fortigate load balancer virtual server

server load balancer: the real physical server is returned to the server load balancer. There are two methods: (1) the server

capability. However, some data shows that most vswitches no longer have a layer-4 switching capability at such a high speed, only layer-3 or layer-2 exchange is supported. 　 However, for most sites, the current load balancing mainly solves the bottleneck of the Web server's processing capability, rather than the network transmission capability. The total Internet connection bandwidth of many sites is less than 10 MB, only a few sites can have high-sp

front-end is the Server Load balancer, which is responsible for distributing various service requests to the subsequent physical servers, so that the entire cluster is like a virtual server serving the same IP address.3. Operating Principles and advantages and disadvantages

lot of practical, in addition to the solutions provided by some vendors, A more effective way is to use free software to complete this task. This includes the NAT Implementation Method in the Linux virtual server project, or the revised version of natd under FreeBSD. Generally speaking, this software method is used to implement address translation. The bandwidth limit of the central

policy Go to the conf directory of Apache, open the httpd. conf file, and add the following content to the end of the file: Proxypass/balancer: // proxy/# note that it ends "/"Balancermemberhttp: // 192.168.6.37: 6888/Balancermemberhttp: // 192.168.6.38: 6888/ Let's observe the above parameter "proxypass/balancer: // proxy/", where "proxypass" is the command to configure the

balancer modifies the source address while modifying the destination IP address. Set the source address of the data packet to its own disk, that is, the source address conversion (snat ). (2) use the server load balancer server as the gateway

balancing 1. network load balancing allows you to spread incoming requests to up to 32 servers, that is, you can use up to 32 servers to share external network request services. Network Load Balancing Technology ensures that they can respond quickly even when the load is heavy. 2. Only one IP address or domain name must be provided for external network

Original English version, Chinese versionTony TangTranslation Arrangement In the first part, I briefly described the various factors that need to be taken into account during the design of a large J2EE system with upgrading and high reliability. This article discusses Tomcat's support for cluster, Server Load balancer, fault tolerance, session replication, and ot

(usually user_id )? How does the data layer differentiate fields from Route to a specific DB? Perform data operations in the specified DB. This is because no cluster is introduced. What will it look like when a cluster is introduced? As shown in figure 1, we can see that the rules and policies on our routers can only be routed to a specific Group, that is, only one virtual Group can be routed. This Group is not a specific physical

Linux Server load balancer-load average In the previous article, we introduced how to use the w command or the uptime command to view the average Load (avaerage) of the Linux system. What is the normal status of the average Load?

traffic. LVS only distributes requests, but the traffic does not go out of it. This ensures that the I/O performance of the balancer will not be affected by the large traffic.5. a wide range of applications. because LVS works on layer 4, it can load balance almost all applications, including http, databases, and online chat rooms. LVS has the following disadvantages:1. the software itself does not support

Nginx series ~ Implementation of Server Load balancer and WWW server, nginx Load Balancing The last two lectures are mainly about the Nginx environment, which does not involve the development of the real environment. In this example, describe how to configure Nginx for the

Defined:LVS is a shorthand for Linux virtual server, that is, a virtualized server cluster system.Structure:In general, the LVS cluster uses a three-tier structure, the main component of which is: A, Load Scheduler (load balancer)

packets into small data segments and distribute them to multiple parallel lines. It can also dynamically allocate dialing lines based on the current Link Utilization. Although the speed is very slow, because packet segmentation and additional buffering increase latency, it can run well on low-speed lines.The link aggregation system increases the complexity of the network, but also improves the reliability of the network, so that people can use redundant routes on the lines of key LAN segments s

each of the four servers. The remaining IP address is called "virtual IP Address", which is used to share the two Server Load balancer nodes. Architecture details The configuration information is as follows: Server Load

Main module Below a main area, he is a global setting: User nobody nobody; Worker_processes 2; Error_log/usr/local/var/log/nginx/error.log notice; Pid/us

. The complete network load balancing and high availability network technology are composed of two aspects: one is multi-server binding and load balancing, and the other is a server load balancer bound with multiple NICs, here we
