Slide 1 :



Autonomic Computing

Slide 2 :


==> “Autonomic Computing” is a new vision of computing initiated by IBM.

==> This new paradigm shifts the fundamental definition of the technology age from one of computing, to one defined by data.

==> Access to data from multiple, distributed sources, in addition to traditional centralized storage devices will allow users to transparently access information when and where they need it.

==> At the same time, this new view of computing will necessitate changing the industry's focus on processing speed and storage.

Slide 3 :

Control loops

==> A control loop can be provided by a resource provider, which embeds a loop in the runtime environment for a particular resource.

==> In this case, the control loop is configured through the manageability interface provided for that resource

==> In some cases, the control loop may be hard-wired or hard coded so it is not visible through the manageability interface

==> They regulate themselves and, sometimes, each other.

==> They can proactively manage the system, while hiding the inherent complexity of these activities from end users and IT professionals

Slide 5 :

Autonomic Manager

==> The monitor part provides the mechanisms that collect, aggregate, filter, manage and report details collected from an element.

==> The analyze part provides the mechanisms to correlate and model complex. These mechanisms allow the autonomic manager to learn about the IT environment and help predict future situations.

==> The plan part provides the mechanisms to structure the action needed to achieve goals and objectives. The planning mechanism uses policy information to guide its work.

==> The execute part provides the mechanisms that control the execution of a plan with considerations for on-the-fly updates

Slide 7 :

A Grand Challenge

==> The computing paradigm will change from one based on computational power to one driven by data.

==> The way we measure computing performance will change from processor speed to the immediacy of the response.

==> Individual computers will become less important than more granular and dispersed computing attributes.

==> The economics of computing will evolve to better reflect actual usage - what IBM calls e-sourcing

Slide 8 :

Monitoring Engine

==> Monitoring Engine, now available in IBM Tivoli Monitoring, enables root-cause analysis for IT failures, server-level correlation of multiple IT systems, and automated corrective measures

==> With the complimentary IBM Tivoli Monitoring Resource Model Builder, it has become easier to createAutomated Best Practices for monitoring and delivering autonomic self healing capabilities for IT systems

==> Working with the IBM Tivoli Monitoring family of products, the IBM Tivoli Resource Model Builder allows quickly deliver greater value to to customers with better managed IT systems

Slide 9 :

Business Workload Manager

==> Business Workload Management for Heterogeneous Environments, which will be soon out in IBM Tivoli Monitoring for Transaction Performance Version 5.2 , uses the ARM standard to determine why bottlenecks happen, using response time measurement, transaction processing segment reporting, and learning of transaction workflow through servers and middleware.

==> The software then adjusts resources to avoid bottlenecks

==> Planned functions include the ability of BWLM to detect changes in its environment and decide which resources to adjust in order to enable a network of systems to meet end-to-end performance goals

Slide 10 :


==> We must look to scientists studying nonlinear dynamics and complexity for new theories of emergent phenomena and robustness.

==> We must look to psychologists and human factors researchers for new goal-definition and visualization paradigms and for ways to help humans build trust in autonomic systems.

==> We must look to the legal profession, since many of the same issues that arise in the context of e-commerce will be important in autonomic systems that span organizational or national boundaries

==> It’s going to have to be an open source system because there are so m any parts. These parts will provide plenty of opportunity for competition.
