Really? I have to say I don't understand it. I remember the "NoOps" movement from a few years ago and I just find the whole concept around it to be almost hilarious; kind of like Salesforce's old "No Software" logo (which is nowhere to be found in their newer marketing).
As I see it, as long as your organization has people using IT in any capacity at all, you will need someone in charge of IT Operations. Whatever you may want to call it: DevOps, or SRE, or PE, or even if you just decide it's something that each of your regular devs is going to be doing, it's a function that needs to be done.
Someone needs to be able to set up the systems, monitor them, scale them, secure them, and troubleshoot issues. It doesn't matter how well-engineered and maintained and automated the components you rely on are, they will break in various compound fractures and you will need to deal with the downtime and potential corruption to your composite system.
I'll eat my hat if you can point me towards a single non-trivial software service that has been running continuously without any "IT".
That's true, but I don't need to worry about the server that my database, load balancer, queuing system, RedisCache, storage, etc. is running on. I only have to worry about my applications and the actual database. If I need to provision more hardware, it's a click of a button (well actually updating my CloudFormation template).
There is an entire level of both hardware and operating system maintenance that I don't have to worry about.
Right. So you traded [relatively] inexpensive OS and infrastructure maintainers for [relatively] expensive application and tier maintainers.
This is certainly part of the reasoning for things like terraform, cloudformation, even chef/puppet/ansible—people want a single process for development of reviewing and executing code.
I always pronounced that as "nnnn..oops"
They definitely don't offer anywhere near as many services as Google, MS, Amazon, or even Alibaba's cloud offerings. But they're becoming pretty decent 'cloud lite' providers who cover what's needed for plenty of folks and companies.
Might want to go recheck the API documentation for providers like DO et al
