OpenNebula Position on OpenStack Announcement

As many of you know, a new open-source cloud platform, OpenStack, was recently announced. Here at OpenNebula, we think this is a very exciting development in the cloud community, and we’re glad to see so many major players coalescing around an open-source solution. However, we have also been concerned by the all the high-profile announcements and opinion pieces that describe OpenStack as the first initiative for the definition of an open architecture for IaaS cloud computing and a “real” open-source project, criticizing some existing open-source cloud projects as being “open-core” closed initiatives (in some cases conflating “open-core” with “having an Enterprise edition”), and pointing out their lack of extensibility and inability to efficiently scale to manage tens of thousand of VMs. This is the reason why we have decided to write this post in order to clearly state our position in order to avoid misunderstandings, particularly with our growing community of users.

OpenNebula is and always will be 100% Apache-licensed Open-Source Software

OpenNebula was first established as a research project back in 2005, with  first public release in March 2008. We have a strong commitment with open-source, being one of the few cloud management tools that are available under Apache license. The Apache license allows any Cloud and virtualization player to innovate using the technology without the obligation to contribute those innovations back to the open source community (although we encourage that this work be contributed back to the community). This is the case for many third-party commercial products that embed OpenNebula.

OpenNebula is NOT “Open Core”

C12G Labs is a new start-up that has been created to provide the professional integration, certification and technical support that many enterprise IT shops require for internal adoption and to allow the OpenNebula project to not be tied exclusively to public financing (research grants, etc.), contributing to its long-term sustainability. Although C12G Labs does provide an Enterprise edition of OpenNebula, all software extensions and patches created by C12G (distributed in the Enterprise Edition of OpenNebula to support customers and partners) are fully contributed back to OpenNebula and its ecosystem under an OSI-compliant license. So OpenNebula is NOT a feature or performance limited edition of the Enterprise version. C12G Labs contributes to the sustainability of the community edition and is committed to enlarge the OpenNebula community. C12G Labs dedicates an amount of its own engineering resources to support and develop OpenNebula and so to maintain OpenNebula’s position as the leading and most advanced open-source technology to build cloud infrastructures.

OpenNebula is an Open-Source Community

The OpenNebula technology has matured thanks to an active and engaged community of users and developers. OpenNebula development is driven by our community in order to support the most demanded features and by international research projects funding OpenNebula in order to address the demanding requirements of several business and scientific use cases for Cloud Computing. We have also created the OpenNebula ecosystem where related tools, extensions and plug-ins are available from and for the community.

OpenNebula is a Production-ready and Highly-scalable Technology

OpenNebula is an open-source project aimed at developing a production-ready cloud management tool for building any type of Cloud deployment, either in scientific or in business environments. OpenNebula releases are tested to assess its scalability and robustness in large scale VM deployments, and under stress conditions. Of course, you don’t have to take our word for it: several users have reported excellent performance results to manage tens of thousands of VMs. We have been encouraging some of these users to write on our blog about their experiences with OpenNebula. So far, you can read this recent blog post on how OpenNebula is being used at CERN, with more user experiences blog posts to follow soon.

OpenNebula is a Flexible and Extensible Toolkit

Because two datacenters are not the same, OpenNebula offers a open, flexible and extensible architecture, interfaces and components that fit into any existing data center; and enable its integration with any product and service in the Cloud and virtualization ecosystem, and management tool in the datacenter. OpenNebula is a framework, you can replace and adapt any component to efficiently work in any environment.

OpenNebula is Hypervisor Agnostic and  Standards-based

OpenNebula provides an abstraction layer independent from underlying services for security, virtualization, networking and storage, avoiding vendor lock-in and enabling interoperability. OpenNebula is not only built on standards, but has also provided reference implementation of open community specifications, such us the OGF Open Cloud Computing Interface. OpenNebula additionally leverages the ecosystems being built around most popular cloud interfaces, Amazon AWS, OGC OCCI and VMware vCloud

OpenNebula Implements an Open Architecture Defined by Major Players in the Cloud Arena

OpenNebula is the result of many years of research and the interaction with some of the major players in the Cloud arena. This technology has been designed to address the requirements of business use cases from leading companies in the context of flagship international projects in cloud computing. The main international project funding OpenNebula is RESERVOIR. OpenNebula is an implementation of the IaaS management layer of the RESERVOIR open architecture defined by its partners: IBM, Telefonica Investigacion y Desarrollo, University College of London, Umeå University, SAP AG, Thales Services SAS, Sun Microsystems Germany, ElsagDatamat S.p.A,  Universidad Complutense de Madrid, CETIC, Universita Della Svizzera italiana, Universita degli Studio di Messina,  and the European Chapter of the Open Grid Forum. The outcome of this collaboration is the unique functionality provided by OpenNebula.

