: Anti-load ability, is the work in the Network 4 layer only for distribution, no traffic generated, this feature also determines its performance in the Load Balancer software, the memory and CPU resource consumption is low. Low configuration, this is a disadvantage is also a advantage, because there is not much to

The advantages of LVS are:1, anti-load capacity, is the work in the Network 4 layer only for distribution, No traffic generated , this feature also determines its performance in the Load Balancer software is the strongest, the memory and CPU resource consumption is low.2, the configuration is relatively low, this is a disadva

), and the external router port (Serial Interface) address is the Internet IP address, that is, the NAT Server Load balancer address is required. To handle a large number of WEB connection requests from the Internet, you need to configure NAT Server Load balancer on this vro

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 prohibitive, So

services. The more famous is www.linux.com and www.real.com.II. system Structure of LVSThe server cluster system with LVS is composed of three parts: the most front-end load Balancing layer (Loader Balancer), the middle server group layer, with server array, the lowest data sharing storage layer, represented by shared storage. All applications are transparent to the user, and the user is only using the hig

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 misunderstanding and understand them in the

not controlled by the host, and the speed is fast and low.Take four servers as an example to achieve load balancing:Install and configure LVS1. Preparations before installation:(1) first, LVS does not require uniform server specifications in the cluster. On the contrary, you can adjust the Load Allocation Policy Based on Different server configurations and

the session is not supported, but can be solved by Ip_hash. LVS: Using a Linux kernel cluster to implement a high-performance, highly available load-balancing server with good scalability (Scalability), Reliability (reliability), and manageability (manageability). The advantages of LVS are:1, anti-load capacity, is the work in the Network 4 layer only for distribution, no traffic generated, this feature al

Nginx/lvs/haproxy is currently the most widely used three load balancing software, the general use of load balancing with the increase in the size of the site according to different stages of the use of different technologies, specific application needs to be specific analysis. if it is a small and medium-sized Web application, such as the day PV less than 10 million, with Nginx can be completely, if a lot
