f5 virtual load balancer

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

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

The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance te

logical link, which is the link aggregation Trunking) technology. It is not an independent device, it is a common technology used by switches and other network devices. As you can see, traditional Server Load balancer is only a load balancing technology. Currently, in the face of complex network application requirements, the independent Server

rules and policies on our routers can only be routed to a specific group, that is, to a virtual group, which is not a specific physical server. The next thing to do is to find a specific physical DB server for specific data manipulation. Based on the requirements of this link, we introduced the concept of load balancer (LB). The responsibility of the

implementation and configuration and maintenance process is more complex, relatively speaking, nginx/haproxy+ Keepalived is a lot easier. HAProxyfeatures of Haproxy: Haproxy is also supported for virtual hosts. The advantages of haproxy can be supplemented with some of Nginx's shortcomings, such as supporting session retention, cookie guidance, and the ability to detect the status of the backend server by obtaining the specified URL

to happen). Before we introduced the cluster, our first query process was roughly the following: requesting the data layer and passing the necessary library-differentiated fields (typically user_id). The data layer carries out data operations within the defined DB based on the differentiated field route to the specific DB. This is not the introduction of the cluster, when the introduction of the cluster will be like it? The rules and policies on our routers can only be routed to a specific grou
