The art of building, operating, and running distributed systems in industry is orthogonal to the theory of Distributed Systems. Let's get a little more specific about the types of failures that can occur in a distributed system: One reason for this is the difficulty programmers have in obtaining a coherent and comprehensive view of the interactions of concurrent processes. The machines that are a part of a distributed system may be computers, physical servers, virtual machines, containers, or any other node that can connect to the network, have local memory, and communicate by passing messages.
