Increasing hardware performance of desktop computers accounts for a low-cost computing potential that is waiting to be efficiently used. However, the complexity of installation and maintenance of a large number of distributed heterogeneous computers is limiting the use of such systems on a large scale. Systems which are autonomic, capable of managing themselves are required. The architecture of...

Autonomic computing, a new deployment technology introduced by IBM a decade ago, to manage the ever increasing complexity of IT systems, has become a part of many large scale deployments today. A lot of inroads have been made by autonomic computing in the areas of networking, data centers, storage, and database management. But few attempts have been exercised in business applications such as ER...

THIS PhD work takes place within a broader context of service-oriented computing. Precisely, it defines an autonomic Enterprise Service Bus (ESB) with self-management ability regarding certain aspects. This ESB, named autonomic Cilia, allows the simplified development of context-aware mediation applications. Autonomic Cilia permits the runtime optimization of resources used by its execution mac...

Autonomic systems offer numerous advantages over non-autonomic systems, and many of these advantages relate to ease of use. The advantages regarding ease of use include reducing the number of low-level system administration tasks, simplifying the system administrator’s interface, handling exceptions which would otherwise have resulted in system alerts, and the learning, by the system, of action...

An autonomic system provides self-adaptive ability that enables system to dynamically adjust its behavior on environmental changes or system failure. Fundamental process of adaptive behavior in an autonomic system is consist of monitoring system or/and environment information, analyzing monitored information, planning adaptation policy and executing selected policy. Evaluating system utility is...

New distributed systems are running onto fluctuating environments (e.g. ambient or grid computing). These fluctuations must be taken into account when deploying these systems. Autonomic computing aims at realizing programs that implement self-adaptation behaviour. Unfortunately in practice, these programs are not often statically validated, and their execution can lead to emergent undesirable b...

No longer is the question whether autonomic computing will gain general acceptance but when. Experts like Alva Couch expect autonomic computing to be widely used within 10 years [1]. When it does become mainstream, how will autonomics change system administration and corporations, and will the change be for better or worse? The answer depends on how well we anticipate the limitations of what au...

Today’s skilled IT professionals bring to bear an enormous amount of knowledge about how systems are configured, how they function on a day-to-day basis, and how to repair them when they break. However, there are not enough skilled IT professionals to meet the ever-growing demand. Autonomic computing offers a way out of this dilemma: offload the responsibility of managing complex systems onto t...

The prolifeation of Internet technologies, services and devices, have made the current networked system designs, and management tools incapable of designing reliable, secure networked systems and services. In fact, we have reached a level of complexity, heterogeneity, and a rapid change rate that our information infiastructure is becoming unmanageable and insecure. This had led researchers to c...
