Objective: With the explosive growth of Internet information, load balancing (loading balance) is no longer a very unfamiliar topic, as the name implies, load balance is to spread the load to different service units, not only to ensure the availability of services, but also to ensure that the response fast enough to give users a good experience. Fast-growing traffic and data traffic have spawned a wide range of load-

AJP protocol stack. It is developped in httpd-2.1and integrated in it. We have also developed a new proxy_balancerModule for load Balancing HTTP and AJP protocol stacks. JK'll is fully supported for all other Web servers.The next JK release are planned for the ' end of November.Lots of code from JK2 has been ported to JK 2.tomcat Cluster Mode:A.deltamanager--The way it is now used: internal machine clusters are less usedB.backupmanager*************

Four common methods for server load balancing in enterprisesIn order to improve the performance and workload of the server, enterprises usually use the technology of DNS server, network address translation and so on to realize multi-server load balancing, especially the Internet web sites of enterprises outside, many of which are through several servers to complete server access load balance.At present, the

Absrtact: This paper discusses the load balancing technology used in distributed network server and the strategy of load distribution, and realizes the load balance gateway on FreeBSD based on network address translation, which is applied to our Internet network server and distributes the load to multiple servers. To address the high load on CPU or I/O caused by large amounts of concurrent access to Internet servers. To achieve optimal load

The size of the Internet doubles every one hundred days. The customer wants to achieve uninterrupted availability within 7 days and fast system response time, rather than repeatedly seeing a site "server too busy" and frequent system faults. As the business volume increases, the traffic volume and data traffic increase rapidly, the processing capability and computing strength of each core part of the network also increase, making it impossible for a single device to undertake. In this case, if

I. The concept of clustering and load balancing (i) the concept of clusters A cluster (Cluster) is a loosely coupled collection of compute nodes consisting of two or more node machines (servers), providing a single customer view of network services or applications (including databases, Web services, and file services), while providing a fault recovery capability close to a fault-tolerant machine. The cluster system is generally connected through the

thousands of IOPS capacity, the single-machine IO capability has exceeded the traditional disk storage. However, what has been bothering us is how to solve the high availability of Oracle databases in a shared-free storage environment? Our team has designed a framework that provides simple, reliable, and highly available functionality.While in Oracle's position it is always advisable for customers to be better able to plan their own applications, when there are other load

Process | solve | problems Environment Description: Development platform is dotnet b/S. NET Framework 1.1 The official web server and test machine are win2003 The original main web site, in six Web servers to do load balancing. Run more stable. A new sub station is now being developed to load balance on another three Web servers. This load balancing setting is similar to the settings for the main web site.

In the past, running a large Web application meant running a large Web server. Because your application attracts a large number of users, you will have to add more memory and processor to your server. Today, the "big server" model is over, replaced by a large number of small servers, using a variety of load balancing techniques. The advantages of "more small servers" over the past "large server" model are embodied in two aspects: 1. If the server is
