In this context two different models and expert surveys are used in this study to evaluate the readiness level of the city of Medellin to adopt smart grid technologies. The results of this study show that the City has the utilities, the knowledge, the universities and the human resource to become a role model in the region. But an effort to integrate all the actors and impulse a common agenda is required. The utility companies need to lead this development, but regulators, academia and industry must back up this endeavor and enable Medellin to lead the power grid development of the next years in the region.}, language = {en} } @article{PetruchStantchevTamm2011, author = {Petruch, Konstantin and Stantchev, Vladimir and Tamm, Gerrit}, title = {A Survey on IT-Governance Aspects of Cloud Computing}, series = {International Journal of Web and Grid Services}, volume = {7}, journal = {International Journal of Web and Grid Services}, number = {3}, pages = {268 -- 303}, year = {2011}, abstract = {The purpose of this work is to provide a representative survey of current trends in the perception, assessment and adoption of cloud computing within the enterprise. Cloud computing can be regarded as the general principle for using and providing web and grid services. First, we provide a meta-study, where we evaluate existing and published empirical studies. Furthermore, we conduct and evaluate an own empirical study with a representative group of European and International enterprises. Key findings of the work include the significantly higher importance of Business Drivers for the adoption of cloud computing, as compared to Technical Drivers.}, language = {en} } @incollection{StantchevTamm2011, author = {Stantchev, Vladimir and Tamm, Gerrit}, title = {Addressing Non-Functional Properties of Services in IT Service Management}, series = {Non-Functional Properties in Service Oriented Architecture: Requirements, Models and Methods}, booktitle = {Non-Functional Properties in Service Oriented Architecture: Requirements, Models and Methods}, publisher = {IGI Global}, address = {Hershey}, publisher = {SRH Berlin University of Applied Sciences}, pages = {324 -- 334}, year = {2011}, abstract = {A key point that remains to be addressed is the assurance of service levels for end-user applications that rely on these provider models.

The approach is based on reference models such as the IT Infrastructure Library (ITIL) and the SOA life cycle model. It has been applied in several industrial settings in the telecommunications sector.}, language = {en} }
