: When talking about web servers, what is a « cluster » ?
In: Technology
Clustered web hosting is when instead of having just one web server providing the service you have multiple physical machines sharing responsibility for the load. This both ensures your website can handle more requests at once and prevents services taking resources away from each other, but also makes sure that even if a computer goes down the website as a whole still stands strong.
Imagine you have 4 computers or nodes serving your website. There might be a fifth computer sitting in front acting as a load balancer: it will grab all the requests coming in, and try to evenly spread them across the 4 computers so that none of them get overloaded and the website can have more clients served at once.
