The increasing development and utilization of services based on cloud facilitates the development of sectors like entertainment through media streaming. Platforms such as Eucalyptus provide Infrastructure as a Service (IaaS), allowing to create and manage a wide variety of services on cloud. Redundant mechanisms are commonly adopted to achieve improvements of availability, since this issue is critical for providing a cloud service. This paper analyses the impact of adopting a redundant component for a VoD streaming service based on Eucalyptus platform, comparing these results to a non-redundant proposal. The proposed solution revealed an reduction of 51.01% in annual downtime compared to the non-redundant proposal. Sensitivity analysis was used to identify availability bottlenecks to the proposed redundant architecture.
