It can handle high load pressure and stability. In the case of poor hardware, it can support tens of thousands of concurrent requests, and the load is relatively sm

You only need to configure the Intranet IP addresses, but their default gateways must be the content IP addresses of the scheduling server. In this way, when the user requests the data packet, it modifies the data packet and changes the target address to the actual IP address of the internal network processing servic

Recently, when using Microsoft cloud, we found that azure launched the standard version of Server Load balancer, which should be good news for many users with high security requirements, you can configure SNAT. With azure Server Load balancer, you can:

Reverse proxy Load Balancer ApacheOne, reverse proxy1.1 Introduction Reaction AgentThe reverse proxy method refers to a proxy server that accepts connection requests on the Internet, then forwards the request to a server on the internal network and returns the results from the server to the client requesting the connection on the Internet, Reverse. At this point the proxy server appears as a reverse proxy s

Server B processing page Server C processing page What if one of the servers goes down?When a server goes down, will access be affected? Let's take a look at the instance. Based on the above example, assume that the host of the C server 192.168.5.126 is down (because it cannot simulate the crash, I will shut down the C server) and then visit it. Access results: We fou

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check.
