Cluster
A group of computers working together as one system
What's it for?
Lets several computers share work so one machine failing does not necessarily stop the whole service.
For example…
Three servers run the website so one can fail without stopping it
A database cluster spreads data across several machines so service can continue if one node fails.
Think of it like…
Restaurant kitchen with several cooks: if one steps out, the others keep the orders moving
