IaaS Cloud Architecture: From Virtualized Datacenters to Federated Cloud Infrastructures


"IaaS Cloud Architecture: From Virtualized Datacenters to Federated Cloud Infrastructures"  is the title of our last article published in the December 2012 issue of the IEEE Computer Magazine that presents an architecture reference model for IaaS clouds. The article introduces the cloud OS (Operating System) platform as the core component of this architecture that is responsible for managing the physical and virtual infrastructure, orchestrating and commanding service provisioning and deployment, and providing federation capabilities for accessing and deploying virtual resources in remote cloud infrastructures. The article ends with a description of different architectures for cloud federation. OpenNebula is also mentioned as an open-source reference implementation of the cloud OS platform.

Enjoy the article!
