Discover how f5 load balancer works, include the articles, news, trends, analysis and practical advice about how f5 load balancer works on alibabacloud.com
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
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
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
As a Linux/Unix system engineer, I have been involved in external projects over the past few years. I have worked on the architectures of many small and medium-sized websites. F5, LVS, and nginx have many contacts, I want to explain to you what Server Load balancer is and what is a Linux cluster in a simple and easy-to-understand tone, to help you get out of this

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
