  1. Rant: What Scale is Not

  2. Why am I angry? Scale is used as an excuse.

    “Maybe you’ve never worked on a large system before.” -- Y! Manager 2007

  3. Scale - What is it? “Scalability is the capability of

    a system, network, or process to handle a growing amount of work, or its potential to be enlarged in order to accommodate that growth” --wikipedia

  4. Scale is: Things are working and they aren’t likely to

    break this week. Or next.

  5. Scale is not: • Efficient • Correct • Maintainable •

    Operatable • Documented

  6. Why this matters? Large systems have some inherent qualities, but

    your design decisions are by far the largest contributors to the systems characteristics.
