Eight Goals for a System
1. System must know itself
2. System must be able to reconfigure itseld within its
operational environment
3. System must pre-emptively optimise itself
4. System must detect and respond to its own faults as
they develop
5. System must detect and respond to intrusions and
6. System must know its context of use
7. System must live in an open world
8. System must actively shrink the gap between
user/business goals and IT solutions

Autonomic Computing
• Basic model: closed
control loops
– Based on Process
Control Theory
• Controller
compares the actual
and expected
behavior and makes
needed adjustments
measurement adjustment
SEE: Any control-theory books

Autonomic Control Loop
Use uncertain reasoning
Policies, rules, …
Collate, combine,
Find trends, correlations
Modify behavior,
Inform users,
From system elements,
Users, environment, agents, …

Fault models
• Each aspects describes a characteristic of
the fault.
– Duration: Is the fault permanent?
– Manifestation: What does the fault do to the
– Source: Where does the fault come from?
– Granularity: Is the fault global or local?
– Occurrence expectation: How often will the
fault occur?

System Response
• Each aspect describes a characteristic of reacting
to faults.
– Detection: How does a system detect faults?
– Degradation: Will the system tolerate running in a
degraded state?
– Response: What does a system do when the fault
– Recovery: Once a fault occurs, can the system return to
a healthy state?
– Time: How much time does the the system have to
respond to a fault?
– Assurance: What assurances does a system have to
maintain while handling a fault?
