I work in AWS’s Serverless group, and in the process of pulling together my presentation at re:Invent, discovered that I have a lot of opinions on the subject and, while they may well be wrong, are at least well-informed. You can watch that YouTube, but who’s got an hour to spare? And anyhow, blogging’s really my favorite medium, so here we go. If I tried to glom them all together into one mega-essay it’d be brutally long, so let’s go short-form.
The Serverless Fragments · “Serverless Fragment” has five syllables and ongoing doesn’t have that much room at the top of the page for the title, so let’s say “SF”.
SF 1: What is serverless? Tl;dr: It’s when you don’t have to reserve capacity before you start. But it’s not a binary condition.
SF 2: Why serverless? Tl;dr: Frugality, Security, Elasticity. That part’s a no-brainer, but will you also get better software?
SF 3: Serverless everything? Tl;dr: Nope, serverless where possible. To start with, think about control planes and data planes.
SF 4: Serverless latency? Tl;dr: It’s complicated. And, there are things to do about it.
SF 5: Serverless bills? Tl;dr: Not always lower. But it depends how you count it.

Things change. Received wisdom becomes the foolish muttering of old men made obsolete and then scorned. True of science, art and politics.

Serverless is when there is no server - only clients and P2p connections. Stop Amazon propaganda :))
