Resumen
Cloud Computing se enfoca en tres categorías como son IaaS, PaaS y SaaS, mediante el uso de recursos virtuales que permiten la transición entre arquitecturas de red tradicional a arquitecturas de virtualización cumpliendo caracteristicas de flexibilidad, disponibilidad, confiabilidad, escalabilidad y portabilidad. Este estudio se centra en la categoría IaaS mediante el análisis de disponibilidad de varios modelos de equipos de red que hacen parte de la Infraestructura de datacenter tradicional de un carrier de comunicaciones, el análisis de disponibilidad se realizó en cinco modelos de equipos con mayor índice de fallas, igualmente se implementó un escenario de laboratorio de Cloud Computing IaaS donde se configuró un componente de virtualización de Servers y un Componente de virtualización de hardware de networking para virtualizar cada uno de los modelos de equipos considerados en la muestra de estudio. De acuerdo con los resultados en los equipos físicos, el modelo 3 es el equipo que presentó menor carga de CPU cuando se dio la saturación de tráfico, el Modelo 1 presentó una indisponibilidad del 32% y el Modelo 4 del 56%, los Modelos 2 ,3 y 5 tuvieron una disponibilidad del 100%. Los resultados en los equipos virtualizados, muestran que el estado de salud de los dispositivos virtualizados tiende a reducirse a medida que hay mayor saturación, esto debido a la falta de un hypervisor en la configuración del ambiente virtualizado, el modelo 2 presenta el mejor comportamiento en CPU, mientras que en el modelo 5 a mayor saturación de tráfico la CPU se consume por completo viéndose afectado el estado de salud del dispositivo, con una indisponibilidad del 100%.
Abstract. Cloud Computing focuses on three categories such as IaaS, PaaS and SaaS, by using virtual resources that allow the transition between traditional network architectures to virtualization architectures fulfilling characteristics of flexibility, availability, reliability, scalability and portability. Cloud Computing focuses on three categories such as IaaS, PaaS and SaaS, by using virtual resources that allow the transition from traditional network architectures to virtualization architectures. This study focuses on the IaaS category by analyzing availability of several models of network equipment that are part of the traditional datacenter infrastructure of a communications carrier, the availability analysis was conducted in five equipment models with the highest faults record, also was implemented a Cloud Computing laboratory where was configured a server virtualization component and a networking hardware virtualization component to virtualize each device models considered in the study sample. According to the results in the physical equipments, the equipment model 3 had the most lowest CPU load when the traffic saturation occured, the equipment model 1 had an unavailability of 32% and the equipment model 4 had an unavailability of 56%, the equipment models 2,3 and 4 had a availability of 100%. The results in the virtualized equipment models show that the health of devices tends to decrease as no greater traffic saturation, this due to lack of a hypervisor in the configuration of virtualized environment, the equipment model 2 presents the best performance in CPU, while the equipment model 5 to highest traffic saturation affect the CPU performance and it is completely consumed being affected the health of the device, with an unavailability of 100%.
