Architecture

• To set up a distributed web architecture, allowing to have a very high level of robustness and availability.
• By using end users technologies
  • ADSL links
  • Open Source tools
  • Low cost servers

• A distributed architecture
• A robust architecture
• low raliability of the components (failure is not an exeption, it's the rule)
• autonomy of the components
• weak and asynchronous couplings
