In a startup you may not have the luxury of affording both devs and ops. Most of the time you end up having a devops guy who does a lot of both. Compilers are the same regardless of who's using them, but ops needs to be tailored for specific use-cases, which is very different.

Just like how a 3-in-one printer/scanner/fax machine does none of those jobs well in comparison to separate dedicated devices, you get what you pay for.

No, rolling out code, and seeing it run in production makes developers more responsible. Having developers write their own code doesn't do the same thing.
