Abstract
The computational power present in servers today typically is not fully used by its
services. Concerns about security have led administrators to designate fewer services
for each server, ending up with under-used servers. Virtualization is a way to solve this
problem, providing a good way to get the isolation of services and the opportunity to better
use the hardware devices. In environments that use virtual machines to run services, the
distribution of the virtual machines on real servers is usually manually made by the system
administrator, generally in a static way, even if for some reason a real server becomes
more loaded than the others. This has become a problem for administrators, who must
initialize the virtual machines observing various aspects such as memory consumption,
the CPU time used, disk and network usage. This work proposes the development of a
system that automatically balances the load of real servers, monitoring the resources of
actual servers, and improving their usage.
