> HN is usually a pretty good gauge for how the wider engineering community feels about a particular technology.

....no, no it really isn't. HN is a bit of an echo chamber of people who care about being on the cutting edge. 80% of the rest of the industry goes home and stops thinking about software engineering.

Anyway, here's my two cents: I'm building a web app that has the following components:

* A super simple SPA frontend

* Like...5 API endpoints? that allow people to register their emails to the service

* A mailer that sends out a daily email at the time the user specified

* Like 5 more API endpoints for manipulating some per-user data (profile, preferences, etc).

For this use case, serverless is _perfect_. I'm using the "Serverless framework" which allows you to write the definitions for your functions (think routing rules, a la `routes.py` in a Django app) and CloudFormation directly into a YAML file, then it consumes that, updates a CloudFormation stack with all your bits n' bobs all connected together, and gives me:

* 10 or so lambdas

* Monitoring for all of the above, including pings if something goes catastrophically wrong

* A DynamoDB table to hold all the data

* An API gateway hooked up to all the lambdas

* An S3 bucket with my static assets in it

* A CloudFront distro set up to CDN all my static assets

* A DNS record to hook up CloudFront to my URL

* An SMS (emailer from AWS) queue to ship out emails on an hourly or so basis

This whole stack is declared and managed with like 120 lines of YAML and deploys itself in a minute or two, no extra automation or management required. It costs me like 2 dollars a month right now since I haven't launched the site, but by my back of the napkin calculations, it'll probably cost under 50 bucks a month with my expected traffic. Serverless can be great for this sort of thing, and if I do eventually need to migrate this to VMs running containers or something it won't be _that_ hard (it is, after all, just a pile of TypeScript running on Node).

Now, I'll be honest, it took me a full day of tinkering to figure out how to get static assets in an S3 bucket to publish to CloudFront, but that's because I don't read docs very well, and now I know how to do it for the future. I imagine if I had less hubris and found someone else's tutorial for doing so, I could have had it solved in an hour or so. But lambda does work for a lot of simple use cases.

I imagine that most peoples' shitty wordpress sites from 2006 would benefit a lot from being frozen into static HTML, dumped in an S3 bucket, and put on a CDN. They'd get security patches, OS updates, a global CDN and a bunch of other goodies essentially for free. And the sad reality of our industry is that most of it isn't building fantastically intricate real time distributed systems that both cook your breakfast and brush your teeth, it's maintaining some guy's shitty wordpress site from 2006. Tech isn't sexy outside of the FAANG/HN bubble, and _that's perfectly OK_. Serverless is a great paradigm for those people that don't need anything fancy, it's like the modern LAMP stack IMO. It's a good enough default from a performance and cost perspective for most people who have no business thinking about (or who just really don't want to think too hard about) their infrastructure.

Is it a pile of bespoke garbage that sometimes feels like it's going to topple over? Sure, but so does all the software I work on at my day job. At the end of the day, people should use whatever is right for the task, and serverless is great for low- to medium-volume mostly static sites and apps that have a little bit of data manipulation and a little bit of background processing but nothing that rises to the level of _needing_ to manage your own infrastructure. And that does really cover a significant portion of the industry, even if it's not being adopted by the 80% right now.
