Balanceamento de carga de servidores virtualizados

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.
