load balance

The paper wants to discuss the load balance, which is the load balance between various worker threads (processes) within a multithreaded (multi-process) server program.Consider a common server model: A receiver thread is responsible for receiving requests, followed by a thread pool that contains a bunch of worker threa

Load Balancing (Balance) is one of the factors that must be considered in the design of distributed system architecture.It usually means to allocate the request/data "evenly" to multiple operation units, and the key of load balancing is "uniformity". The uniformity here is not the 10÷2 = 5 we imagined, which is even. No.The Common Internet distributed architectur

LB (load balance) Load Balancer clusterPrinciple: When a user's request comes in, it is sent directly to the dispatcher (Director server), which then distributes the user's request intelligently and evenly to the backend really server (real server) according to the pre-set algorithm. If different machines may request data differently, in order to avoid this situa

Last week sent a questionnaire to see if you have any suggestions for Lao Wang, and then a lot of friends voted to understand the programming technology and server architecture of dry goods, so the next will talk about programming and architecture-related algorithms, And then maybe in late June, I'll talk to you about the interview (Lao Wang has attended about hundreds of interviews and can talk about the interview from the interviewer's point of view). Lao Wang Chat technology has a characteris

Load Balance is one of the most important features of Oracle RAC. It distributes the load evenly to each node in the cluster to improve the overall throughput of the system. Generally, there are two methods to achieve load balancing. One is Load Balancing Based on Client con

request, such as: http://myserver/or HTTP ://MYSERVER/AAA, these URLs will conform to the above filtering conditions, "balancer://proxy/" means to configure load balancing, proxy represents the load balancing name, and Balancermember and its subsequent URLs represent the background server to configure. The URL where the URL is the background server request. Taking the above configuration as an example, the

As the core of the existing network with the increase of traffic volume, the traffic volume and the rapid growth of data flow, its processing capacity and computing strength correspondingly increased, so that a single server equipment can not afford. In this case, if you throw away an existing device to do a lot of hardware upgrades, this will result in the waste of existing resources and, if faced with the next increase in business volume, this will lead to a high cost of hardware upgrades agai

Most websites now use the Server Load balancer technology, which can improve the stability and traffic distribution of websites and speed up access. Is an evolutionary process, from a single server to multiple servers: There are many Server Load balancer technologies on the Internet. Here is a reference: Because the data traffic of the network is mostly concentrated at one end of the central server,

Cluster)A cluster is a loosely coupled multi-processor system composed of a group of independent computer systems. It communicates with each other through a network. Applications can transmit messages through the network shared memory to implement distributed computers.Load Balance)Server Load balancer is a dynamic balancing technology.
