load balancer network diagram

. Therefore, it is not required for small network services for the time being; in addition, it is similar to Nginx/LVS/HAProxy's Linux-based open-source free server load balancer software, which is implemented at the software level, so the cost is very low. Currently, the website architecture is generally reasonable and popular: the Web front-end uses Nginx/HAPro

CentOS by default) Program code working on the netfilterINPUT hook on the kernel; its cluster function depends on the Cluster Server rules defined by ipvsadm; Supports a wide range of services based on TCP, UDP, SCTP, AH, EST, AH_EST, and other protocols; 4. Key points for timing in a server Load balancer cluster: (1) session persistence Session sticky (iphash): IP Address binding. The source ip address r

Not long ago I was in charge of a well-known national manufacturing group's load balancing project. I was deeply touched by the project's application of gslb in a specific environment and learned a lot of related Load Balancing knowledge. Today, let's calm down and think about how to learn a lot through the project. during the project implementation process, we have encountered quite a number of problems. N

: This article mainly introduces apache and nginx server load balancer configurations. For more information about PHP Tutorial, see. I. apache server load balancer is actually very powerful in operating apache. Recently, I have studied apache reverse proxy and server load

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

Support for the vast majority of TCP and UDP protocolsFlexibility: No modifications to the client and server are requiredPerformance: supports millions of concurrent connections with maximum throughput of the system close to 10GBITS/SReliability: Already used in many large, critical sitesSoftware License: Based on GPL license releaseLVS Cluster system has been formally used in dozens of sites in the United States, Bri

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

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

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

When it comes to the Web cluster, we can't help but say that LVs is a very good open source software for load cluster, compared with some hardware load, LVS has many excellent performance, such as cheap, stable, support high concurrency scenarios in most cases, below to tell you about the origin of LVS and basic introductionI. The concept of LVSLVS is the abbreviation for Linux virtual server, which is the

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.
