Cloud Computing emerges as a paradigm of computing resources utilization where hardware infrastructure, software and development platforms for new applications are provided as services available worldwide. Such services are o ered using large scale datacenters where virtualization technologies are frequently used so that a multitenancy-enabled architecture can b e deployed. In this context, the e cient management of the datacenter infrastructure can lead to signi cant reduction of its op erational costs. This work presents a management strategy for virtualized datacenters infrastructures that applies b oth distributed monitoring techniques and centralized control actions. Such strategy aims to attenuate overloading problems observed in traditional management mo dels based on a controller that is responsible for monitoring and controlling the infrastructure. Thus, it intends to increase the datacenter's scalability and improve its p owere ciency without compromising the Quality of Service o ered to the end user. The strategy's p erformance evaluation is made through multiple simulation experiments which use tools aimed speci cally at mo deling cloud infrastructures with support to power consumption representation
