Web Server Clustering

Intelligent management includes application versioning, dynamic clustering, health management, and intelligent routing. This article mainly introduces you to application version management. IBM released the WebSphere creator Server (WAS) V8.5 on June 15, 2012. A major change in was V8.5 is the complete incorporation of the functionality of the previously independent product WebSphere Virtual Enterprise (hereinafter referred to as WVE) into ...

What is Cluster? There are two common Cluster (clusters) architectures, one is Web/internet Cluster system, which is to place data on different hosts, that is, multiple hosts are simultaneously responsible for one service, and the other is the so-called parallel operation! Parallel operation is actually the work of the same operation, to the entire Cluster inside the CPU to perform a synchronous operation of a function ...

What is a cluster? There are two common cluster architectures, one is web/internet cluster system, which is to place data on different hosts, that is, multiple hosts are responsible for one service at the same time, and the other is the so-called parallel operation! Parallel operation is actually the work of the same operation, to the entire Cluster inside the CPU to perform a synchronous operation of a function. Due to the computational power of using multiple CPUs ...

In order to improve the performance and workload of the server, enterprises usually use DNS server, network address translation technology to achieve multiple server load balancing, especially the current enterprise external Internet Web site, many are through several servers to complete the server access load balance. The current enterprise uses the so-called "load balancing server", in fact it is a control server of the application system, all users request first to this server, and then the server according to the actual processing server-like ...

In the business and enterprise network, generally are mining C mode, that is, "client-server" mode, according to the authority of the investigation and prediction, the future of the network development also shows the trend of centralized computing. 　　And the rise of data center to the server configuration density put forward more and more high requirements, it is in this situation, in order to break the limit of individual performance of the server, a new generation of clustered server-blade server. With the further development of large-scale computing and network server requirements for parallel processing capabilities, "collective power" to cast a powerful processing power blade server has been ...

The server is actually a combination of software and hardware, from a broad perspective, it can achieve two functions one is to store the entire http://www.aliyun.com/zixun/aggregation/32416.html "> The information in the network system so that other access to the network, followed by the ability to access the information of the front-end devices from the existing information to provide the required information. It can be said that the server is the whole network system in the heart, to ensure the efficient work of the entire network system ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Blade servers have become the mainstream of high-performance computing clusters, with many new cluster systems using blade architectures in the world's Super 500 and top 100 supercomputers. As a result of the use of blade server can greatly reduce the number of external cables required, can greatly reduce the cable connection fault caused by the hidden trouble, improve the system can ...

On the surface, the concept of clustering is not difficult to understand. Clustering is a new technology that joins multiple computers together to form a whole, thus making better use of device resources. Ira Kramer, marketing director of Infinicon Bae, said: "A server cluster joins multiple physical servers in a variety of cluster architectures to work in a distributed cluster." 　　The company provides cluster management equipment and services. The mystery remains understandable. When technical terminology in the engineer and market http://...

Computing the number of cluster projects in Linux is like counting the number of startups in Silicon Valley. Unlike Windows NT, which is already hampered by its own closed environment, Linux has a large number of cluster systems to choose from, suitable for different purposes and needs. 　　But it is not easy to determine which cluster should be used. Part of the problem is that terminology clusters are used on different occasions. IT managers may be concerned with how to make the server run longer or to make the application run faster, while mathematicians may be more concerned with large numbers on the server ...
