When I was at a company that went all in on AWS. I went from 100% of time working on product, to easy 75% of time working on AWS. Even though we had teams who just set up infra on aws for us to use and it was supposed to be "so easy". There was far more time setting up AWS infra than writing code.
Yes, and management discounts that .. if you make me, a product expert, working on application software.. deal with this stuff, I am going to do the worst, most rapid, half-assed, security and everything else be damned job.
I have clients, product, scrum masters, tech leads, and others breathing down my neck on feature delivery, and you're asking me to figure this alphabet soup out, lol.. don't expect happy results dudes.
I've been a domain expert in a field for 20 years, what value do I bring to the client in dealing with this alphabet soup of AWS networking/security? Either it works and client gets what they want, or it doesn't and they don't.
This stuff is a full time job and should be respected as such. If you think you can push it all down on app dev, you are going to have unhappy results.
