RODRIGUEZ-HARO, Fernando; FREITAG, Felix  e  NAVARRO, Leandro. A QoS App-SLO Manager for Virtualized Infrastructure. Polibits [online]. 2012, n.46, pp.83-91. ISSN 1870-9044.

The management of infrastructure for supporting Cloud Computing presents the challenge of automated service provisioning, which addresses the problem of mapping high-level requirements expressed in end-user terms to low-level resources such as CPU, memory, and network bandwidth. Current infrastructure is supported through virtualization via hypervisors. In this paper, we describe the formal specification of a high-level component for enhancing hypervisors. With this component, applications running in a Virtual Machine can receive a Quality of Service defined by Service Level Objectives. The manager is aware of the application's needs and requests the CPU resources through the lifetime of the Virtual Machine. The implementation of our proposal achieves to manage computing-oriented and net-oriented applications.
