CDN Load Balance [1] As the core components of the existing network increase with the increase of business volume and the rapid growth of traffic and data traffic, the processing capability and computing strength also increase accordingly, making a single server unable to bear. In this case, if you discard the existing device to perform a large number of hardware upgrades, this will cause a waste of existi

In network applications, "Server Load balancer" is no longer a new topic. From hardware to software, there are also many ways to achieve Server Load balancer. The server Load balancer d

Ps:nginx/lvs/haproxy is currently the most widely used three load balancing software, I have been implemented in a number of projects, reference to some information, combined with some of their own experience, summed up. The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and mediu

request is sent, and then send the request to the server. Client-Based Load Balancing features: Implemented by the internal program of the client, without the need for additional hardware and software investment of the Server Load balancer. The program must solve the problem of Service Server unavailability, And th

. This article discusses how to implement the balancing of multiple network interfaces and failover. II. Introduction to server load balancer technology and high availability technology 2.1 Server load balancer technology the main idea of server load

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load

Server Load balancer algorithms forward HTTP requests to different processing servers. ARR is used as follows:ARR is based on the URL Rewrite Module. It detects HTTP requests sent from the client to make request routing decisions. 650) this. width = 650; "border =" 0 "alt =" 20120326103946.png" src = "http://www.agilesharp.com/Services/BlogAttachment.ashx?

systems or different hardware. For example, a cluster that provides Web Services is a large Web server. However, cluster nodes can also provide services separately.3. Features: based on the existing network structure, Server Load balancer provides a cheap and effective method to expand server bandwidth and increase throughput, enhance network data processing cap

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. It uses some tools to analyze data packets in real time, master the

Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind

service (FAN) immediately notifies the client to reconnect with other VIPs. The client selects other VIPs in tnsnames. ora to continue the attempt until the connection is successful. Can I use an IP address to connect directly without using the vip connection? The answer is yes, but it takes 30 seconds to notify the client after the connection fails. The price of 30 seconds is too high, and the meaning of high availability is completely lost. The

Nginx/lvs/haproxy is currently the most widely used three load balancing software, the general use of load balancing with the increase in the size of the site according to different stages of the use of different technologies, specific application needs to be specific analysis. if it is a small and medium-sized Web application, such as the day PV less than 10 million, with Nginx can be completely, if a lot

Lower management costs, making shared host deployment possible ARR is based on the URL rewrite module. It detects HTTP requests sent from the client to make request routing decisions. Next, let's take a look at some features of ARR: 1. Request Routing decisions made based on HTTP requests Unlike

I. Concepts of reverse proxy and Server Load balancer Before understanding the concepts of reverse proxy and Server Load balancer, we must first understand the concept of a cluster. Simply put, a cluster is a server that does the same thing, such as a web cluster, database cluster, and storage cluster, the cluster has

Preface: The company has developed a website. The estimated maximum number of online users is 30 thousand, and the maximum number of concurrent users is 100. Whether or not the developed website can withstand this pressure and how to ensure that the load of the website is no problem, after research, it is decided as follows: (1) Server Load balancer and cluster t
