"Challenges in Hybrid and Federated Cloud Computing" is the title of the keynote about the future of cloud computing that I am giving tomorrow July 7th at HPCS2011 and on the 31th of August at ParCo2011. The keynote describes the different cloud federation scenarios, ranging from a federation built on commercial cloud providers that offer no real support for federation to one built on data centers of the same organization where the sites are completely dedicated to supporting all aspects of federation. The level of federation is defined based on the amount of information disclosed and how much control over the resources is provided across sites. The keynote also presents the existing challenges for interoperability in federated and hybrid cloud computing scenarios, and ends with real-life examples of multi-cloud environments running OpenNebula.
Would be great to meet you at these venues!.
