- user5994461 10y agoThat sounds perfectly reasonable. Rules of thumb: If a business has to operate 24/7 worldwide (and maybe even have office in multiple locations), it's gonna need over 100 employees. There is no sane way around that. You don't want to be in a business with less than that many, trust me ;)
- gaius 10y agoIf you need 1 engineer available 24/7, you need 3 teams of 3, one each in APAC, AMER and EMEA, at minimum. You can't sustain running with less, otherwise people can't ever take vacations or get sick... if you need 2 you need at least 12 and so on.
- ci5er 10y agoI know it's pushing it, but couldn't one go w/ 1 team of 5 (probably 6 for minimal downtime/buffer?) in NA to cover 24/7?
- Tushon 10y agoMaking people operate against circadian rhythm is a hard sell. Google advocates against that in SRE book.
- ci5er 10y agoAh. I did not know that. When I was growing up, there was a 24/7 coal-mine near-by and everyone was on two-week rotations for their shift. Which (naturally) sucked. Eternal jet-lag. I thought that letting people simple pick their preferred, and stick to it would solve the suckiness...
- crdb 10y agoI once visited a Ford factory in England where the manager told us the night shift workers were paid very well (more than London front office in their first two years at Goldman Sachs) because their life expectancy might be shortened by as much as 20 years.
- peterwwillis 10y agoApparently you have never worked in a NOC? You need one team of three for 24/7 NOC coverage, even for a worldwide customer base. Preferably four or more but three will do for a while. Tickets are automatically generated from alerts for anything from unusual web server logs to disks filling up to network bandwidth spikes to slow SQL queries, etc. The NOC staffer attempts to resolve problems on their own, and identifies and calls the first point of contact for specific issues as necessary, following the appropriate escalation procedure. As people get woken up in the middle of the night for their shit breaking, after a few weeks, suddenly regular problems either go away or standard procedures for fixes are documented. In a few months a staff of three can handle 90% or more of the tickets that are automatically generated. We were doing this over 10 years ago with about 2000 servers getting traffic from 2,000 to 150,000 hits per second on Perl web apps. Honestly, nobody does anything efficiently anymore.
- gaius 10y ago3 people who never get sick, never go on vacation or training, who never experience denial of physical access (or who actually live inside the NOC??) Oh, you are talking about people who just phone other people, well you need to include the "other people" in your number.
- peterwwillis 10y agoThe "other people" are just people in your company. They aren't on call, but since they own the thing that's broken they get called, it's standard escalation. Two people on shift per weekday, three on weekends, and a non-NOC staff member works a shift on a weekend so they can cover sick time and vacation people. It's not that hard.
- gaius 10y agoYour people are doing 12-hour shifts every day, and only get sick at weekends?? I call shenanigans.

- johnloeber 10y agoWhatsApp was operating with 650m MAUs, 24/7, and was purchased for $19 billion. How many employees did it have? 55.
- meddlepal 10y agoWhatsApp is not and never was mission critical.
- rakoo 10y agoWe're talking about Tinder, though.
- johnloeber 10y agoI don't understand your comment.

- user5994461 10y agoJust because it's possible doesn't mean it's a good idea ;)

- johnloeber 10y agoThey were acquired for 19 billion dollars, so they were very obviously doing things right. Your condescending snark seems misplaced. Maybe the fact that WhatsApp was colossally successful, more so than nearly any other startup -- this was the largest ever acquisition of a venture-backed company -- should get you to update your priors on what kind of scaling practice is a "good idea" and what isn't.
