f5 load balancer features

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 medium-sized Web applications, such as the daily PV less than 10 million, with Nginx can be completely; if there are many machines, you can use DNS polling, LVS consumes more machines or more, large web sites or important services, and the server is relatively long, You c

Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often pro

Let's take a look at the configuration file. worker_processes 1; Events {Worker_connections 1024; } http{upstream MyProject {#这里指定多个源服务器, IP: port, 80 port can be written without writing Server 192.168.43.158:80; Server 192.168.41.167; } SERVer {listen 8080;

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

project, cost-effective is much higher than F5, commercial first choice! But in general this phase of the relevant talent to keep up with the business, so the purchase of commercial load balance has become the only way. The ability and quantity of talent is also increased, at this time, regardless of the development of customized products for their own, and reduce the cost of open source LVs, has become th

divide the network segment into only one host address to avoid IP address collisions.3, echo "1", echo "2" The role of this paragraph is to suppress the ARP broadcast. If you do not do ARP suppression, there will be a lot of machines to the other ARP packets to claim that they are true, so it is a mess.6.3 keepalived.conf Configuration InstructionsDescription: A keepalived configuration file that features a complete configuration file keepalived.conf

Currently, F5 type dedicated server Load balancer is the most widely used Server Load balancer device in the data center. You may learn more about Server Load balancer by focusing on DN

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

: Worker. loadbalancer. type = lb Each type has different actions, which will be described below. 3. set Worker attributes: After defining a worker, you also need to provide the attributes of each worker. the following methods are used to define these attributes: Worker .. = 3-1 ajp12 type Worker attribute :. When ajp12 type worker is working, the ajpv12 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process. The attributes of ajp12 worker are as follows: Ho

Server Load balancer solutions include hardware and software solutions. Mainstream hardware solutions: F5 BIG-IP Citrix netscalar A10 A10 Array Redware LVS (Linux virtual server) is a layer-4 network switching or routing software solution. It implements switching or routing through kernel framework module ipvs and a set of rules configured on the framework

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

1. Story ReviewIn my previous blog, I built two Web servers and then built an nginx load balancer server on the front end to distribute the requests to two different servers (http://blog.51cto.com/superpcm/2095324). The previous test is not a problem because the test program is a static web site that is purely static and does not change. Later I set up on both the web to build a WordPress service, and then

F5 is a well-known Server Load balancer product. I believe many people will not know it. So how does it maintain sessions? Let's start with the definition of session persistence. As an image metaphor: Session persistence can be seen as a string of pearls, so we split each Pearl and put it in a different box for storage and then put it into a string, that is, the

devices, buffer servers, and Web servers. How to organically combine these technical devices is a key issue that directly affects network performance. Many vswitches now provide the layer-4 switching function, which can map an external IP address to multiple internal IP addresses and dynamically use one of the internal addresses for each TCP connection request to achieve load balancing. Some protocols support functions related to Server

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
