I did get the thanks for applying but we are not looking at you at this time response, I don't want to sound too entitled as I know you get a lot of candidates but it seemed very short and wondered if something big like not being based in Ireland was a straight up decline etc

I dont know of any, but I'm not in that team/office so I cant really speak for them

Thanks a lot for your response!!

  1. Damn 100 Garens is a lot. I guess its quiet noisy in your datacenters.

  2. Interesting. I would have thought you have quite a lot more linunx servers.

  3. Ok :)

  4. Really interesting concept. I think that is one of the main differences when everything is scaled up like crazy. However you still need to worry about corrupt data spreading over multiple systems - right?

  5. Sounds interesting. Can you tell something about the management hirarchy you guys are running? Classig team with teamleads or something different?

  6. Ok, no problem.

  7. Office 365

  8. Thanks a lot for that information. Never heard of that software but sounds interesting on the first look. Definitely will have a look at it in more detail tomorrow.

Thanks a ton again and have a great day!

Lots of whirring, its like a URF one for all with both sides picking Garen

Not really, I mean theres obviously a risk, but its pretty low given that most data is pushed too servers, and the only thing that comes back goes through well formed APIs. I dont know that we've had an incident like you describe.

Teams are mostly self organizing, but my part of the world we have a Dev Manager hat that takes care of trying to keep us working on a sustain...

Does that mean that the Delorean has the top let down and the sunshine is shining?

What sort of specifics are you looking for in candidates, especially in first stages? I did recently apply to the engineering team and am a data scientist/coder in London. I was pretty disappointed to not even get to the non automated/HR response given I think I have a pretty strong CV and positive processes with large competitive investment banks etc with same credentials

Like no email no call nothing? If thats the case, I'd say something is probably wrong and you should resubmit.

A bit late to the party. but still worth a shot.

  1. How does your team handle scaling for game servers? Are the servers containerized and are they running on any orchestration platform like Kubernetes? I'm curious if game servers are any different from normal server scaling and if there is any extra thought that has to go into it.

  2. Does your team use any Infrastructure as Code or Configuration as Code practices to version control your backend systems? I've chatted with your build team before about their use of Terraform, but I'm curious if that practice is also shared by your team.

Thanks! Always a blast talking to Rioters about y'alls architecture and engineering :)

  1. Game servers are treated like every other server, just with high network other resource utilization. They differ mainly in that the work loads last between 15 minutes and 4 hours and cant be interrupted with out impacting players. So we try to not do that ever.
    1. We do have orchestrations like docker / k8s /dcos.
  2. Some of use make heavy use of ansible and jinja, others are into Napalm, and we also have a lot of in house built tools to do specific one off tasks.

Glad I could help!

Thanks so much for the response ! I’ve tried most things just wanted to pick your brain for anything I haven’t done yet!

Good luck!

What is ekg.riotgames.com? I have a pi-hole (a dns sinkhole for adverts) and it loves blocking this domain, doesn't seem to impact league at all but it makes me wonder what it is?

Its the client stats reporter end point. That feeds data that allow us to detect problems with ISPs and feeds services like lagreport

Thanks unfortunately wifi is my only option

Theres a lot of options with wifi, a dedicated point to point bridge on a different channel could help. Consider changing between 2.4 and 5ghz, there might be something specific interfering with which ever one you are using. You may try changing channels as well. It might be a crowded airspace. Might consider getting directional antenna, could help a lot there too. I dunno, don't give up there, work the problem, experiment with settings and positions for your wifi.

Probably to get promoted and not be able to code anymore

Sorry for the late response but maybe I can still ask some questions :)

I am working as a System Administrator in a medium sized company so I am really interested in the more basic stuff going on in the background if that makes sense.

  1. Can you tell us anything about how your basic server infrastructure looks like? For example:
  2. How many servers?
  3. How many Windows/Linux/Other servers are there and which versions are you using?
  4. What kind of storages are you guys using and how big is it?
  5. Which backup software are you using?
  6. How specilaized are your "IT guys". For example are there dedicated mail, storage, VM .... teams?
  7. What does your mail infrastructure look like?
  8. Are you doing everything on premise or M365?

  9. What software are you using for asset managing? This is quite hard even for small companies but I think for your this is insane with all the dependencies.

Thank...

Lot of stuff in here, unfortunately we dont really talk specifics when it comes to numbers and versions, I also dont know much about the back office (IT) side of the house so I wont speak for them.

  1. Lots of servers, at least 100 Garens
  2. We have about a 60/40 mix of windows and linux servers, depending on usecase
  3. We use open source front end / middleware on top of whitebox servers with a lot of disk
  4. With few exceptions we treat our servers as cattle instead of pets. Meaning if any one server were to suddenly die, its a statistic rather then a sadness. So most of our servers dont require backups. Things that deal with persistence (Databases) replicate their data to multiple other servers, and then one of them writes that data to...well...its black magic to me, but theres a team that manages where that goes and what happens to it after.
  5. Riot tries to get every engineer to be a T, a deep tech passion, with a lot of broad knowledge. Each t...

What can I do to reduce jitter/ms fluctuations for league? My isp isn’t the greatest, but it’s like 45 to 65 mbps. I frequently get lag spikes.

Depends a lot on whats causing the fluctuations, if you are using wifi...get wired. If its a shared network more bandwidth or maybe even Qos if your router supports it. If the problem is outside your house, theres not a lot you can do other than complain to your ISP or change ISPs. Take all this with the grain of salt that I dont know much about your situation.

Do you guys have dedicated network security guys (rioters)?
Also, what are some security challenges that running data systems on the scale of riots's present that aren't present in smaller data systems?
Random, why don't you port over to aws to save yourself some headache?

  1. Yes, we have several teams dedicated to various types of security, including network and app
  2. For each publicly available service, you increase your attack surface. Riot has so many in fact that its no longer possible for an individual to even comprehend an entire ruleset, let alone how many rulesets interact with all the others. On a small network I would expect any network engineer to be able to answer "Is port X open to the public any where" but on large networks we have to rely on our tools and automation to tell us that. Not sure if that makes us better or worse.
  3. Cloud Providers offer a lot of things, but there is a break point where the cost of a bare metal server is cheaper. The best thing is a judicious balance of many cloud providers and bare metal, trading back and forth for cost/speed as each use case needs. I would say there is never THE right answer when it comes to infrastructure, neither cloud nor bare metal will solve every problem.

I play from the Philippines and constantly have 200+ ping but no lag till it reaches 300. Why is that?

Its really hard to tell with just that bit of knowledge. If ping suddenly changes, it could mean that the path you take to the game server has changed, or it could mean that something in between is overloaded. If you are using wifi, it could also mean that you are having interference. Theres probably two dozen other reasons, but thats where I would start.
