Finally it's time for changelogging friends With Adam and Jared and some other rando We hope that you love it and stay until the end We're not offended if you can't go We know you're probably busy coding And your deadline is pretty foreboding Your caffeine intake is an actual problem, so why don't we walk outside? And we can listen to Change Logging Friends with Adam and Jared in Silicon Valley. We know one day the gag will come to an end, but honestly, that will probably be our finale. We bet you sling A1s and 0s And that makes you one of our heroes Your list of to-do's will be waiting for you So why don't we walk outside And we can listen to Change Logging Friends With Adam and Jerry and people you know Change Logging Friends Let's get back into the flow Change Logging Friends Change Logging Friends It's your favorite ever show Favorite ever show
Welcome to Changelog and Friends, a weekly talk show all about that bass. Special thanks to our partners at Fly.io, the public cloud built for devs who ship. Deploy your app in five minutes or less at Fly.io. Okay, let's talk.
What's up, nerds? I'm here with Kurt Mackey, co-founder and CEO of Fly. You know we love Fly. So, Kurt, I want to talk to you about the magic of the cloud. You have thoughts on this, right?
Right. I think it's valuable to understand the magic behind a cloud because you can build better features for users, basically, if you understand that. You can do a lot of stuff, particularly now that people are doing LLM stuff. But you can do a lot of stuff if you get that and can be creative with it.
So when you say clouds aren't magic because you're building a public cloud for developers and you go on to explain exactly how it works, what does that mean to you?
In some ways, it means these all came from somewhere. Like there was a simpler time before clouds where we'd get a server at Rackshack and we'd SSH or Telnet into it even and put files somewhere. and run the web servers ourselves to serve them up to users. Clouds are not magic on top of that. They're just more complicated ways of doing those same things in a way that meets the needs of a lot of people instead of just one. One of the things I think that people miss out on, and a lot of this is actually because AWS and GCP have created such big black box abstractions. Lambda is really black boxy. You can't pick apart Lambda and see how it works from the outside. You have to sort of just use what's there. But the reality is like Lambda is not all that complicated. It's just a modern way to launch little VMs and serve some requests from them and let them like kind of pause and resume and free up like physical compute time. The interesting thing about understanding how clouds work is it lets you build kind of features for your users you never would expect it.
And our canonical version of this for us is that like when we looked at how we wanted to isolate user code, we decided to just expose this machines concept, which is a much lower level abstraction of Lambda that you could use to build Lambda on top of. And what machines are is just these VMs. that are designed to start really fast or designed to stop and then restart really fast or designed to suspend sort of like your laptop does when it closes and resume really fast when you tell them to. And what we found is that giving people those primitive is actually there's like new apps being built that couldn't be built before. Specifically because we went so low level and made such a minimal abstraction on top of generally like Linux kernel features. A lot of our platform is actually just exposing a nice UX around Linux kernel features, which I think is kind of interesting. But like you still need to understand what they're doing to get the most use out of them.
Very cool. Okay, so experience the magic of Fly and get told the secrets of Fly because that's what they want you to do. They want to share all the secrets behind the magic of the Fly cloud, the cloud for productive developers, the cloud for developers who ship. Learn more and get started for free at fly.io.
