Map-reduce, Hadoop and Clouds - When and When Not (aBlog)

  • In this article, I want to focus on two specific cool
    technologies that frequently go hand-in-hand: Google's Map-reduce
    (e.g. Hadoop), and Cloud Computing (e.g. EC2). For whatever
    reasons possibly including those I've mentioned above, temptation is high among
    many engineers today to use these sledge hammers to crack nuts.
  • as it turns out,
    our problem is very different in scale from,
    say, computing ranks on every document on the web. In fact, our graph
    is small by comparison, and we can afford to do most of our
    calculations on this graph in memory and in real-time. We
    are often able to get away with efficiently processing, within each of
    many simultaneous threads, the edges of any particular node in
    sequence. To be sure, one can indeed Hadoop this process by clever
    definitions of functions that will do the kind of recursive
    aggregation for the quantities that interest us. But we want to see
    if it is necessary at all, and for the foreseeable future at least.

Creating Strategy in an Unknowable Universe - HBS Working Knowledge

  • This article suggests an evolutionary way to business strategy. Rather than thinking of strategy as a single plan, we can think of it as a population of competing business plans subject to selection. - alexko on 2006-11-18
