As a consumer, I essentially get to treat it as such - there is no server I need to manage.
In AWS-land this is a big differentiator over a system I have to manage, such as EC2, that just executes containers (meeting FAAS). Now I have FAAS and I don’t have to manage the infra, which is huge because AWS will be far better at meeting a patching SLA than I will be.
Yes, obviously there is a “server”, but I don’t have to think about it.
