Currently using a hardware load balancer as an Exchange deployment scenario, using a hardware load balancer a good advantage is that the load of the application can be distributed more

from:http://yuhongchun.blog.51cto.com/1604432/697466 Now the trend of Web site development on the use of Network Load balancing with the increase of site size according to different stages to use different technologies:One is the hardware to carry out, the common hardware has more expensive NetScaler, F5, Radware and array and other commercial

the performance bottleneck of the firewall as a site, multiple firewalls are used to achieve load balancing, as shown in the following figure (for details, we will discuss it later ): Next, let's take a look at some Server Load balancer products. Load Balancing products can basically be divided into three

server load balancing. Before introducing Server Load balancer, let's take a look at the process of obtaining a page request and response from the web server. 1Entry to exchange technology Now we will briefly introduce the working principles of layer-2 and layer-3 switching to provide the necessary basic knowledge for understanding the concept of Server

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) I. LVS:1. Strong

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. Encountered a problem, when it is used as SSL sup

Article Title: Server Load balancer technology is used to build a high-load network site. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems and open-source, and other basic categories. The rapid growth of Internet makes multimedia network servers, especially Web servers

can be achieved [2]. In reverse proxy mode, you can apply the optimized load balancing policy to access the idle internal server each time to provide services. However, as the number of concurrent connections increases, the load on the proxy server itself becomes very large, and the reverse proxy server itself becomes a service bottleneck. In the address translation gateway that supports server

Vertical scaling improves the server processing capability from the perspective of a single machine by adding hardware processing capabilities, such as CPU processing capabilities, memory capacity, and disks, it cannot meet the needs of large distributed systems (webs

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load balancing system will stop

access external networks, when a computer in an external network accesses an external address owned by the address translation gateway, the address translation gateway can forward it to a mapped internal address. Therefore, if the address translation gateway can evenly convert each connection to a different internal server address, then the computers in the external network will communicate with the server on the address they have obtained, this achieves lo
