Abstract:
In the virtualized data center, load
imbalances and the deviation of service level
agreements of the application can occur when the
load changes dynamically over time. This paper
presents Libra, four- level resource management
system which consists of application level
controllers (ALC), virtual machine level controllers
(VLC), host level controllers (HLC) and a center
level controller (CLC). ALC, VLC and HLC
automates the task of monitoring, detecting load
unbalancing, resource managing.CU determines a
new mapping of physical and virtual resources and
initiating the necessary migrations. The four-level
resource controllers use rule-based fuzzy logic for
resource management and migration decisions.
