Maybe it's because I'm also in retail IT and have seen similar models, but I get it. At the risk of oversimplifying, they've got two problems - code written in an office somewhere has to run identically in 2000 geographically separated places, and it needs to do so with some level of protection against failure. All other K8s gloss aside, it's a good way of making sure that there are multiple instances of a Docker container running. Assuming they set the cluster up correctly, they can suffer hardware failure and not downtime, and assuming they're using those little nucs in the photo, they can do so for under $1500. Sure a single server-grade piece of hardware would probably do just fine and have similar protection from failure, but this is essentially that on commodity hardware.
- coffeesn0b 8y agoOur cost is actually something like $900 for the whole cluster :) . Consumer grade clustering FTW!
- eddieroger 8y agoThat's awesome. Nice article, by the way. How much of the restaurant runs on these clusters, if you can share (rough percentages are fine). I doubt there's a whole POS server on there, but maybe?
- coffeesn0b 8y agoWe're still in the process of rolling things out, although I'm not sure I can give a percentage... I think it's safe to say that in the next 6-12 months most (if not all) of them should have an active cluster. And no, there is not a full POS server on them at this time... it will take us a few years to decompose that monolith, but this is a natural place to put it as we do so.
