33. SCALINGG!
    IaaS Caveat - It’s not automatic unless you build it to be automatic!

34. (Flat out stolen from 12factor.net)
    •Divide apps into types of
    work
    •Separate quick/slow
    processes
    •Rely on the OS or
    Platform to manage
    process lifecycle

36. If you’re using IaaS
    Use clever stuff like chef to treat your Infrastructure as code - it’s
    the easiest way to avoid being locked into one provider
    Most IaaS outfits provide ‘Availability zones’ - use them (or at
    least understand how they work)

    Backups, backups, backups

37. Are there any problems with thinking cloudy?
    Sunday, 9 September 12

38. Absolutely.
    Cloud Computing isn’t a silver bullet - so far from it I can't eeeeeven
    tell you
    Migrating is way harder than building from scratch
    When built wrong, it can go REALLY wrong
    Cloud Computing is still a maturing concept
    Experience and expertise is comparitively thin on the ground
