Data Centers
®Best place to store persistent data
®(device is second best)
®Can justify backup power, networking, physical
security
®Cheapest source of storage/computer per user
®100-1000x less than a personal device (!)
®Factors: shared resources, admin cost, raw costs (power,
disks, CPUs)
®Berkeley will be the data center for our early
work…
®Proxies: shared local computation and caching
®Linux PC or Xscale box
