"Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google’s Datacenter Network"
"Google’s data centers power the most demanding interactive, storage, and cloud services in the Internet, all requiring the highest levels of availability. Bandwidth and scale demands are growing exponentially, doubling approximately every year. Thus, Google’s data center network architecture must deliver cost-effective networking operating at the granularity of tens of thousands of servers, all while maintaining operational simplicity. We present a first look into Google’s data center network design and implementation, focusing on the data, control, and management plane principles underpinning five generations of our network architecture."
Inside Google, their technology is awesome but I think they need to get very solid in customer support to compete. You can quickly get tech help on the phone from Microsoft and Amazon, and Google needs to match that. That said, I have never signed up for their premium support so I might not be totally fair in this criticism.
- Things like BigQuery require less support in general (managed aspect of it = economies of scale of support. Think gmail support req's versus exchange)
- Higher levels of support come with dedicated Google engineers, and they're not bad
EDIT: Maybe a better question is, at what point do you think about eschewing the traditional Cisco/Juniper gear and look towards these techniques?
Answer 1: when it's cheaper.
Answer 2: when traditional gear gets in the way.
My guess is it's mostly 1 and rarely 2 for most organizations. Might be a combination of both.
I'd argue that traditional gear gets in the way a lot more than most people know / would think, but because you can pull any John Q Public off the street to support a Cisco or Juniper environment, "no one was ever fired for buying IBM" applies. Even investments in the common non-core networking gear is usually limited to just a handful of vendors so diversity isn't really a problem in most cases.
It's a blog post announcing they're going to be presenting some new information on their network topologies at a conference this week, so not sure what you'd expected that's getting you so bent out of shape. Moreover it's a post with some impressive-sounding numbers and links to some legitimately interesting (albeit year or more old) publications. Seems like that puts it easily above 1/3 of front page submissions just right there.
