So this is different from running docker containers on heroku because heroku has 1 to n autoscaling but not 0 to n? What are the other fundamental differences?
It's actually pretty similar to the Heroku free tier dyno "sleep" till there's a trigger, but it's stateless. Different pricing, different ways of conceptualizing but from a user perspective that's a pretty good comparison.
Can we use "stateless" instead of "severless"? That seems like a better term.

Which usually have very low time restrictions in the order of a few minutes.
Break your operation into a series of discreet tasks. For 99% of use cases, if you have an discreet task that takes 5+ minutes, there's a problem. In most cases, it can be split up.
"Serverless" So where do your functions execute?
I think “serverless” doesn't actually mean no server (a distributed system, like Dat); it means “don't worry about the server; we'll take care of it for you”. …or maybe that's “Cloud”. Is there a clear explanation of what “serverless” means, and how it's different from “Cloud”, suitable for semi-technical non-developers?

Serverless is fantastic for ETL and data analysis, especially for workloads that vary in scale (eg cronjobs). Feed data in, get data out with scaling as needed.
but how do you feed data in? Usually, it's some other service on one of the big 3 cloud providers. I'm using google for my projects these days so it's a mix of Google PubSub and Dataflow. I think this is the issue/risk with serverless. You either get locked into one of the big 3, or you end up doing all of the ops work to run your own stateful systems. As some of the people above you said, managing and scaling the st…

And so ZEIT, my favorite serverless provider, keeps getting better. Highlights: - "sub-second cold boot (full round trip) for most workloads" - HTTP/2.0 and websocket support - Tune CPU and memory usage, which means even smoother scaling And all that for any service you can fit in a Docker container - which is also how you get near-perfect dev/prod parity, an often overlooked issue with other serverless deployment te…
I know of 1 large scale web application that is 100% driven by serverless technologies. The user experience (as an end user using the website) is pretty terrible IMO. It often takes multiple seconds for various areas of the site to load (bound by the network). It's also super Javascript heavy and just doesn't feel good even on a fast desktop workstation. Authentication is also a nightmare from a UX point of view. Eve…
In the mid-90’s it was common to run httpd via inetd. That lasted until HTTP 1.1 came along. I see people running websites out of Lambda now and just get a sense of deja vu. We realised this start-on-demand style didn’t scale for highly interactive use cases 20+ years ago!

What's a FANG developer?

Why is that? Are you "afraid" that mp4 have some embedded code that will run...idk I just made that up!
.mp4 videos usually use h264 compression (and now h265 for 4K/HDR), which is not free or open source. .webm uses VP8 or VP9.
Specifically, to be covered you have to download a binary release from https://github.com/cisco/openh264/releases during the installation to be covered by Cisco's MPEG LA patent license, but they provide builds for most major platforms.

why both? Android can do mp4, no?
WebM (or rather, VP8) uses less bandwidth and has better quality.
