Can someone explain what DevOps is

Question

could someone please explain to me what DevOps and Cloud Computing are without using all the buzzwords?

I tried my best to define DevOps by searching for it on Google, but the buzzwords in every description or definition prevented me from doing so. In essence, ELI5?

I thought I'd provide an illustration of some of the overused definitions I saw. This is the FAQ's exact response from Amazon. Describe DevOps:

"The combination of cultural philosophies, practices, and tools known as DevOps improves an organization's capacity to deliver applications and services at high velocity: products evolve and improve more quickly than they would in organisations using conventional software development and infrastructure management processes. Organizations are able to provide better customer service and engage in more profitable market competition thanks to this speed."

I mean...seriously?
