One, load balancing load Balance: built on the existing network structure, it provides an inexpensive and effective way to extend the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability. This means that it can be shared across multiple operating units, such as Web servers, FTP servers, enterprise critic
Nginx Server Load balancer dual-host High Availability
If the Web server cluster is used as a city pool, the load balancing server is equivalent to the city gate, and its importance is self-evident. If the "City Gate" is closed, the access to the outside world will be broken. If a server is balanced, when the server fails, the whole website will be inaccessible.
Hi, today we will learn how to use Weave and Docker to build an Nginx reverse proxy/Load balancer server. Weave can create a virtual network that connects Docker containers to each other, enabling cross-host deployment and Autodiscover. It allows us to focus more on the development of the application rather than on the infrastructure. Weave provides such a great environment as if all its containers belong t
Nginx reverse proxy and Server Load balancer
I. Introduction
Reverse Proxy(Reverse Proxy) means to use a Proxy server to accept connection requests on the internet, and then forward the requests to the server on the internal network, return the result obtained from the server to the Client Requesting connection from the internet. The proxy server is displayed as a server.
Reverse Proxy
instances on two different physical hosts.
Use case: Make sure that each member in the HA group is configured on a different virtual Machine Manager (physical host).

Let's pause for a moment and take a look at the symbols and conventions used in this article, as well as some considerations for setting up the environment.
Commands executed as root on the system are prefixed with root@host#.
Use the user@host# sudo as root on the system to prefix with the sudo execution command.

I. LVS (Linux Virtual Server)
LVS is short for Linux Virtual Server. It is a Virtual Server cluster system. LVS operates on the fourth layer of the ISO model because it operates on the fourth layer, therefore, like iptables, it must work in kernel space. Therefore, like iptables, lvs directly wor
In the past, running a large web application meant running a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the 'large server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs.
The 'more servers' mode has more advantages than the
F5 is a well-known Server Load balancer product. I believe many people will not know it. So how does it maintain sessions? Let's start with the definition of session persistence. As an image metaphor: Session persistence can be seen as a string of pearls, so we split each Pearl and put it in a different box for storage and then put it into a string, that is, the concept of allocation. So how do we describe

Because the project has encountered a large number of image storage problems, although we still have a lot of images (currently up or down 1 TB, it is estimated that the growth rate is 1.3 times per year ), when I think about how to effectively store a large number of

The company has developed a website. The estimated maximum number of online users is 30 thousand, and the maximum number of concurrent users is 100. Whether or not the developed website can withstand this pressure and how to ensure that the load of the website is no problem, after research, it is decided as follows:

Server Load balancer is a technology that implements Load Balancing through an algorithm. In layman's terms, requests are uniformly distributed to devices,Server Load balancer will receive all requests in a unified manner, and then distribute these requests to the server
Today, the 'large Server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs.
The 'more servers' mode has more advantages than the 'large Server' mode in the past. It is reflected in two aspects:
1. If the server goes down, the Server Load balan

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
