    Thanks! Like the human body the more you study the Internet the more amazing it is not that it sometimes breaks, but that it works at all. Especially for video/phone/etc. Glad the …

    As the others say in the comments, understand completely re: servers. And network. And some management overhead. I will write a blog post laying out our COGS at Kentik including al…

    We're (Kentik) a SaaS company and one key to having a great public margin is buying and hosting servers. In our case, we use Equinix in the US and EU to host, with Juniper gear for…

    Unless that's capex for building, or includes server capex that they depreciate, that seems way high given Uber's scale. A pretty dense cabinet should only cost ~$1400/mo at wholes…

    Absolutely a believer in the power of single machine analytics on GB or TB vs PB datasets. But I've found that whether it's a new data system or just showing csv/tsv tool magic, if…

    Many of the alternates (including linux cli stuff) that are much faster require a re-thinking of attitude, don't work where there are tens to hundreds of people submitting queries,…

    We do network analytics delivered as SaaS, selling to enterprise and service providers, but I'm happy to talk (for free, of course) about VCs and the funded life. I have felt like …

    Have you checked whether any of your customers are connected to VCs? Enough of ours are that in our seed, A, and B diligence they found folks to talk about us that I didn't point t…

    At the late stage, investors usually want to see 3-10x vs 10-100x as a realistic range vs earlier stage (A round) investors. Usually they also look to there being a MUCH lower chan…

    If it's just the 2 of you, it might be easier for the company to buy back his shares at the issue price. Need to check with your lawyer, of course, re: valuation issues, but if it'…

    I used to be a Comcast wireless customer, but it cost much more than $45/mo, and was called Comcast Metrophone :)

    I read "typical worst-case pause time" in go and don't know whether to laugh or cry. We are seeing massively longer pauses in production and the suggestion is to go to 1.8, which i…

    Agree that bare metal is effective and doable at your scale, and can if done right give better SLA and much much much better control - especially of Internet-facing network perform…

    Agreed - LeaseWeb, OVH, Hetzner, and even SoftLayer if you call and negotiate can all be great options and have been very stable for many folks for dedicated servers. Generally I r…

    I think they can be pretty efficient and if a handle is kept on what's deployed on top, can be not that much overhead over the cost of the infra (whether it's owned or cloud). But …

    Absolutely agree that collateral damage vs many small-mid-sized hosting providers is 0 in Amazon, though you do still have to deal with the normal 'noisy neighbor' problem by re-cr…

    As to the specific advice, sorry you didn't think it was valuable. But re: it being a PR fluff piece - Nope... Not in this case, and I would bet against that being the case with Fi…

    Sorry to keep being pedantic, but I think it's important to thinking about approaches to scalable and performant TSDBs, and I still disagree :) Your example re: Cassandra is a prob…
