El modelo de despliegue de Nube Privada, perteneciente al paradigma de la computación en la nube, constituye para la mayoría de las pequeñas y medianas empresas una solución costo-efectiva-segura para satisfacer ágilmente la demanda de infraestructura de computación. Su adopción hoy se ve frenada debido a la carencia de métodos que permitan afrontar el diseño de nubes privadas bajo las perspectivas del negocio; y los altos requerimientos de cómputo que como mínimo imponen las soluciones comerciales con mayor presencia en el mercado, en relación con los bajos requerimientos de recursos de cómputo que presentan estas entidades para el soporte de los servicios de las tecnologías de la información y las comunicaciones que requieren para cumplir con su misión y hacer realidad su visión; todo lo cual puede originar impactos económicamente negativos. El presente trabajo muestra un estudio del estado del arte referente al tema evidenciando la problemática expuesta.

Operating system level virtualization is a technology that has recently emerged into the cloud services paradigm. It has the advantage of providing better performance and scalability than para-virtualized or full virtualization hypervisors. This solution is getting acceptance into cloud infrastructures. Nowadays public cloud Infrastructure as a Service providers offer applications based in Docker containers deployed on virtual machines. Only a few bring Infrastructure as a Service on a bare metal container infrastructure. In the private cloud scenario, however, it hasn't had a wide acceptance. Private cloud managers, like OpenStack, OpenNebula and Eucalyptus, don't offer good support for it. OpenNebula is a flexible cloud manager, which has been gaining a lot of market over the last years, so it seemed a good idea to strengthen the operating system virtualization support in this cloud manager. This will contribute to achieve better interoperability, performance and scalability in OpenNebula clouds. Therefore, the objective of the present work was to implement a driver to support Linux Containers for OpenNebula. The driver has several features such as: the ability to deploy containers on File Systems, on Logical Volume Managers and on Ceph; it's able to attach and detach network interface cards and disks while the container is on; and it's able to monitor and limit container's resources usage.
