Windows Apache does load balancing The first time I saw this headline I was surprised that Apache can still do load balancing? It's so powerful. After a survey found that it can, and the function is not bad. This is thanks to the Mod_proxy module. Is worthy of the mighty Apache AH. Less nonsense, the following is to

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

1.http REDIRECT Load BalancingThe HTTP redirect server is a normal application server whose only function is to compute a real Web server address based on the user's HTTP request and write the Web server address to the HTTP redirect Response (location header)The status code is 302, which is returned to the user's browser. Both the load server and the Web server are the IP of the public network.This kind of
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

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

Under the condition that the price of computer hardware declines and the network topology develops, distributed computer system provides a rich collection of resources for users. When people study distributed systems, they notice a problem: In a multiple-computer environment connected by a network, at a certain point, some computers load more heavily, while others are lighter.

The size of the internet increases by one times every 100 days, and customers want to get 7 days and 24 hours of uninterrupted availability and faster system response times, rather than repeatedly seeing a site "ServerToo Busy "and frequent system failures. With the increase of traffic volume and the rapid growth of traffic volume and data flow, the processing capacity and calculation intensity of the network are increased, which makes the single equipment unable to bear. In this case, if you th
Comparison of haproxy lvs nginx Load Balancing For the software that implements load balancing, let's take a look at it in detail. In terms of performance and stability, LVS is the best, basically reaching 60% of the performance of F5 hardware equipment, and other 10% are a little difficult. However, the configuration
