THE VISION OF
AUTONOMIC COMPUTING
WHAT IS AUTONOMIC COMPUTING ?
“ Autonomic Computing refers to computing
infrastructure that adapts (automatically) to meet the
demands of the applications that are in it “
A classical example for an Autonomic System – the
human body
These are intelligent systems that are able to
operate, manage and improve their own operations with
minimum or with no human intervention.
NEED FOR AUTONOMIC SYSTEMS
Drivers
• increasing technological complexity
• increased size of computing infrastructure
• ballooning maintenance costs of infrastructure
• shortage of skilled labour
BENEFITS OF AUTONOMIC COMPUTING
Self-Management
BENEFITS OF AUTONOMIC COMPUTING
SELF-MANAGEMENT
• Self-healing
detect improper operations and initiate corrective
actions before they occur, without disrupting system
applications or business processes
• Self-configuring
adapt dynamically to changes in
environment with little human intervention
the
IT
BENEFITS OF AUTONOMIC COMPUTING
• Self-protection
detect and identify hostile behaviors and take
autonomous actions to protect itself against intrusive
behaviors
• Self-optimization
efficiently maximize resource allocation and
utilization so as to ensure optimal quality of service
while continuing to meet users’ needs with minimal
human intervention
CHARACTERISTICS OF AUTONOMIC
COMPUTING
• To be Autonomic, a computing system needs to “ know
itself ” – and comprise components that also possess a
system identity.
• An Autonomic Computing System must configure and
reconfigure itself under varying and unpredictable
conditions.
• An Autonomic Computing System never settles for
Status quo – it always looks for ways to optimize it’s
working
CHARACTERISTICS OF AUTONOMIC
COMPUTING
• An Autonomic Computing System must perform
something akin to healing – it must be able to recover
from routine and extraordinary events that might cause
some of it’s parts to malfunction
• A Virtual World is no less than the Physical world, so an
Autonomic Computing system must be an expert in selfprotection
• An Autonomic Computing System knows it’s
environment and the context surrounding it’s activity,
and acting accordingly
CHARACTERISTICS OF AUTONOMIC
COMPUTING
• An Autonomic Computing System cannot exist in a
Hermetic Environment
• An Autonomic Computing System will anticipate the
optimized resources needed while keeping it’s complexity
hidden

Autonomic Element
Autonomic Systems will be interactive collections of
autonomic elements – individual system constituents that
contain resources and deliver services to humans and
other autonomic elements
ENGINEERING CHALLENGES
i. Life cycle of an Autonomic Element
• Design, test and verification
• Installation and configuration
• Monitoring and problem determination
• Upgrading
• Managing the life cycle
ENGINEERING CHALLENGES
ii. Relationships among autonomic elements
• Specification
• Location
• Negotiation
• Provision
• Operation
• Termination
ENGINEERING CHALLENGES
iii. System wide issues
• Security
• Privacy
• Trust etc
iv. Goal specification
SCIENTIFIC CHALLENGES
i. Behavioral abstractions and models
ii. Robustness theory
iii. Learning and optimization theory
iv. Negotiation theory
v. Automated statistical modeling
PATH TO AUTONOMIC COMPUTING
•
Basic Level – IT professionals set up & monitor each infrastructure
element.
•
Managed Level – system management technologies used to collect
information from disparate systems on fewer consoles.
•
Predictive Level – Elements recognize patterns, predict optimal
configuration & provide advice on course of action.
•
Adaptive Level – Systems themselves can take the right actions
based upon the info that is available to them.
•
Autonomic Level – IT infrastructure governed by business policies
& objectives. Users interact with the autonomic technology to
monitor the business processes, alter the objectives, or both.
