weighted load balancing

In regular operations, load balancing services are often used. The load balancer is divided into four-layer and seven-tier loads, so what's the difference between the two? Needless to say, the following are detailed:One, what is load balancing1)

A　　Simple understanding of four-and seven-layer load balancing:　　① The so-called four layer is based on the ip+ Port load balancing, seven layer is based on the URL and other application layer information load balancing; In the same way, there are

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

There is a big difference between cluster, distributed and load Balancing in PHP, the following article I will give you specific to write a cluster, distributed and load-balanced between the specific differences, say not much, let us take a look at

ContextYou have decided to use clustering when designing or modifying the infrastructure layer to maintain good performance while adapting to changing requirements.ProblemWhile maintaining an acceptable level of performance, how can you design a

The difference in principle between one or four-layer and seven-layer load balancingdiagram:Four-tier load balancing and seven-layer load balancing are simple differences in how they work:Overview:1. Four-layer load balancing works in the OSI model

SummaryThis article mainly discusses the basic balancing algorithms and dynamic load balancing mechanisms in the network load balancing cluster system. Based on LVS, the poll algorithm is used to implement the dynamic negative feedback mechanism of

Load BalancerIt can be a dedicated device or an application that runs on a common server. Distribute requests to servers that have the same content or provide the same services. Special purpose devices are generally only Ethernet interfaces, which

This paper is the fourth of load balancing, mainly introduces the three request forwarding modes and eight load balancing algorithms of LVS, as well as the features of Haproxy and load balancing algorithm. For specific reference articles, see the
