and in 2010 a still new paradigm the cloud
And in 2010, a (still) new paradigm: the Cloud
  • “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet”
  • Amazon, Google, Microsoft… even L’Oréal !
  • Everything as a service
    • Infrastructure as a service
    • Platform as a service
    • Software as a service
  • Behind the scene: a grid
  • Do not worry, be happy: the cloud takes care of your all your digital activities
  • Issue: digital activity, digital life, life ?
  • For the first time in the history of mankind, some[body, thing] can know everything about your life: your professional data, your friends, the movies/the leisure you like, your friends, your political opinions, your mood…

vision calm technology
« Vision »: « Calm Technology »
  • « The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it »
  • [The objective of pervasive computing is to ] “ … make a computer so imbedded, so fitting, so natural, that we use it without even thinking about it.”
  • “Ubiquitous (pervasive) computing is roughly the opposite of virtual reality. Where virtual reality puts people inside a computer-generated world, ubiquitous computing forces the computer to live out here in the world with people.”
  • « A new way of thinking about computers in the world, one that takes into account the natural human environment and allows the computers themselves to vanish in the background »

Mark Weiser, Xerox PARC, 1991-

PhD course - Milan, March 2010 - 07/09/2014

vision cont d
Vision (Cont’d)
  • [M. Satyanarayanan, 2001]
    • Pervasive computing environment = « one saturated with computing and communication capability, yet so gracefully integrated with users that it becomes ‘a technology that disappears’ »
    • So:
      • “Smart” spaces
      • “Invisibility” and transparency
      • Scalability

PhD course - Milan, March 2010 - 07/09/2014

visions cont d
Visions (Cont’d))
  • « I just want to use these f… so-called smart objects/appliances/… »
  • « I want to get rid of the software/hardware/network organization/structure: I just want to access my personal data and the data I need what ever the place /when ever the time
  • « Put down the barriers »: no network interconnection pb, no computer administration frontiers
  • What about security/privacy ???

PhD course - Milan, March 2010 - 07/09/2014

visions summary
Visions (Summary)
  • The « object-subject » is actor (a first-class citizen) of the system
    • smart objects / smart everything
    • active objects
  • « Intelligence » is, at first, the « network » i.e., the ability to exchange information
  • « Intelligence », is also the ability to self-adapt to the user profile and the context (« context awareness »), to weave into the environment
  • « Ego » is part of the context
  • « Intelligence », finally, is the ability to organize:
    • autonomously (autonomic computing, self healing…)
    • spontaneously

applications of ubi perv comp for today
Applications of Ubi./ Perv. Comp. (for today)
  • Sensor networks (smart dust)
  • Home networks
  • Patient monitoring (personal area networks)
  • Emergency management / battlefield / borders monitoring

Applications of Ubi./ Perv. Comp. for tomorrow… maybe
  • Society and RFID
  • Personal data spaces
  • Web of things
  • Machine To Machine (M2M) / Object To Object (O2O)
    • The never lasting intelligent fridge ?

    • Geopositioned Services: App Store
  • Spimes (Bruce Sterling) ?
  • « Hypermatter » (Bernard Stiegler) ?
  • Do-IOT-Yourself: Arduino / Fab Lab ?

PhD course - Milan, March 2010 - 07/09/2014

back to the vision the cloud
Back to the « vision »: the Cloud
  • An old dream: Computing as a utility (John Mac Carthy: “Computation may someday be organized as a public utility” (1961))
  • A supposed to be user centered vision
    • managing a computer is exhausting
    • the user does not care about the system components: the user just want his problem to be solved
    • eliminate the burden of the software/hardware management
    • allow the user benefit from economies of scale
  • A business vision
    • a small set of computing power providers
    • a global market
    • an integrated « hyper-market »: computing, entertainment, learning ?
    • for the best of the big companies
