WhatsApp passes 800,000,000 active users

TechCrunch is reporting on WhatsApp passing the 800,000,000 active users mark.  Almost exactly a year ago, it was at 500 million active users.  I don’t care much about WhatsApp’s business or service, but from the technical point of view this is quite significant.  That’s almost a million active users acquired every day for the last year.  That’d be a challenge for anyone to handle.  Thinking that this growth might have been not too linear gives me digital goose bumps.

I haven’t seen anything recent describing their infrastructure, but this article from last year provides a starting point for the imagination:  Erland + FreeBSD + 550 servers, with preference for larger box with loads of RAM and cores.  I’m sure that have grown quite a bit in a year too.
