  • talk
    • official slides http://www.slideshare.net/olg/webworkerscamp-2010
    • step back : what we can play with, what are the constraints, ...
    • think about tuning for the whole architecture
    • key papers
      • GFS
      • Map/Reduce
        • Hadoop, Cassandra, ...
      • REST
    • frameworks and infrastructure started to adopt those principles
    • fantasmatic questions by clients
      • "I want to scale like Google or Amazon"
      • "I need async!"
    • historical implementations
      • Nutch 2003 -> Memcached 2003 -> Rails 2004 -> CouchDB 2005 -> S3 & eC2 2006 -> Node.JS ...
      • longevity?
    • what parameters can we change
      • classics
        • # of backend servers, cache size, fsync/checkpointing, invar?
      • closer to the architecture, the "proper" ones
        • Consistency level, Syn/Async mix, R/W actions balance, model heterogeneity
      • in the end... it's what provides value for our application that count
        • fundamental constraints, ...
    • impact of Google PageRank
      • they take latency into account
      • is it a strategical move to promote their own tools?
    • storage
      • SQL, NoSQL, ... re-ask the questions of how the application must work
        • question the bias the tools you are using and how they impact your work
      • CAP, ACID -> can you change anything beside Consistency?
    • mention of Configuration management software
      • configuration must be managed too
      • avoid ssh, administrative change must be versionned, automatized, ..
      • infrastructure is code
    • the real advantage of the Cloud is to understand what breaks
    • promotion of MyPAAS
      • rather than GAE, Heiroku, (Azure?), ...
    • Q&A
      • then, what decision to take?
        • warning of platform lock-in
          • example of Google
        • where does my application provide value?

      1. virtual machines
      2. tools
      3. Programming#LiveCoding
    4. link analysis
      1. do not exclude google.com overall as code hosting, including V8 is on it
    5. live blogging (Twitter, identi.ca, ...) opened in the side
      1. Firefox bookmarked with the option to open on the sidebar

    6. look for others reviews/notes after the events
      1. twitters, blogs, ...
    7. summarize as a template
      1. cf Template that could here be applied to live streams

      1. locally
        1. remotely
          1. locally as a remote closure
