I used nginx to implement the website load balancing test. In windows, IIS performs load measurement. If your website traffic (pv) is getting higher and higher, and one server is no longer able to withstand the traffic pressure, increase the number of WEB servers for load. Website load can be achieved by buying

In "high concurrency, massive data, distributed, nosql, cloud computing ...... I believe many of my friends have heard of and even often talked about "clusters and Server Load balancer". But not all of them have the opportunity to really come into use these technologies, not everyone really understands these technical terms. The following is a brief explanation. Cluster) A cluster is a loosely coupled mult

Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind has the reverse proxy function software.

, there are also real-time static content, the Mop-like hodgedge and Netease community use such strategies.Category 3: The content changes in real time and is very personalized. 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.
