SLA-Driven Predictive Orchestration for Distributed Cloud-Based Mobile Services
"... Abstract—We describe a system for performing SLA-driven management and orchestration of distributed infrastructures composed of services supporting mobile computing use cases. In particular, we focus on a Follow-Me Cloud scenario in which we consider mobile users accessing cloud-enable services. We ..."

A computação em nuvem tem vindo a ser progressivamente adoptada em diversos cenários, ofer-ecendo acesso a pedido a um ambiente de recursos distribuídos de larga escala, de forma flexível e altamente escalável, orientada ao acordo de nível de serviço. A virtualização é a tecnologia base dos sistemas de computação em nuvem, dotando-os de serviços flexíveis e escaláveis. À medida que estes sistemas distribuídos se tornam mais comuns, as empresas e fornecedores destes sistemas constrõem maiores centros de dados para lidar com a crescente procura por recursos de computação. No entanto, a quantidade de energia elétrica consumida por estes centros de dados aumenta com o poder computacional instalado. Na mesma linha, à medida que os sistemas de computação crescem em tamanho e em complexidade, eventos de falha tornam-se norma em vez de exceção, aumentando ainda mais o desperdício energético e afetando a Qualidade de Serviço do sistema percecionado pelo utilizador final. Além disso, as tecnologias de virtualização atu-ais não fornecem isolamento de desempenho, o que significa que duas aplicações executando em máquinas virtuais independentes e que partilham o mesmo servidor podem interferir na execução uma da outra, e consequentemente violando as restrições de Qualidade de Serviço. Esta tese apresenta dois mecanismos aperfeiçoados com o duplo objetivo de reduzir os custos

The spectre of climate change that is unfolding now is undeniably a cumulative impact of anthropogenic interference in the climate system over the last two centuries. The science is clear and the policy community is being increasingly convinced and galvanised into action to address this emergent challenge in light of the associated economic and human dimensions. The impacts of climate change ranging from sea level rise, melting ice caps and glaciers, severe weather events, drought, flooding, warming, subtle changes in ecosystems – will impinge on every aspect of society and economic life. The costs of inaction will more than outweigh the costs of action. There is only a narrow window of opportunity to redress the situation. The Intergovernmental Panel on Climate Change (IPCC) in its Fourth Assessment Report has

The aim of this work is twofold: to understand the intuitive sense of mechanism that accounts for commonsense predictions, expectations, explanations, and judg-ments of plausibility concerning mechanically causal situations and to understand how those intuitive ideas contribute to and develop into s ..."

The framework is aimed at answering, at a coarse level of detail, a set of questions central to a full theory of knowledge: What are the elements of knowledge
