the environment. 4. E-commerce Web site High-performance, highly available solutions, LVS load balancing (front-end four-tier load balancer). 5. The key point explanation of the construction process, the key step explanation. 6. This program has been used in practical production applications for many times, and can be flexibly applied. Second, the software

must be used to meet the needs of a large number of concurrent accesses. Linux Virtual Server (SERVERS,LVS) uses load balancing technology to make multiple servers a virtual server. It provides a cost-efficient solution for adapting to fast-growing network access requirements with a load capacity that is easy to scale. LVS is an open source software that enables

or avoiding the bottleneck of unbalanced network load distribution and long response time of data traffic congestion. For different Server Load balancer modes, Layer 2, Layer 3, Layer 4, and Layer 7 Server Load balancer of OSI reference models have corresponding Server Load balancer policies. =^The advantages and disa

This is a creation in Article, where the information may have evolved or changed. 1) Introduction The main implementation mechanism for GRPC load balancing is external load balancing, which is to provide the client with an updated list of servers through an external load bal

Basic load balancingAlgorithm, Mainly including the following (refer to F5 products ): Random: The Load Balancing Method Randomly distributes the load to each available server, selects a server through the random number generation algorithm, and sends the connection

IP Tunneling) is proposed through IP Tunneling ), and Virtual Server VS/DR (Virtual Server via Direct Routing) through Direct Routing, which can greatly improve system scalability. 2.1 VS/NAT Mode After the request sent by the client reaches Director, dire modifies the target address to a backend RIP (one of the hosts in the web server pool) based on the Load Balancing Algorithm and forwards it to the back

IP address to the same server during the same session, and implement session stickiness.Disadvantage: The session is lost after the target server is down;3.5 weightingOn the basis of polling, random, least-link, Hash ' Algorithms, the load server is allocated by weighting the way.Advantages: According to the weight, the number of requests to adjust the forwarding server;Cons: use is relatively complex;Four, hardware

the original round robin algorithm, added a program for collecting dynamic weights and fed back it to the Load balancer's scheduling system in real time. Practice has proved that the use of dynamic balancing has improved the overall throughput of the cluster system, especially when the performance of each node in the cluster is different and the network service
