Is there a way or technology to solve this problem? Use the network load balancing cluster in Windows 2000 or Windows Server 2003 (This article describes how to implement the Network Load

For a large web site, load Balancing is an eternal topic. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 big-IP, Citrix NetScaler, Radware and so on, although can solve the problem, but its high price is often prohibitive, So

18.6 Load Balancing Cluster introduction Main open source software LVs, keepalived, Haproxy, Nginx, etc. The LVS belong to 4 layer (network OSI 7 layer model), Nginx belongs to 7 layer, Haproxy can be considered as 4 layer, can be used as 7 layer The Keepalived load balancing function is actually the L

Summary Super Load balancing is designed to improve the stability of the system and distribute the request pressure automatically to solve the problems such as the continuous expansion of service, the increasing of machines and the difference of machine performance. The algorithm realizes a number of models and equalization strategies, which can be configured to achieve random, polling, consistent hash a

1. Cluster (Cluster): A group of independent computer systems that form a loosely coupled multiprocessor system that communicates between processes through the network. Applications can communicate over a network of shared memory to implement distributed computers. 2. Load balancing (Load Balance): Start with the cluster, the cluster is a group of connected comp

Multi-core CPU, to play a good performance of multiple CPUs, you must ensure that the task assigned to each CPU has a good load balance. Otherwise some CPUs are running, others are idle and cannot play the advantage of multi-core CPUs. There are usually two scenarios for achieving a good load balance, one is static load bala
