For those unaware of the effort, I thought I'd point out the existence of an interesting research facility called PlanetLab. In a sense it's the next generation of clustering or grid technology -- the ability to harness overlays of computing power to create virtual distributed computing resources. Somewhat confusingly the name PlanetLabis used to refer to all three of the following:
There's a stupid network spin to this. Instead of the stupid network connecting smart devices, it ends up connecting smart virtual devices. What that means is that the next wave of decentralisation is being hatched.
The Internet grew from the ARPANET et al. Planetlab is to Internet Mk2 as ARPANET was to Internet Mk1. It's an embryonic version of a future phenomenon. Let's say PlanetLab is commercialised, and also grows like the Mk1 Internet. Taken to an the same extreme, you can imagine there wouldn't be data centres filled with expensive fire supression systems and redundant power supplies. You just smear your data and processing across the virtual computing environment and let the natural redundancy of the Internet deal with the consequences of danger and disaster.
So if you're looking for futures giants of data storage or application serving, it'll probably come out of an initiative very much like this. Instead of hording data processing or computing power behind the corporate moat, the next iteration will turn that world inside out -- the power will truly be at the edges. Some of the winners of the first waves of client decentralisation (Sun, Oracle, BEA, etc.) are likely to be hurt by this wave of server decentralisation. Probably too early to rejig your portfolio (and too late if you hold Sun stock). But one to watch.
Imagine if every corporation you dealt with had to store your data in a virtual data store under your own control? I look forward to the day!
UPDATE: Take a look at this excellent summary of the state of play in distributed content distribution. We really are in the midst of a huge technical and social change. Three massive shifts, one after another -- many-to-ones (the Web), one-to-one (VoIP) and one-to-many (P2P). Each displacing whole industries in the process, and creating new ones previously unimagined. All enabled by Stupid networking. What a time to be alive!
