a selflet system
A SelfLetsystem
  • Composed of many interconnected nodes (SelfLets)
  • Completely decentralized
  • Each SelfLet has a goal and is able to offer services to others with different execution semantics
    • Do
    • Teach
    • Know who can do
  • It is equipped with an autonomic part that continuously monitors the internal and external known environment and changes the SelfLet normal behavior as needed (according to self-* properties)
  • Could represent (part of) an enterprise and cooperate with the others
self properties
Self-* properties
  • Self-configuration
    • System configure itself to reach a defined goal
  • Self-optimization

  • Self-healing
    • Corrective actions have to be performed if the system realizes that has reached a state preventing the reaching of its goal
  • Self-protection
    • System should detect security attacks or anomalies
