A cada dia nós produzimos mais dados que, em muitos casos, são armazenados em meios digitais. A previsão é que o tamanho desse “universo digital” chegue a quase 8 ZettaBytes em 2015. Essa grande quantidade de dados gerados pode ser armazenada em nuvem utilizando o conceito de armazenamento em nuvem, que é um dos serviços que fornecem recursos para...

This course aims to present in a theoretical way, the cloud computing concepts (features, deployment model and services), along the peer-to-peer network related technologies (features, architecture and design), as well its feasibility , applied to the approach known as p2p-storage in the STaS (Storage as a Service) and DaaS (Data as a Service) cont...

Monitoring and evaluating distributed systems at runtime is a difficult effort. Network traffic analysis may be used to analyse distributed systems, but the capacity to analyse large amount of traffic is a challenge. This work proposes the use of MapReduce for deeply inspecting distributed systems network traffic, evaluating the effectiveness and t...

Testing, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the ability to analyze large amo...

With increasing connectivity speed and Web systems evolution, emerges the Internet systems, which are more commonly called cloud computing. It´s designates a support platform that provides: management, on-demand use, fitness requirements, rational use of resources and automation of processes related to creation of infrastructure. On this context em...

The increase of the peer-to-peer networks popularity is related to de-centralized resources sharing, where peers could exchanging messages among theirs. Through the aggregation and replication techniques, this model offer more robustness and performance when compared to client-server model. In this context, where the peer-to-peer paradigm was selec...
