Evolution for the sustainability of internetware

Abstract

Along with the green attentions and efforts on energy efficiency of computer hardware and embedded systems, software relevant sustainability issues are becoming increasingly focused, as a part of Green Information Technology (GIT). Undoubtedly, software evolution capability is a vital part in achieving such sustainability, as software that is not adaptable will become obsolete sooner or later. Internetware is currently one of the prevailing paradigms of software evolution, known as its autonomous, cooperative, situational, evolvable, emergent and trustworthy. In this paper, we propose an approach of evolution focusing on sustainability for Internetware software entities. Targeting certain software systems which cannot actively control their functions, service components or attached actuators energy-efficiently, the proposed transformation mechanism can intelligently implement power management adaptations using Web Ontology Language (OWL) -based user behavioral profiles and reasoning mechanisms. In the effort of increasing the sustainability, the transformation consequently enables a greener, predicted and rapidly adapted evolution.

Software architecture construction and collaboration based on service dependency

“…In addition, the authors of [4] proposed a mechanism to construct a new execution path by ignoring the problematic service if one of the service nodes fails to perform its task.…”

“…Based on Service-Oriented Architecture (SOA), Software as a Service (SaaS) and Cloud Computing turn non-trivial software and infrastructure capabilities into business services that can be massively subscribed and consumed through the internet [4]. In the SaaS delivery model, software is presented to the end users who rent software by the tenant as services on demand, usually in a browser.…”
