Time flies, and we are approaching the end of another successful year at OpenNebula!. We've had a lot to celebrate around here during 2012, including our fifth anniversary. We took that opportunity to look back at how the project has grown in the last five years. We are extremely happy with the organic growth of the project. It's five years old, it's parked in some of the biggest organizations out there, and that all happened without any investment in marketing, just offering the most innovative and flexible open-source solution for data center virtualization and enterprise cloud management. An active and engaged community, along with our focus on solving real user needs in innovative ways and the involvement of the users in a fully vendor-agnostic project, constitute, in our view, the OpenNebula's recipe to success. As 2012 draws to and end, we'd like to review wh... (more)

Grids and Cloud as Complementary Computing Paradigms

This is the title of the new GridBriefing just released by GridTalk to introduce Grids and Clouds as complementary computing paradigms. A clear understanding of their relationship will help the development and efficient use of existing academia and commercial e-infrastructures. It is especially interesting the table comparing Grid and Clouds side by side, as well as the strategy recommended in the chapter devoted to Grids and Clouds of the new white paper by the e-Infrastructure Reflection Group to ensure a healthy future for European e-infrastructures: Investigate the integrati...

OpenNebula 1.2 for Data Center Virtualization & Private Cloud Computing

We have just announced the availability of OpenNebula 1.2, the second stable release of the project. This is an important milestone for the project and marks that most of the components of OpenNebula are now in place. See this post with the details of the first release. What is OpenNebula? The OpenNebula virtual infrastructure engine provides efficient, dynamic and scalable management of groups of interconnected VMs within datacenters involving a large amount of virtual and physical servers. OpenNebula supports Xen and KVM platforms and can interface with remote cloud sites, being... (more)

BoF Session on Cloud Computing API at Open Grid Forum 25

A BoF ("birds of a feather") session on Cloud Computing API was organized at Open Grid Forum 25 in Catania (Italy). The session focused on the charter and the creation of a Group inside OGF to work on the development of an API specification for the dynamic deployment, using an appropriate descriptor language, control and monitor of virtual machines. The scope of the specification will be all the high level functionality required for the life-cycle management of virtual machines which is needed to support automated service elasticity. The new specification will facilitate the in... (more)

Interfaces for Private and Public Cloud Computing

An entire ecosystem is evolving around cloud computing. Interface standardization efforts, commercial products, cloud infrastructure and management services, virtual appliance providers and open-source solutions are filling niches in the cloud ecosystem. The role and position of a component or a service in the ecosystem are defined by its capabilities, the consumers of those capabilities and its relationship with other components and services. This article presents public and private cloud computing from the perspective of their different application scope and interfaces. Interfa... (more)
