I worked in a advertising network company which is a major player of one city. I re-write the ad-serving algorithm to solve some of the problems. That piece of code is running 24/7 for 5+ years. If you are in that city and browsing the web. It will run through my code path.

I think Manta is better if the result set is smaller than input set. So network performance won't matter that much. And also a per second pricing is better since the author need the result in 10 seconds.

Spinning up a cluster of VMs and use 10 seconds and they charge you min. 1 hour seems expensive to me.

I work in AdTech too. I'm still looking for a perfect counter solution. The counter we are using always overrun (which is better than up/down/up/down). We still manage to hack it by patching the number periodically.

p.s. I am working in an Ad Network but not plugging into exchange. Our system is not capable for that.

Atom has a 2MB file limitation. That's why I wouldn't use it professionally yet.
