dns round robin load balancing

optimized load distribution policy to achieve the purpose of evenly distributing the load. Keywords: server load balancer, network address translation, FreeBSD 1. Introduction The rapid growth of the Internet allows the multimedia network server to rapidly increase the number of accesses, and the server must be able to provide a large number of concurrent ac

way, and the server cluster software implemented in this way is less. In some cases, CGI (including the use of fastcgi or Mod_perl extensions to improve performance) can be emulated to share the load, while the Web server remains simple and efficient, and the task of avoiding the location cycle will be borne by the user's CGI program. 2. Load balancing of Base

device in front of the cluster to achieve traffic distribution.Load Balancing (Balance), which means that load (work tasks, access requests) are balanced and distributed across multiple operating units (servers, components) for execution. is the ultimate solution for high-performance, single-point-of-failure (high availability), scalability (horizontal scaling).This article is the first article on

Load BalancingMainstream open source software: LVS, keepalived, Haproxy, Nginx and so on;OSI Layer: LVS (4), Nginx (7), Haproxy (4, 7);The Keepalived load balancing function is actually the LVSLVS Load balancer can distribute other ports than 80, such as MySQL, while Nginx only supports HTTP, https, mail;LVS Introducti

IntroducedLoad balancing is a common technique for optimizing resource utilization across multiple application instances, maximizing throughput, reducing latency, and ensuring fault tolerance.Nginx supports the following three types of algorithms:Round-robin: Request loop release to each machineLeast connected: The next request will be sent to the server with the least number of active connectionsSession Pe

protocols, such as the Outlook Web App. So on the load balancer this layer, no longer special need for the load office weighing products to support client affinity.Let me say a few more words, from the level of the mailbox connection to the level of the Web connection request. As mentioned earlier, older versions of Exchange have problems requiring clients to re-authenticate without client affinity support

Website access speed and enhancing website availability and security. DNS round robin and squid reverse proxy can be used to achieve Load Balancing for websites, thus improving the availability and reliability of websites. The reverse proxy server is also called the Web Acceleration Server.It is located at the front e

F5-BIG-LTM-3600-4G-R 3.Load Balancing for Wan Server Load balancer is mainly applied to some large websites, and some people call it Remote Server Load balancer. for example, we have two Web servers, one at the Beijing IDC (China Netcom) and the other at the Guangz

Client1 and Client2 are as follows: server { listen 80; server_name www.zzl.com; OK. After setting, load your nginx reload nginx-s reload. This is the success !!! How to distribute multiple nginx instances and achieve Load Balancing for large domestic websites? This information is basically incomplete. Let me talk about a basic architectu

rich set of features for DNS integration that has become increasingly popular. Other popular options are the use of distributed and replicable Key-value storage, such as ETCD in which services can register themselves. Apache Zookeeper will also be aware of the need for such a group of people. In this article, we mainly deal with some of the mechanisms provided by Docker swarm (Docker in swarm mode) and demonstrate the service abstraction we explored

service provision. Because the performance of a single server is always limited, multi-server and load balancing technologies must be used to meet the needs of a large number of concurrent accesses. The earliest load balancing technology was implemented through DNS. In

Several implementation ways of Web load balancingSummary:Load Balancing (Balance) is an application of cluster technology (Cluster). Load balancing can spread the work tasks across multiple processing units, increasing the concurrency processing power. The most common application for

The load master can provide many kinds of load balancing methods, that is, we often call the scheduling method or algorithm:Round robin (Round Robin)This method loops the received requests to each machine in the server cluster, which is the active server. If this is the case

initial basic design concept for using Server clusters to achieve load balancing. The new solution is to translate different IP addresses of multiple server NICs into a Virtual IP Address through LSANT (Load Sharing Network Address Transfer), so that each server is always in the working state. The work originally needed to be done with a minicomputer was complet

There are many ways to load balance the web, and here are a few common load-balancing methods. 1. User manual Selection method This is an older way. Load balancing is achieved by providing different lines and different server connections in the main home portal. This approac

idea is to use the Server Load balancer function of the reverse proxy server. The varnish mentioned in the previous article supports this function and view the configuration file: Backend web1 {. Host = "192.168.0.77 ";. Port = "8081 ";}Backend web2 {. Host = "192.168.0.77 ";. Port = "8082 ";}Director lb round-robin {{. Backend = web1;}{. Backend = web2;}}Sub vcl_recv {Set req. backend = lb;Return (pass );

1.http REDIRECT Load BalancingThe HTTP redirect server is a normal application server whose only function is to compute a real Web server address based on the user's HTTP request and write the Web server address to the HTTP redirect Response (location header)The status code is 302, which is returned to the user's browser. Both the load server and the Web server are the IP of the public network.This kind of
