Server Load balancer (SLB) is a load balancing service that distributes traffic among multiple ECs instances. SLB can expand the external service capability of the application system through traffic distribution, and improve the availability of the application system by eliminating spof. (In connection with CDN, CDN uses Server

One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t

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

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), it is the entire cluster to the outside of the front-end machine, responsible for sending the customer's request to a set of servers

5. Installation Configuration keepalivedKeepalived is running on the LVS, its main function is to realize the real machine fault isolation and load balancer between the failure switch Failover.lvs combined with keepalived, the implementation of 3-layer, 4-layer, 5/7-layer switching functions. The following is the second use of LVS, lvs+keepalived. The installation and verification of Ipvsadm is the same as

Server Load balancer Algorithm There are many Server Load balancer algorithms (persistent and non-persistent), including the round robin algorithm, least connection algorithm, response time algorithm, hash algorithm, and least connection error algorithm, link bandwidth algorithms. In addition, the actual se

PS: nginx/LVS/haproxy is currently the most widely used three load balancing software. I have implemented these software in multiple projects. I have referenced some materials and combined some of my experience in using it, to sum up. Generally, Server Load balancer uses different technologies at different stages as the website scale increases. Specific Applica

Network troubleshooting: Consider the Server Load balancer System It may be difficult to eliminate network problems. If a Server Load balancer system is added to the network, it will pose another challenge. It may not be easy to identify whether the Server Load

At present, the development of business volume in Enterprise Networks, campus networks, and wide area networks, such as the Internet, exceeds the most optimistic estimates in the past. The Internet boom is surging and new applications are emerging one after another, even if the network is built according to the optimal configuration at that time, it will soon feel overwhelmed. Especially for the core parts of each network, the large data traffic and computing strength make it impossible for a si

Many websites do not need a large scale at the beginning, but as a website designer, expansion must be taken into account from the very beginning to build a highly scalable architecture. The so-called scalability means that the system can improve the carrying capacity of the system through scale expansion. After all, the vertical expansion of the server itself will soon be restricted, and the single machine will soon be unable to meet our needs, therefore, this capability is often achieved by ad
