serverless supervisor
in charge of making sure the serverless environment is in fact, serverless
occasionally have to check if it's really serverless
one day, find out there are actual servers being used
serverless environment is no longer serverless

ask my boss what to do
he says "just make it serverless again"
I say "how"
he says "I don't know, you're the supervisor"

quit my job
become a servers supervisor
first day on the job, go to the new server room
it's empty, serverless
Serverless usually means that the servers are 'hidden' from the user. You only get one shell, one desktop environment, but on the backend, your session might be split between multiple servers. Or it might not be. You, as the user, won't know. It is basically an abstraction layer between you and the servers themselves.
To add, it is typically manifested as generic 'compute' or in the case of azure 'functions' where you environment the code is running on is abstracted away, instead you are just paying for compute, e.g. this function takes x time/cycles to run and so it costs y to run it each time.
In theory you don't need to worry about scale or anything, just deploy your function, and pay for what it uses.
Surely this will never come back to bite me
Yeah better get really good at paying unexpectedly high invoices. Or if you want to know ahead of time what your costs will be, hire three specialists who will monitor your not servers as their full time job and make sure your „functions“ are not bankrupting you in a month. If you think you sleep too well, go serverless you’ll never sleep well again.
One Riker, one bridge!
