This is fine if three nines of availability is all you need. Doesn't matter much if you prefer a big brand employee fixing things or a small brand employee. It doesn't change the outcome.
However there are a lot of things that simply cannot live with crappy three nines availability. And the only way to do better is to stop relying on any single cloud, which inevitably requires infrastructure engineers aka random devops dudes.
They will change career after being forced to work on week ends and holidays a few times. Incidentally, today is a Sunday AND the most taken holiday of the year.
The ones who are the single "random DevOps dude" at a small company trying to emulate AWS and Google, do have zero balance.
Why would you do anything else for your sysop/sysadmin?
You need at least 10 sysop/sysadmin to achieve anything close to that SLA, with a sustainable rota. Contrary to the parent posters who believe it can be done with THE right guy.
And keep in mind, 20 minute response doesn't mean you fix the problem in 20 minutes, it means you respond in 20 minutes to the callout.
I think you're victim of an easy-going startup culture.
I’ve been oncall for escalations for like 15 years. That’s miserable enough, IMO frontline guys need fixed schedules and rotation if the volume is high.
I definitely cast my perspective on this and apologize if I came on too strong,
Hiring some dude won't give you that.
Please wait until Monday 20th to get a status on the issue. Thank you.
