Servers running javascript are called "a dumb idea". But that's neither here nor there - The core idea of "Serverless" is that you don't have stateful physical machines that you manage, only a series of processes - which can live just about anywhere, with only clearly defined interfaces to shared state.

So, a server with an API. Gotcha.

Edit: downvotes? how is what he is describing any different to that and anything else other than a buzzword? Doesn't AWS Lambda just run your processes in an ec2 instance?

Yes but you don't pay for the hardware specifically, eg. Your code doesn't care when underlying lambda hardware fails because it's not contained within any specific server. You pay for the invocation costs which are usually much lower than running a server to do the job as you're gaining economies of scale with other tenants.
