Nowadays, service providers in the Cloud
offer complex services ready to be used as it was a commodity like water or electricity to their customers. A key technology for this approach is virtualization which facilitates provider's management and
provides on-demand virtual environments, which are isolated and consolidated in order to achieve a better utilization of the provider's resources.
However, dealing with some virtualization capabilities, such as the creation of virtual environments, implies an effort for the user in order to take benefit
from them. In order to avoid this problem, we are contributing the research community with the EMOTIVE (Elastic Management of Tasks in Virtualized Environments) middleware, which allows executing tasks and providing virtualized environments to the
users without any extra effort in an efficient way.
This is a virtualized environment manager which aims to provide virtual machines that fulfils with the user requirements in terms of software and system capabilities. Furthermore, it supports fine-grained local resource management and provides facilities for developing scheduling policies such as migration and checkpointing.Postprint (published version
