Useful, cool tool and a nice site
From 3 comments
serverless is the shake weight of tech. in all seriousness a very useful and cool tool. thanks for sharing! i'd have picked a more informative domain; maybe serverless.info? nice…
upbeatlinux on HNWonderful website! Really appreciate the detail put into this. And it worked very smoothly on mobile. Indeed, lambdas are worth considering for some but not all projects, and…
keyboardhitter on HNThis is great, I wanted to make something like this once but never got round to it. Mainly because the pricing calculator from AWS is pure trash

Objections
Lambda high tail latency and cold starts
From 2 comments
What it doesn't mention is the high latency of the 99th percentile of requests. If that's something that you don't want, then avoid Lambda, for now.
SideburnsOfDoom on HNPerhaps you could factor in something about cold-start? I know that in my context, this has been a key issue. Another odd one is that our organization has only certified RHEL and…

No price cap against runaway bills
From 1 comment
The thing that makes me nervous about Lambda is the lack of price capping to prevent buggy functions racking up thousands of dollars in a weekend.

Calculator ignores hours of use and cold start
From 2 comments
Nice calculator, but it's missing an important field: How many hours per day do you keep your machines running. It assumes you run 24/7. S3stat's nightly job needs 60 or 70 hours…

Add background explaining Lambda on the landing page
From 2 comments
I'm sure it's quite obvious to those who work intimately with Amazon services, but for the rest of us, and because it's un-googlable, this apparently is referring to a specific…
ghostly_s on HNPoint well taken, we'll iterate on this and add some background on Lambda.

Make inputs editable to get new results
From 2 comments
Fun site! It's a bit annoying that you can't edit the input and get a new result though.
stephen123 on HNThanks for the feedback! You should be able to edit the inputs by clicking on the left hand side (application name) to change the inputs above.

Questions
Is the requests-per-minute input total or per instance?
From 2 comments
It's unclear if the Requests/minute is per instance or total. I tried putting in 500k/minute (total) and got a $40k Lambda bill vs $2k EC2 bill (which is roughly what we pay). If…
fastest963 on HNIt's the total number, sorry for that not being clear. We will make some improvements that may help clear that up.

Alternatives named
OpenFaaS
From 2 comments
This is a very neat project. For those folks where this doesn't quite fit and you want the serverless experience checkout OpenFaaS and our PHP template too -…
alexellisuk on HNNo, but take a look at OpenFaaS or FaaS-netes, similar concept but running on-premises. Definitely less mature, but they can get you 90% of the way there if you're not doing…
