Eficiência energética na consolidação de servidores: uma comparação entre a virtualização e a conteinerização

Abstract

In many scientific and professionals areas the demand for high performance computing resources is ever-increasing because of their extreme importance to obtain the best result in solving increasingly complex problems. In the last decade virtualization has contributed in a decisive way in optimizing computational resources usage, either in private datacenters and cloud-computing service providers. Traditionally dominated by virtual machine technology based on hypervisors, environments that make use of containers for application provisioning have become popular. Once hardware resources being shared there was a significant increase in energy efficiency. On these environments, traditionally dominated by technology virtual machines from hypervisors, the use of containers for application provisioning have become popular in past few years. Considered as a lightweight alternative to hypervisors, containers bring several benefits, such as lower hardware overhead, reduction of configuration-depending failures, simplification of upgrades and greater speed on startup. The steady increase in adoption of this technology is mainly due the evolution of the orchestration tools, Docker as an example, which simplify the process of creation, implementation and management of containers. Considering these aspects, the present study proposes to establish a comparative analysis of consumption and efficiency of applications running in virtualized and containerized environments.
