Autonomic Computing

     

The term "autonomic" comes from an analogy to the autonomic central nervous system in the human body, which adjusts to many situations automatically without any external help. With the increasing complexity in dealing with distributed systems, solutions, and shared resources in grid environments, we require a significant amount of autonomic functions to manage the grid.

As detailed in Figure 4.2, basic autonomic computing systems must follow the four basic principles: [1]

  • Self-configuring (able to adapt to the changes in the system)

  • Self-optimizing (able to improve performance)

  • Self-healing (able to recover from mistakes)

  • Self-protecting (able to anticipate and cure intrusions)

Figure 4.2. Autonomic computing vision is robust across several complimentary dimensions.

Orchestrating complex connected problems on heterogeneous distributed systems is a complex job and requires a number of autonomic features for the infrastructure and resource management. Thus, it is important that our systems be as self-healing and self-configuring as possible in order to meet the requirements of resource sharing and to handle failure conditions. These autonomic enhancements to the existing grid framework at the application and middleware framework level provide a scalable and dependable grid infrastructure.

IBM, the pioneer in worldwide autonomic computing initiatives, has already implemented a number of projects around the world in this general concept, while keeping in mind the synergies to create global grid solutions. These global grid solutions are continuously being enhanced to include autonomic computing capabilities. Grid Computing and autonomic computing disciplines will continue to work closely together to develop highly reliable, efficient, self-managing grids. It is these two computing disciplines that alone serve as the basis for the IBM Corporation's global strategies underpinning Business On Demand. [2]
