Haproxy configuration for Server Load balancer and haproxy configuration for Server Load balancerCommon Open-Source Software load balancers include Nginx, LVS, and Haproxy. Comparison of three major software load balancers (LVS Nginx VS Haproxy)

Nginx Server Load balancer transmits the parameter method to the backend (the backend is also an nginx server), and nginx Server Load balancer
A website uses nginx for load balancing and multiple nginx servers at the backend.

the central server Load balancer, but directly to the customer. Therefore, the central server Load balancer is only responsible for receiving and forwarding requests, and the network load is low.
This hardware implementation method is expensive, but it has different speci

As you can see, traditional Server Load balancer is only a load balancing technology. Currently, in the face of complex network application requirements, the independent Server

This series of related interaction processes may be completed by a connection from the customer to the server multiple times, it may also be that multiple sessions are completed in multiple different connections between the customer and the server. The most typical example is HTTP-based access, A customer may need to click multiple times to com

3-2 ajp13 type Worker attributes:
When ajp13 type worker is working, the ajpv13 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process.
The ajpv13 protocol is significantly different from the ajpv12 protocol:
* Ajpv13 has a richer binary protocol. it uses the frequently used string encoding method to compress the request data.
* Ajpv13 reuses opened sockets and retains these opened sockets to handle future r
Based on the huge network structure, the use of Cluster Server brings a lot of load problems such as traffic. So the relative, load-balanced technology also emerged. Each technology requires product support, so let's now look at one of the F5 load balancers. So first of all, we first introduce the structure of the product function.Many vendors have launched a
