“…Therefore, a sophisticated coordination mechanism is needed to ensure that the adaptation of the target system occurs in a coherent and consistent way. We argue further in [14] that process workflow technology is a promising approach to addressing that complexity both at the specification and the execution level.…”

“…KX fulfills the controller role by employing our workflow technology called Workflakes [14,18]. Workflakes is a decentralized process enactment engine, specialized towards automated coordination of software entities as previously suggested in [38], as opposed to the more conventional use of workflow to organize human activities (e.g., see [39]).…”

“…The automated adaptation framework, which we have previously presented in [14], supplements the monitoring framework with decision, coordination and actuation capabilities. Based on the coalesced and interpreted sensor data relayed by gauges and on modeled information about the target system, a controller makes decisions on what adaptations (if any) need to be done.…”

“…We describe three such scenarios in this section, dealing with service failures, load balancing, and quality of service across two different legacy systems (additional applications are discussed in [14] and [41]). Because the authors were not involved in the prior development, deployment and systems management of these real-world systems, it is not possible to offer full "before" and "after" comparisons with detailed quantitative data.…”

Retrofitting Autonomic Capabilities onto Legacy Systems

Autonomic computing-self-configuring, self-healing, self-managing applications, systems and networks-is a promising solution to ever-increasing system complexity and the spiraling costs of human management as systems scale to global proportions. Most results to date, however, suggest ways to architect new software designed from the ground up as autonomic systems, whereas in the real world organizations continue to use stovepipe legacy systems and/or build "systems of systems" that draw from a gamut of disparate technologies from numerous vendors. Our goal is to retrofit autonomic computing onto such systems, externally, without any need to understand, modify or even recompile the target system's code. We present an autonomic infrastructure that operates similarly to active middleware, to explicitly add autonomic services to pre-existing systems via continual monitoring and a feedback loop that performs reconfiguration and/or repair as needed. Our lightweight design and separation of concerns enables easy adoption of individual components for use with a variety of target systems, independent of the rest of the full infrastructure. This work has been validated by several case studies spanning multiple real-world application domains.

Abstract. SCM products are large and monolithic, difficult to adapt and evolve, with high entry cost. This paper describes a new approach to SCM in which the system is built from, potentially heterogeneous, existing pieces, with assembly mechanisms that enforce high-level properties. The approach does not provide a simple SCM tool, but a family of tools that is easily customized, fits both lowend users (only the required functionalities are present at a very low cost), as well as high-end users (for which very advanced features and/or specific features can be easily added). The paper describes the concepts and mechanisms of federations, and shows how our federation technology was used to develop a family of SCM systems.
