Análise de tecnologias de virtualização e hardware de baixo custo para infraestutura de nuvem de pequeno porte

Abstract

The increasing demand for services offered in the cloud computing, has caused in recent years investments in the order of millions of reais in the construction and operation of data centers. Aiming to reduce the acquisition and operation costs of these infrastructures, researchers seek to develop alternatives that deliver computing services, in more specific cloud scenarios at lower prices. In this context, this work makes a comparative analysis of the execution of a typical Internet application in traditional virtualisation (Virtual Machine), containerization (Container LXD) and low cost hardware (Raspberry Pi) environments, with the aim of making feasible the use of cheaper hardware arrays for small cloud infrastructures. Thus, with the support of the tools Jmeter and Collectl, resource exhaustion experiments were developed for basic database operations such as write (INSERT), query (SELECT) and delete (DELETE) in the WebTool application. The results revealed that Raspberry Pi is equivalent to 12% of Container LXD with maximum number of concurrent users on the system in DELETE operation. In contrast, in the SELECT operation, Raspberry Pi presented a gain of 6% when compared to Virtual Machine and accounted for 94% of Container LXD. In this way, it was possible to conclude that it is feasible, in small infrastructures, to implement cloud services for typical Internet applications using Raspberry Pi.
