“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

  • 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…

  • All digital, any where, any time Era



  • « 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-



[M. Satyanarayanan, 2001]

  • [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


« I just want to use these f… so-called smart objects/appliances/… »

  • « 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 ???



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
  • Ecosystem

An old dream: Computing as a utility (John Mac Carthy: “Computation may someday be organized as a public utility” (1961))

  • 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
