The authors of the widely used OpenNebula toolkit have founded a company to provide value-added enterprise-solutions around this leading open source technology for cloud computing. C12G Labs has been created to address the growing demand for commercial support and services around OpenNebula. "Our experience is that one single cloud solution does not fit all the requirements and constraints from any data center. We provide our partners with technology and services to build their custom cloud solution, product or service", said Ignacio M. Llorente, co-lead of the OpenNebula open-source project and Chief Executive Advisor of C12G Labs. "We are very excited with this new venture that will contribute to the future sustainability of OpenNebula. This open-source cloud-enabling technology will continue being distributed under Apache license and matured through a vibrant co... (more)

Building Clouds on @VMware vSphere | @CloudExpo [#Cloud]

Building Clouds on VMware vSphere This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of multiple hosts running vSphere and managed by one or several instances of vCenter. It is understood that you do not want to abandon your investment in VMware by retooling the entire stack. You want to continue managing your infrastructure with already familiar and powerful VMware tools, such as vSphere and vCenter Operations Manager. Your goal is to create a self-service cloud environment on top of your vSphere infrastructure to pro... (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)

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)
