Lyft is horribly inefficient in terms of using their AWS resources. I know this first hand. They don't have to build their own DS. They just need to build a better system. Possibly take advantage of Lambdas because a lot of compute heavy operations like geo en/decoding are done in services that run at like 25% CPU in production.
- ghaff 8y agoNot to pick on you specifically as others are saying more or less the same thing... But if you're such a genius that you know how to slash Lyft's AWS spend without knowing basically a thing about their infrastructure, you should be knocking loudly on their door because I'm sure they have an extremely well-paid job waiting for you. Otherwise, maybe consider voicing opinions like these about things you actually know something about. ADDED: Meant to respond to a different comment that didn't suggest any inside knowledge. (Though I'd still point out that even insiders often can't understand how their own company has so many employees in X department, is so inefficient, etc. And this is more or less the case everywhere.
- ceejayoz 8y ago"I know this first hand" implies they do know something about their infrastructure. Given that they work for "one of few >10b unicorns" per their comment history, I have a suspicion you may be telling a Lyft employee they don't know anything about Lyft.

- ghaff 8y agoI actually meant to respond to a different comment which merely said this was a few hours of an AWS instance.
- ceejayoz 8y agoWell, that's factual - you can get a couple hours time on an entire AWS instance for $0.14. That certainly seems to point to an cost-inefficient infrastructure.
- ghaff 8y agoI don't really have an opinion on how efficient or inefficient their infrastructure is. AWS has lots of services and I'm sure Lyft is using a heck of a lot more of them than just a bunch of EC2 instances.
- msoad 8y agoI know exactly how they _can_ improve things but the engineering organization is not well run to do big infra-only projects like that.
