Introduction to load Balancing clusters Main open source software LVs, keepalived, Haproxy, Nginx, etc. The LVS belong to 4 layer (network OSI 7 layer model), Nginx belongs to 7 layer, Haproxy can be considered as 4 layer, can also be used as 7 layer The Keepalived load balancing function is actually the LVS LVS This 4-tier

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

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.

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

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
