- Optimization, high availability and redundancy in information communications and technology using networks and systems virtualization architecturesPublication . Monteiro, Narciso Artur Caldas Sousa; Costa, António Manuel Cardoso da; Brandão, António MorimIn an era marked by the so-called technological revolution, where computing power has become a critical production factor, just like manpower was in the industrial revolution, very quickly this dispersal of computing power for numerous facilities and sites became unsustainable, both economically as well in terms of maintenance and management. This constringency led to the need of adopting new strategies for the provision of information systems equally capable but in a more consolidated way, while also increasing the desired levels of the classic set of information assurances: availability, confidentiality, authenticity and integrity. At this point enters a topic not as new as it may seem, virtualization, which after two decades of oblivion presents itself as the best candidate to solve the problem technology faces today. Throughout this thesis, it will be explained what this technology represents and what approach should be taken in the evolution of a systems architecture classical model into a model based in optimization, high availability, redundancy and consolidation of information communications and technology, using networks and systems virtualization. A number of good management principles to adopt will also be taken into account to ensure quality standards in providing services, culminating in a practical application of this model to the infrastructure of the company Metro do Porto, SA. Briefly, this document can almost be classified as a step by step manual for the understanding and implementation of this model, transversal to any infrastructure without extremely particular needs or constraints which derail conversion.
