Abstract(s)

The existence of a virtualization layer within the cloud affects the resources optimization and the reduction of requirements of its implementation. In this publication the focus will be the use of jail environments, provided by the FreeBSD Operating System, which present a relevant set of features that can enhance the increase of performance. A set of data collection tests that allows measuring the degree of optimization obtainable in current models of cloud computing, based on the use of hypervisors tests, are presented. These tests proved that the increase in performance and optimization of resources is possible, bringing up the need to adapt the current models of cloud computing for the use of such solutions. However, this increase in performance, leads to a loss of flexibility of the usage of independent operating systems, which is not relevant to the model of cloud computing business.
