 So one of the benefits of airline is that it was actually invented to solve a particular problem and the problem happens to be that of your scalable reliable systems and So yeah, I think the key feature and the secret source to that is the concurrency model So airlines concurrency model is based on immutability Which is a feature which has existed in functional programming languages since they won. It's been in there forever And and the fact that process is you can only mutate their own data other processes can't mutate another process data so yeah, the based on the notion of mutability then you have processes which don't share memory and That means that you know, you can locate processes on separate machines and that by default gives you full tolerance because You know running on two separate machines If you lose one machine you copy state to the other the other machine can take over but not only When you've you know when you've got two machines you also have scalability because you have twice as much computing power So it's a very very simple concept But which actually you know is a secret source to scale scalability and reliability and that's something which yeah We've not really seen in other a functional programming languages out there Which are not running on the beam
