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 LOréal !
• 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,
  somebody, 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

What has happened to IT ?
12
Technological Evolutions

•  Universal  identification
• RFID - Electronic Product Code (EPC)
  EPCGlobalNetwork Object Naming Service (ONS)
• IETF Host Identity Protocol (HIP)
• Large bandwidth communications
• Optical fiber
• 3G, 3G, 4G, WiMax
• WiFi Direct
• Geopositioning
• GPS/Galileo
• GSM

13
Technological Evolutions (Contd)

• Super computing
• Parallel super-computers (1- Jaguar (224162
  cores, 2,3(1,7) Pflops))
• Super-clusters (Google 1,8 millions of servers ?
  Soon 10 millions ?)
• Super storage
• Key GB
• Disk TB
• Data Center PB
• Micro-Nano technologies
• Sensors Sensor networks
• Convergence digital camera telephone laptop ?
  smartphone

14
Software Evolutions

• Cloud computing
• Social networks
• Services - SOA
• E-Services
• Mobility (M-services)
• Object ? Service / Service ? Object
• All digital, any where, any time Era

15
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-

16
Vision (Contd)

• 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

17
Visions (Contd))

• I just want to use these f so-called smart
  objects/appliances/
• I want to get rid of the software/hardware/netwo
  rk 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 ???

18
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
• Ecosystem

19
Applications of Ubi./ Perv. Comp. (for today)

• Sensor networks (smart dust)
• Home networks
• Patient monitoring (personal area networks)
• Emergency management / battlefield / borders
  monitoring
• Museums and pervasive buildings
• Vehicular Ad hoc NETworks (VANET) / MANET
• Alert management (parking, kids, etc.)
• Supply chain

20
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 ?
• Maintenance Supply chain
• Intelligent sensors networks

21
Applications of Ubi./ Perv. Comp. for tomorrow
maybe(Contd)

• U-Society
• People to People (P2P) Facebook on your
  telefonino
• People to Object (P2O) Pachube
• Geopositioned Services App Store
• Spimes (Bruce Sterling) ?
•  Hypermatter  (Bernard Stiegler) ?
• Do-IOT-Yourself Arduino / Fab Lab ?

22
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

What IT world do you want to build ?
