As someone who’s set up and managed critical business applications I would say that it’s perfectly fine to host your own provided you have decent hardware that’s capable of doing what you need and as a dedicated business line to provide connection.

If you try to run mission critical business applications on a home internet connection you’re going to have a really bad fucking time. But hosting business critical applications on appropriate hardware and a 1Gb/s business connection with an SLA is going to meet 95-98%% of all business applications.

If something like that sounds expensive or too difficult to do then it’s too expensive or too difficult for you to host yourself. Just go with a provider and sidestep self-host.

Debian, baby.

Chest freezers are exceptionally energy efficient. It’s not a very good comparison.

You’re completely missing what he’s saying, and how that number is calculated. It’s an average connection speed over time and you’re anecdotally saying your internet is superior because you have a higher connection speed, which isn’t really true at all.

You have residential internet which is able to provide 3Gbps intermittently. You may even be able to sustain those speeds for several days at a time. But servers maintain those connections for months and years at a time…

800TB/mo is 2.469 Gb/s sustained for 30 days. They may be on a 10Gb/s connection, but that doesn’t mean they have enough demand to saturate it 100% of the time.
