The Cloud doesn’t remove the need for infrastructure and operations people. Nor does it particularly make infrastructure easier.
It simply shifts where the hardware runs and who owns it.
And for small software teams it still means the developers and project manager are “the” operations and infrastructure people.
The big difference now is The Cloud makes it much easier to accidentally spend vast amounts of money on infrastructure you had no idea you deployed (or who deployed it), where you struggle to understand what it does or why you need it, and you can never seem to figure out how it is charged on your bill.
I know this because I live it.
