IT governance frameworks: A literature review of Brazilian publications

IT (Information Technology) governance has been a widely studied subject. This has generated different definitions and conceptual models to explain it. We conduct a concept-centric literature review based on a literature reference model. We used three literature frameworks to identify key-variables to evaluate and classify Brazilian IT governance publications. These variables were used to classify 90 Brazilian publications from 2004 to 2012. The authors chose Brazil due to its economic growth and companies’ internationalization on the last years. The organizations are fonder to regulatory and compliance marks due to market visibility, driving them towards IT governance practices due to growing dependence on IT. The frameworks used in the country are usually developed abroad - then verification on how they fit with Brazilian organizations is relevant to business management. The study shows that; the most used methodology is the case study; 90% of the papers were written in Portuguese; the IT alignment is cited, but not evaluated; few cases are related to small and medium business; and decision structures are not discussed. The authors conclude presenting a conceptual model summarizing all the models and Brazilian companies’ particularities

Automated Refinement of Sustainability-Oriented Policies for a Sustainable Network Management

Abstract-Sustainable networks management represents a significant opportunity for reducing energy consumption among Information and Communication Technologies. Policy Based Network Management (PBNM) is one of the key approaches to bring sustainability to networks. However, despite its potential, PBNM is not yet widely commercially used. The widespread use depends on an automated policies refinement process in order to translate high-level policies into machine-readable policies able to put the business strategies into practice. This work aims at proposing an automated sustainability-oriented policies refinement method, as well as an architecture and a prototype to a sustainable network management

Sustainability information model for energy efficiency policies

The need to manage the energy consumption of network infrastructure has been addressed by a significant body of work in recent years. In general, energy management capabilities were developed independently and optimized for particular network layers and node features. The interaction between multiple such green capabilities when deployed simultaneously, as well as potential interactions with other existing functionality such as quality of service functions, need to be managed transparently by the operators. We developed SLIM, the SustainabiLity Information Model for Energy Efficiency Policies, as an addon to the IETF Policy Core Information Model Extension to allow unifying the management of green capabilities throughout the network. We illustrate the flexibility of our approach by presenting a use case and describing an energy management system where SLIM was used
