What is a distributed application architecture?
In this section, we are going to explain in detail what we mean when we talk about a distributed application architecture. First, we need to make sure that all words or acronyms we use have a meaning and that we are all talking the same language.

Normally, a node is part of a cluster. |
Cluster | Group of nodes connected by a network used to run distributed applications... |
