So if you have five processes trying to connect to the internet at the same time, but only one network card, Linux needs to make sure that the right messages are sent to the right websites upstream. And the responses are sent to the right programs downstream. If you're, if how to become a devops engineer you've ever run very computationally intensive tasks on a laptop, you might notice that your browser gets laggy.

But since many providers provide Kubernetes out of the box, you can just assume that if you're using Kubernetes, and containers, you'll get auto scaling if you configure it correctly. Just to illustrate, if you're using Microsoft's as your as your cloud provider, there's resources for auto scaling VMs. If you're using AWS, there's again, resources for VMs and containers. And if you're using Google Cloud, there's resources for VMs and containers. Auto scaling is usually discussed on the timeline of one hour chunks of work. If you took the concept of auto scaling and took it to its limit, you'd get serverless defined resources that are quickly started and use them on the timeline of milliseconds.
