Ubuntu 9.04 (Jaunty Jackalope) has been released today bringing highly interesting new features, specially in the Cloud Computing and Virtualization area. The new Ubuntu server distribution includes two complementary cloud tools, OpenNebula and Eucalyptus, so providing the technology required to build the three types of Cloud architectures, namely private, hybrid and public clouds. Eucalyptus can be used to transform an existing infrastructure into an IaaS public cloud, being compatible with Amazon’s EC2 interface. Eucalyptus is fully functional with respect to providing cloud-like interfaces and higher-level cloud functionality for security, contextualization and image management. OpenNebula, on the other hand, is a virtual infrastructure engine that enables the dynam... (more)

Interfacing Private Clouds with the libvirt Virtualization API

In my post "Interfaces for Private and Public Cloud Computing", I briefly described the main differences between public and private cloud computing from the perspective of their different application scope and interfaces. My position was that a private cloud interface should provide rich enough semantics, far beyond of that provided by public clouds (such as Amazon EC2 APIs), to ease the... (more)

High Performance and Grid Computing in the Cloud

The HPCcloud discussion group has been created in order to address the growing interest in High Performance Computing and Grid Computing in the Cloud. The purpose of this group is to present experiences and scenarios by individuals, organizations and projects to illustrate how Cloud computing can enhance the different types of distributed and high performance computing infrastructures in...

Europe’s Largest Grid Project Moves Closer to Cloud-style Computing

The integration of two clans of computation, ‘grid’ and ‘cloud’ computing, is moving closer through collaboration between the projects Enabling Grids for E-sciencE (EGEE) and  Resources and Services Virtualisation without Barriers (RESERVOIR). The two teams will work together to explore how the institutes providing computing resources to EGEE could benefit from adopting a ‘private cloud’ ... (more)

OpenNebula Implements the OGF Open Cloud Computing Interface Draft Spec

Last Friday, the OpenNebula project announced the implementation of the OGF OCCI draft specification.  The release, that will be part of OpenNebula 1.4,  includes a server implementation, clients command for using the service and enabling access to the full functionality of the OCCI interface, and several supporting documents. The last version of this open source toolkit for cloud compu... (more)
