Network Load Balancing Configuration OverviewNetwork load balancing is a network driver for Windows 2000. Its operations are transparent to TCP/IP network stacks.
To ensure optimal network performance, network load balancing usually uses a network adapter to handle customer-to-cluster traffic, while other netwo
The server Load balancer described in this article is used to balance client requests among multiple nginx processes. Note the difference between Server Load balancer and client requests on multiple backend servers.

For example, for mailbox applications, the content provided by such services cannot be static and can only be optimized through regional deployment and load balancing.For the vendors that provide cdn services, static content cdn is naturally no problem.

Nginx can be used not only as a powerful web server, but also as a reverse proxy server. nginx can also implement dynamic and static page separation according to scheduling rules, server Load balancer can be performed on backend servers in multiple ways, such as round robin, IP hash, URL hash, and weight. Health Check of backend servers is also supported.
If there is only one server and the server goes down
Server Load balancer in ASP. NET sites: Based on the HTTP protocol, we may find that we need to solve two problems: first, to achieve Server Load balancer, we need a Server Load balancer. You can use DNS round robin to obtain diff

Apache Load BalancerApache can also achieve load balancing. The load balancing of Apache is mainly mod_proxy_balancer achieved by implementation. So, what is the configuration method for Apache load Balancing?In the Apache configuration file, httpd.conf addProxyPass / balancer
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

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.
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
Compare mainstream Server Load balancer instances, such as lvs, f5, nginx, and haproxy! -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Today, most websites use Server Load balancer and reverse proxy software, which usually does not allow the web to dir
according to certain algorithms, balance the load of all servers in the cluster as much as possible. For external clients, they do not know which server in the cluster is accessed. multiple servers can be regarded as a "large" server logically. In this way, when the service capabilities of the cluster cannot meet the current needs, it is very convenient to add new servers to the cluster to meet the needs.
Since we have configured Two CAS servers, it is very easy to configure Server Load balancer in exchange 2013 to enable these two servers to provide Server Load balancer services, without the concept of CAS array, Server Load balancer
