Samsara: uma Arquitetura Ciente de Situação para Gerenciamento de Infraestruturas em Nuvens Computacionais

Abstract

Cloud Computing is a distributed computing paradigm that focus in promoting the reduction of operating costs by optimizing the use of computational resources, concentrating the administration and management efforts of these resources and their infrastructure in a single provider capable to provide computing infrastructure, development platform, and application software in the form of highly scalable, dynamic and delivered on demand services. Concerns about energy efficiency in computing environments go beyond issues related to reducing the financial cost of its maintenance. Currently, there is also strong motivation to reduce the environmental impact linked to the use of computing resources, particularly for the carbon dioxide emissions of power generation sources. In a scenario as described, it is understood that initiatives to promote efficient management of resources that support the Cloud Computing meets the expectations of the Green Computing as reducing the environmental impact of the development of computer systems and leveraged for growth. This work presents an architecture for resource management infrastructure of a cloud computing considering the use of loads and power consumption, which employs Situation Awareness as a strategy to qualify the mechanisms of management of complex computing environments such as Computer Cloud. Its architecture explores the ability to develop systems aware of their states and able to make decisions and act in autonomic form an efficient management of resources that support Cloud Computing, aiming to contribute to the care of expectations of Green Computing as reducing the environmental impact of the development of computer systems. During the evaluation, the environment managed by Samsara presented energy consume reduction up to 12.3 % for some workloads.
