Why Autonomic Systems ?

System and Application

Complexity Growth

Brittle, Unmanageable, Insecure

Technological advances

High Growth

More Complex Systems

Concept Derived from Biology

v Strategies based on biological systemsv Inspired by Autonomic Nervous System in the human body.

Defined as : - A self managing autonomous and ubiquitous computing

environment that completely hides its complexity, thus providing the user

with an interface that exactly meets his/her needs.

Four aspects of self-management often cited by IBM

Self Healing

Self Configuring

Current ComputingCorporate Data centers have multiple vendors and platforms. Installing, configuring and integrating systems is time consuming and error prone.

Autonomic ComputingAutomated confihuration of components and systems follows high level policies. Rest of system adjusts automatically and seamlessly.

Self Protecting

Anticipate, detect, identify and protect against attacks from anywhere.

- Defining and managing user access to all computing rsources.- Protecting against unauthorized resource access, e.g. SSL- Detecting intrusions and repoting as they occur.

Self Optimizing

Monitor and tune resources automatically

- support operating in unpredictable environment.- Efficient maximization of

resource utilization without human interference.

Dynamic resource allocation and management.

- Resource: Storage, databases, networks.

Autonomic Systems: Composition of Autonomic Elements

• Solution of today’s increasing complexity in computing

science

Self-Management and dynamic adaptive behaviors

• Still challenges in diverse fields of science and

technology

– Autonomic behavior in one field of science

System managements, software engineering, etc.

– Needs for a abstraction and co-operation in relevant fields.

Autonomic computing is Solution of today’s increasing

complexity in computing science
