Reliability: It’s not great

At first I was all like “Ha ha, losers can’t scale”

And then I was “Huh, these technical challenges are actually pretty difficult”

And then I was all “crap, these are a bunch of technologies I was about to add to our stack”

Thanks heaps fly.io people; having the humility to honestly talk about the challenges and failures massively helps people such as myself as we navigate new unfamiliar technologies. If more companies were willing to do this, it’d be a lot easier to avoid common pitfalls.

The tech in their stack is still pretty good. Unless you’re supporting tens of thousands of customers and trying to make the promises that fly makes today. Look at the fly engineer replies in this thread.

Also they basically only use OSS versions, they could go give Hashicorp some money to solve their Vault problems. They could probably partner with SecondQuadrant for PG as two examples. That might not make sense for their business though.

Hard problems are hard no matter the choice.
