This is what happens when developers want to do sysadmin. Come on guys, we, sysadmin, spent as much time learning our job as your learned coding. If we would be trying to code, we would be lost and pissed off. That's why we don't do it.

The OS is not wrong, what is wrong is you imagining that every system should be as simple as "right click / start". If you want that, take the Heroku/<you PaaS here> route and you'll be happy. But the day you have 5000 customers connecting at the same second and your environment collapses because you don't have the flexibility to tune it, don't come crying.
