Mega blog entry....The Secret Source of Google's Power

Topix.net Weblog: The Secret Source of Google's Power:

Much is being written about Gmail, Google's new free webmail system. There's something deeper to learn about Google from this product than the initial reaction to the product features, however. Ignore for a moment the observations about Google leapfrogging their competitors with more user value and a new feature or two. Or Google diversifying away from search into other applications; they've been doing that for a while. Or the privacy red herring.

No, the story is about seemingly incremental features that are actually massively expensive for others to match, and the platform that Google is building which makes it cheaper and easier for them to develop and run web-scale applications than anyone else.

I've written before about Google's snippet service, which required that they store the entire web in RAM. All so they could generate a slightly better page excerpt than other search engines.

Google has taken the last 10 years of systems software research out of university labs, and built their own proprietary, production quality system. What is this platform that Google is building? It's a distributed computing platform that can manage web-scale datasets on 100,000 node server clusters. It includes a petabyte, distributed, fault tolerant filesystem, distributed RPC code, probably network shared memory and process migration. And a datacenter management system which lets a handful of ops engineers effectively run 100,000 servers. Any of these projects could be the sole focus of a startup.

What are all those OS Researchers doing at Google? Rob Pike has gone to Google. Yes, that Rob Pike -- the OS researcher, the member of the original Unix team from Bell Labs. This guy isn't just some labs hood ornament; he writes code, lots of it. Big chunks of whole new operating systems like Plan 9.

Look at the depth of the research background of the Google employees in OS, networking, and distributed systems. Compiler Optimization. Thread migration. Distributed shared memory.

I'm a sucker for cool OS research. Browsing papers from Google employees about distributed systems, thread migration, network shared memory, GFS, makes me feel like a kid in Tomorrowland wondering when we're going to Mars. Wouldn't it be great, as an engineer, to have production versions of all this great research.
Google engineers do!

"Google's control over information is going further and further. We use his services every day. He knows us, our questions, our desires, our needs, how we live. Everything is stored into its database. Information is power, commercial power, political power. Who's controlling Google ? http://www.google-watch.org/"
