  • 16. Dedicated Hosting Costs
    Co-Located Servers
    $16,000 (including local disk + B/W)
    But:
    Long lead times for additional servers
    1 year leases
    No durable storage

  • 17. What would I do Today
    Same architecture
    Use a POSIX distributed file system on nodes
    Start will less redundancy
    Work will more smaller instances
    Look at Google App Engine for Web Pages/API
    Use MySQL rather than Postgres
    Worry less about scaling

  • 18. What you should learn
    The mantra
    Compute
    Storage
    Bandwidth
    Transactions
    Know your costs, check your bills
    Code errors will now cost real money
