10:30 – 11:00: Hybrid Clouds: Dancing with Virtual Machines

Jordi Guijarro, CSUC Today, the model of hybrid cloud comes under the eyes of a lot of organizations. The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer. The case of CSUC, acting as cloud provider and at the same time as user of external IaaS and PaaS services, is analyzed sharing its first experiences in the way to archive a real multicloud architecture to provide services for catalan universities and research institutions.
