I hear you, and I'm passionate about automating all the things. I just wanted to add some perspective to the discussion to set expectations for less experienced people who might be considering a switch from PaaS to DIY.

I'm not a PaaS user, and I encourage people to avoid vendor lock-in and be in control of their own destiny. It takes work though, and you need to sweat the details if you care about reliability and security, which continue to be problem areas for more DIY solutions.

If people aren't willing to put in the work, I'd rather they stick to the managed services so they don't contribute to eroding the already abysmal trust of the industry at large.
