OpenNebula Included in First StratusLab Release

The StratusLab project has just released the first version of its cloud computing distribution, which aims to provide a full cloud solution for grid and cluster computing. The StratusLab distribution, which includes OpenNebula as the core virtual machine manager and cloud management tool, is being tested on research grid infrastructures, which are composed of dozens of sites and comprises tens of thousands of physical hosts. The first version of the StratusLab distribution is a technology preview, and not yet production-ready, but it will give system administrators and users a chance to try out the new features of what will become an integrated solution for cloud management, running grid services within the cloud, and accessing cloud resources and services from the Grid.

Funded through the European Union Seventh Framework Programme (FP7), the two-year StratusLab project aims to integrate ‘cloud computing’ technologies into ‘grid’ infrastructures. Grids link computers and data that are scattered across the globe to work together for common goals, whilst cloud computing makes software platforms or virtual servers available as a service over the Internet, usually on a commercial basis, and provides a way for organisations to access computing capacity without investing directly in new infrastructure. Linking grid and cloud technologies will result in major benefits for European academic research and is part of the European Commission strategy to develop European computing infrastructures.

Cfengine and OpenNebula for automated clouds

If you’re a system administrator, you’ve probably already heard of Cfengine, a cross-platform datacenter automation framework used by more than 5,000 companies on millions of machines worldwide. With Cfengine, the sysadmin describes the desired system state and Cfengine takes care of the rest: it will install packages, maintain configuration files, keep permissions and ensure the right processes are running according to your policy.

The Cfengine team has been investigating how Cfengine may be used on both the physical and virtual sides of an OpenNebula-based cloud. More specifically, we have been looking into how Cfengine can be used to install and configure the physical infrastructure in an OpenNebula cloud, followed by the launch and configuration of generic virtual machine images that will run on top of that OpenNebula infrastructure.

This week, at the Large Installation System Administration (LISA) conference in San Jose, we will give a brief overview of the possibilities of a Cfengine-managed OpenNebula setup. If you can’t make it to our talk, during the Cfengine BoF (Tuesday, November 9th, 7pm-8pm), you can check out the slides from our presentation here.

OpenNebula in the EU Initiative to Integrate Cloud with Grid

Researchers from a collaboration of six European organisations have attracted funding worth €2.3million to develop a new Internet-based software project called StratusLab. The two year project, headed up by Project Coordinator Dr Charles Loomis from CNRS, was launched in Paris on the 14th of June 2010. It aims to enhance distributed computing infrastructures, such as the European Grid Infrastructure (EGI), that allow research and higher education institutes from around the world to pool computing resources.

Funded through the European Union Seventh Framework Programme (FP7), the two year project aims to successfully integrate ‘cloud computing’ technologies into ‘grid’ infrastructures. Grids link computers and data that are scattered across the globe to work together for common goals, whilst cloud computing makes software platforms or virtual servers available as a service over the Internet, usually on a commercial basis, and provides a way for organisations to access computing capacity without investing directly in new infrastructure. Behind cloud services are data centres that typically house large numbers of processors and vast data storage systems. Linking grid and cloud technologies will result in major benefits for European academic research and is part of the European Commission strategy to develop European computing infrastructures.

StratusLab will integrate, distribute and maintain a sustainable open-source cloud distributionto bring cloud to existing and new grid sites. The StratusLab toolkit will be composed of existing cutting edge open source software, and the innovative service and cloud management technologies developed in the project. The StratusLab toolkit will integrate OpenNebula, the leading open-source toolkit for cloud computing. OpenNebula is a cloud management tool that is widely used in several grid and HPC sites.

Speaking about the project, Project Coordinator Dr Charles Loomis said: “Computer grids are used by thousands of researchers in many scientific fields. For example, the data from the Large Hadron Collider’s experiments, the world’s largest and highest-energy particle accelerator situated at CERN in Switzerland, are distributed via an international grid infrastructure to be processed at institutes around Europe and the world. The StratusLab toolkit will make the grid easier to manage and will allow grids to tap into commercial cloud services to meet peak demands. Later it will allow organisations that already provide a grid service to offer a cloud service to academic users, whilst retaining the many benefits of the grid approach.”

The StratusLab project will bring several benefits to the distributed computing infrastructure ecosystem including simplified management, added flexibility, increased maintainability, quality, energy efficiency and resilience of computing sites. It will benefit a wide variety of users from scientists, who can use the systems to run scientific analyses, to system administrators and hardware technicians, who are responsible for running grid services and maintaining the hardware and infrastructure at various resource centres.

The StratusLab project brings together six organisations, all key players with recognised leadership, proven expertise, experience and skills in grid and cloud computing. This collaboration presents a balanced combination of academic, research and industrial institutes with complementary capabilities. The participating organisations include the Centre National de la Recherche Scientifique (CNRS), France; the DSA-Research Group at Universidad Complutense de Madrid, Spain; the Greek Research and Technology Network S.A., Greece; SixSq Sárl, Switzerland; Telefonica Investigacion y Desarrollo, Spain, and Trinity College Dublin, Ireland.

Building Hybrid Clouds with OpenNebula and Deltacloud

OpenNebula has just released a Deltacloud adaptor to build Hybrid Clouds. A Hybrid Cloud is an extension of a Private Cloud to combine local resources with resources from one or several remote Cloud providers. The remote provider could be a commercial Cloud service or a partner private infrastructure running a different OpenNebula instance. Hybrid Cloud computing functionality enables the building of cloudbursting and cloud federation scenarios.

OpenNebula provides support for building Hybrid Clouds with Amazon EC2 and ElasticHost, and now with this new adaptor OpenNebula leverages RedHat Deltacloud to access any major public cloud, such as GoGrid, Rackspace, Terremark or RimuHosting and Private clouds running OpenNebula or RHEV-M.

A single OpenNebula management instance can be used to combine local infrastructure with multiple remote clouds, so building a highly scalable hosting environments. OpenNebula provides support for building any type of Cloud architecture thanks to its support for most popular interfaces (VMware vCloud, Amazon EC2 and OGF OCCI) on more used hypervisor (Xen, KVM, and VMware) and now with on-demand acess to any major public cloud.

OpenNebula Implements vCloud Express API

OpenNebula has contributed to its ecosystem a new Cloud Service to access OpenNebula clouds through the vCloud Express API.  The OpenNebula vCloud Service is a web service that enables you to launch and manage virtual machines in your OpenNebula installation through the vCloud Express API. The vCloud web service is implemented upon the new OpenNebula Cloud API (OCA) layer that exposes the full capabilities of an OpenNebula private cloud; and Sinatra, a widely used light web framework. The vCloud Express API in which this implementation is based, is the one specified by Terremark. This API consists of a subset of standard vCloud API calls that have been customized for a Terremark installation as well as Terremark-specific API calls. The new vCloud service has been tested to work with the vCloud drivers of libcloud and Red Hat deltacloud.

With this new cloud service, OpenNebula implements most common Cloud interfaces: Amazon EC2 Query, OGF OCCI and VMware vCloud. Besides theses interfaces, OpenNebula also brings libvirt and a powerful CLI, and all of them can be used on the same OpenNebula instance, so users can use their favorite interface. Moreover all those interfaces can be used on any of the virtualization technologies supported, Xen, KVM and VMware. These unique features confirm OpenNebula as the leading open-source technology for cloud computing, and demonstrate its adaptability and extensibility capabilities that many enterprise IT shops need for internal cloud adoption.
