The OpenNebula team has just announced the immediate availability of the final version of OpenNebula 4.8, codename Lemon Slice. This release brings significant improvements in different aspects. Sticking with its vision of bringing simplicity to cloud management, there are improvements in the recently added Cloud View portal, designed for end users. One significant advantage of the new portal is the ability to control flows, groups of interconnected Virtual Machines that conform a service. Based on this Cloud View, a Virtual Datacenter administrators view has been included (VDCAdmin View), which enables VDC admins to easily manage the VDC users and resources. An important highlight in this release is the vast improvement made to the hybrid model. Support for two new public cloud providers has been added, widening the range of possibilities to offload VMs in case the ... (more)

The Role of Cloud Computing

Let me show how I see Cloud (and virtualization as enabling technology) and Grid as complementary technologies that will coexist and cooperate at different levels of abstraction in future infrastructures. I will first clearly state my position about Cloud and Grid, which are complementary technologies. There is a growing number of posts and articles trying to show how cloud computing is a new paradigm that supersedes Grid computing by extending its functionality and simplifying its exploitation, even announcing that Grid computing is dead. It seems that new technologies and para... (more)

Building Your Open Source Private Cloud

Ruben S. Montero has published a series of posts in the DSA-research blog on the benefits of virtualizing a distributed infrastructure with the OpenNebula Virtual Infrastructure Engine: In "The Private Clouds", Ruben discusses the motivations for building a private cloud using open-source technology. In "When 8 are 26 (or even more)", he shows a real case of server consolidation using OpenNebula to orchestrate a distributed infrastructure running Xen and KVM nodes In "Elastic Management of Computing Clusters", he describes how to deploy a computing cluster on a virtualized distri...

Interoperation Between Cloud Infrastructures

A Distributed Virtual Infrastructure (VI) Manager is responsible for the efficient management of the virtual infrastructure as a whole, by providing functionality for deployment, control and monitoring of groups of interconnected Virtual Machines (VMs) across a pool of resources. An added functionality of these management tools is the dynamic scaling of the virtual infrastructure with resources from remote providers, so seamless integrating remote Cloud resources with in-house infrastructures. This novel functionality allows to add and remove capacity in order to meet peak or ... (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 science and engineering. The group covers the following aspects about innovative potential, benefits and challenges of new Cloud technologies and services in High Performance Computing (HPC) and ... (more)
