A quote from an Ex-Googler

I really like this paragraph, because almost everyone wants to imitate google. Why? well, the answer to that questions seems to be what everyone is missing!

Google’s solutions were built for scale that basically doesn’t exist outside of a maybe a handful of companies with a trillion dollar valuation. It’s foolish to assume that their solutions are better. They’re just more scalable. But they are actually very feature-poor. There’s a tradeoff there. We should not be imitating what Google did without thinking about why they did it. Sometimes the “whys” will apply to us, sometimes they won’t

The quote comes from Cloud Field Day 4, from Ben Sigelman of LightStep.

Thanks to Tom over at for the entire post!


Complicated Vs. Complexity

I am currently reading Team of Teams, an excellent book!

In it, it highlights an interesting fact that I think is very relevant for the networking world and that is the difference between something that is complicated versus something that is complex.

There is a distinct difference in that something complicated can be broken down into its building blocks and analysed with a high degree of certainty. Think of a car engine for example. It is a very complicated piece of machinery for sure, but it is not complex, since you can divide its functionality down into components. On the other hand think of something like a virus and how it evolves. This is a complex organism that you you can’t be certain that will evolve in a predetermined fashion.

So im thinking, the way we build networks today, are we building them to be “just” complicated or are they really complex in nature instead? – The answer to this question determines how we need to manage our infrastructure!

Just some food for thought!


Upcoming webinar with Daniel Dib

Just wanted to let you know that Daniel from is doing a webinar on network design. I will be attending and helping out any way i can.

Go here to learn more:

CRS/ASR Switching fabrics

At the moment I’m going through whitepapers, Cisco Live 365 presentations and IOS XR fundamentals learning about switching fabrics.

Its a steep learning curve, but in its own way its quite fascinating.

There are a lot of acronyms to be mastered, so later on i will post a list that might serve myself and others when looking at these sort of architectures.
