To me DevOps means a shift of the traditional responsibilities of System Administrators to Software Engineers. Either Software Engineers take on all those responsibilities replacing Sysadmins or Sysadmins become programmers in order to be able to design and implement software which does what they used to do.
The point is that the Designer of the Software, now has full responsibility right through deployment and continuing while the software operates in production. This means that you can no longer fob off these responsibilities on other people and say that you are "just" a full-stack developer. It means that you must understand how your code makes use of computer hardware and virtualization systems, and design something that can reliably and smoothly be deployed into production (changes) and operated ongoing (monitoring, health boosts, etc).
AWS is just one of the ways in which code can be used to provision hardware and deploy code.
Google has a role called SRE which is really the heart of DevOps. They HAVE TO do this due to scale, but even smaller organizations should learn from Google SRE best practices because this is the future of ALL computing.
In fact, it is already at the point where software engineers who have never handled hardware (IOT, Raspberry Pi, Micro:Bit) are obsolete even if you are just graduating from college in June.
Multicore CPUs with multiple cache levels, shared RAM, control over which cores are active and how fast they run. GPUs. The Von Neuman model of a computer is long past.
Today there is a new definition of computer. It is a network of processing units, storage units, and communication links which can be made to work together to do useful work.
Note that this definition includes a single 4-core Intel i7 chip, and all of AWS. Distributed computing is no longer something that happens between your computers, it also happens inside them.
