So, still no sysadmin.
Not saying it has to be this way, just saying originally that serverless can save you money.
In fact, we are in the process of moving all our APIs over to AWS Lambda w/ ES and it's going to save us 25-50% of our EC2 costs.
We might be able too do the same since we are re-writing in another language, but without AWS Lambda, we would have never gotten that shot.
