What DevOps do? This is a good question, no one dares to admit that she doesn't know
What is IT infrastructure? The nicest explanation I learned from Otter Networks The physical and organisational structures and facilities (e.g. buildings, roads, schools and hospitals ) needed for the existence of a society or enterprise. In IT we can consider anything in a computer system that is not the application infrastructure.

NIST cloud computing  definition  NIST (The National Institute of Standards and Technology)  cloud definition expanded over the years to  two pages. I just quote the beginning here:Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and re…
