This is a potentially stupid question, but I'm a little bit high and I'm confused. How exactly does a server get spun up?

So if I'm writing a node server file on my local computer, I spin it up by allowing my local host port 3000 (or frankly whatever I choose) and creating a "listening" state.However, when you host servers online, where exactly do you host them? This may be a really stupid question, but when you upload your server code to an EC2 instance on AWS for example, is that considered a server because the code will run and live on there forever, always being open? And the only way to reach that code is via APIs that code serves, right? Like, what if you hosted on GoDaddy and had your own series of subdomains. Can you consider those subdomains servers if you deployed some kind of VM and ran the code from that VM which served directly to those subdomains?Also, what are LAMBDA functions? Are they like anonymous functions or something in Javascript? I never quite got the grasp of what they were.I'm [8/10]🥦 right now, uhh.
