Google’s App Engine
Some unstructured thoughts on Google exposing some big web-app hosting infrastructure:
- Obviously using this probably makes you acquisition-friendly and/or more hire-able to Google?
- But does the appearance of a service like this make it more attractive to leave Google? When do those FYIFV T-Shirts come out anyway?
- And if you used to work at Google, and you left, would this style of development be something you'd miss? Would you use a former employer's service as a leg-up in your new gig?
- Have enough people left Google trained in this style of web development to constitute a market segment in their own right?
- Is this a case of programmers commoditising their complements?
- It's probably a good thing that Techcrunch currently has the number 1 match for "google app engine" on Google, right?
What’s Your Online Carbon Footprint?
I just came across a blog post from last May by Rolf Kersten about your CO2 footprint when using the internet. I was particularly intrigued by his estimate of the amount of carbon produced by Google at 6.8 grams per search.
A while ago the 'news' went around that Google could supposedly cut the energy consumption of millions of monitors by changing their website background to black. It turned out only to be true for old CRT monitors, and a bit silly all in all. But I sometimes do a couple of hundred Google searches a day, nevermind the other web-based services I use that are off consuming power on my behalf, and Rolf's post reminded me about an idea I had that I think could really work.
What if Google replaced the "I'm Feeling Lucky" button with one that said "I'm Feeling Patient" instead, and then waited for a convenient moment to perform my search instead of performing it instantly? Would they (could they) reduce the number of servers needed for search if they did that? And will there ever be a point where increased efficiency doesn't get used up by doing more instead of being used as an opportunity to cut back?
I know Gavin Bell has been thinking about these ideas too, wondering how to measure the energy consumption of web services in general, including the effects of mod_gzip on the power consumption of nosy routers that inspect packets at every hop. I wonder about the environmental cost of indexing all those mailing lists I leave archived and unread in my GMail.
Clearly some of these things pale into insignificance when compared with the environmental impact of air travel, long commutes, badly insulated homes, old power grids, etc. but I wonder if they start to be worth thinking about at a company operating on Google's scale.
Carbon-adjusted Computation
Jon Udell at InfoWorld is thinking about the carbon-adjusted supply-chain, using a hypothetical dual-pricing scenario for Amazon. At Euro Foo I attended a session hosted by Claus Dahl on prototyping using Second Life, and we discussed the possibility of a heads-up display to show the computational cost of various processes in the world, perhaps in kWh or even tonnes of carbon.
Right now we're in an "out of sight, out of mind" phase of thinking about the cost of our computing, but the amount of computer power being put to work behind the scenes is staggering. In July of this year, the New York Times reported that Google was likely to be the fourth largest server manufacturer in the world. Can Yahoo or Microsoft be far behind?
I currently subscribe to a large amount of mailing lists with my GMail account, mainly for the convenience of searching them later. But what if Google told me that indexing all that email I don't read was adding up to significant environmental cost? What if Linden Labs told you the energy consumption of all your Second Life possessions? Tom Coates recently looked at the possibility of monitoring home energy usage, but I think we need to approach this from all angles. Never mind unplugging my appliances when I don't need them, I wonder how many servers in data centres across the world are carrying out needless processing on my behalf - what's the carbon footprint of my web-enabled world?
