What is Autonomic Computing?

Autonomic Computing is anapproach, to self-managed

computing systems with aminimum ofhumaninterference.

The term autonomic comes

from the autonomicnervous system.

Why is this a Problem?

Software bugs and

hardware failures

Complexity in runningand managing the ITinfrastructure

Difficulty indeployment ofcomplex systems

Too many users, notenough resources

Too many computational

devices

Human management of

increasingly complexsoftware systems isexpensive, time-consuming, and error-prone

THE SOLUTION

The answer is, to give this large problem to the computer tofix.

Goal is to develop technologies to enable self-managingsoftware systems

Many R&D communities are excited about the idea of self-managing systems: enterprise applications, networking,safety-critical systems,high-performance computing,

And are building newsoftware systems with self-management capabilities

Flexible. The system will be able to sift data via a

platform- and device-agnostic approach. Accessible. The nature of the autonomic system is that it

is always on.

Transparent. The system will perform its tasks and adaptto a user's needs without dragging the user into theintricacies of its workings.

Autonomic Computing

Self-managing systems that

Increase

Responsiveness

Adapt to dynamically

changing environments

Business Resiliency

Discover, diagnose, and

act to prevent

disruptions

Operational Efficiency

Tune resources and

balance workloads tomaximize use of IT

resources

Secure Information

and Resources

Anticipate, detect,identify, and protect

against attacks

...achieving the correct balance between what is managed by a person

versus the system

Core Building Blocks foran

Analyze Plan

Knowledge

Element

Sensors Effectors

An autonomic elementcontains a continuouscontrol loop that monitorsactivities.

For a system component tobe self-managing, it musthave an automated methodto collect the details itneeds from the system; toanalyze those details to

determine if somethingneeds to change; to create

a plan, or sequence ofactions, that specifies thenecessary changes; and to

perform those actions.

But what about Legacy Systems?

A legacy system is anysoftware system that alreadyexists and is in use - such asthe nations critical informationinfrastructure and

defense information systems Replacing all existing systems

withnewautonomic computingsystems would be veryexpensive and take a long time

Any existing system that isntalready a self-managing system

Designers may be long-gone May be too expensive or take

too long to build a new system

nalysis

Detect particularpatterns of eventsfrom individual sensors

and across multiplesensors over periods oftime

Determine whethersomething went wrongor is anomalous(unexpected)

Decide whether andwhen to dosomething and

what to do tomodify the legacysystem

How does autonomic computing

help customers?

Improved resiliencyand quality ofservice

Always there when

youneed it

Safe and secure

Accelerated time tovalue

Optimizes productivityand business value

Faster deployment ofapplications thatexecute businessstrategies

Increased return on IT investment (ROI) Better asset utilization

More productive people

Reinvestment of IT productivity and cost

The journey has started

Products, services available today

Architecture and core technologies emerging

IBM is working with business partners and

standards organizations to develop open standards

for self-managing systems

Broad IT industry participation is needed this is an

industry-wide initiative

Innovation is required!! Aggressive research isessential!!

Freeing people to focus

on their business instead of

their infrastructure