OpenNebula will Continue Incorporating State-of-the-Art Features Demanded by Major Players

OpenNebula is used, together with other software components, in new international innovative projects in Cloud Computing. StratusLab with the participation of  Centre National de la Recherche Scientifique, Universidad Complutense de Madrid,  Greek Research and Technology Network S.A., SixSq Sárl, Telefonica Investigacion y Desarrollo and Trinity College Dublin, aimed at bringing cloud and virtualization to grid computing infrastructures. BonFIRE with the participation of Atos Origin, University of Edinburgh, SAP AG,  Universitaet Stuttgart, FRAUNHOFER, Interdisciplinary Institute for Broadband Technology,  Universidad Complutense de Madrid, Fundacio Privada I2CAT, Hewlett-Packard Limited, The 451 Group Limited, Technische Universitaet Berlin, IT-Innovation, and Institut National de Recherche en Informatique et en Automatique, aimed at designing, building and operating a multi-site cloud-based facility to support research across applications, services and systems targeting services research community on Future Internet;. And many others, such as 4CaaSt with the participation of UPM, 2nd Quadrant Limited, BonitaSoft, Bull SAS, Telefónica Investigación y Desarrollo, Ericsson GMBH, FlexiScale, France Telecom, Universitat St Gallen, ICCS/NTUA, Nokia Siemens Networks, SAP AG, Telecom Italia, UCM, Universitaet Stuutgart, UvT-EISS, and ZIB, aimed at creating an advanced PaaS Cloud platform which supports the optimized and elastic hosting of Internet-scale multi-tier applications.

All that said, we’d like to reiterate that we strongly support initiatives like OpenStack. This open source initiative is fully aligned with our vision on what the cloud ecosystem should look like, and we will be happy to contribute to OpenStack with our significant track record in open source and scalable cloud computing management, and with an implementation of  the open APIs that will be defined in the context of the OpenStack architecture. However, we felt that some of the buzz surrounding OpenStack unfairly characterized existing open source efforts, and felt it was necessary to reiterate our commitment to an open source cloud ecosystem.

OpenNebula Cloud Announcement

The OpenNebula Team is proud to announce the dawn of the OpenNebula Cloud. Although this can be shortened to ONE Cloud, it is in fact two, although both of them are accesible using two interfaces: OCCI and EC2.

  • Dummy cloud. This cloud offers an interface to an OpenNebula instance configured using dummy drivers. This means that it will offer a seemingly infinite capacity to run VMs, but it actually won’t ever run any VM instance. This ‘dummy’ cloud is offered to test the OCCI and EC2 inte rfaces
  • Real cloud. The OpenNebula instance that supports this clouds has access to physical server, and will offer the possibility of configure virtual networks, launching real VMs and access them using public IPs. This ‘real’ cloud VMs will have a limited capacity and is not meant to provide VMs on demand for personal uses, but rather to test OpenNebula cloud functionality.

The aim of these clouds is to allow for interface testing and foster the creation of an ecosystem built on top of OpenNebula clouds.

More information on configuration of the clients and usage of the two clouds can be found here.

OpenNebula Wins the Best Demo Award at OGF25/4th EGEE-UF

We are happy to announce that our demo “Scaling out EGEE sites on Amazon EC2 with OpenNebula” has won the best demo award in the 4th EGEE User Forum/OGF 25 and OGF Europe’s 2nd International Event. The demos were evaluated by the EGEE External Advisory Committee.

The demonstration showed how virtualization can be used to transform a physical cluster into a flexible and elastic virtual infrastructure, separating resource provisioning from job execution management, and supporting the dynamic adaptation of a virtual EGEE site to the users’ computational demands. The virtual infrastructure, managed by the OpenNebula Virtual Infrastructure Engine, ran on local and Cloud resources, so automatically scaling out the local infrastructure in order to meet peak demands. This demo shows how Grid and Cloud are complementary technologies that will coexist and cooperate at different levels of abstraction in future e-infrastructures. In this particular use case, clouds help to overcome many of the barriers to grid adoption. GridCast recorded a video with the demo.

OpenNebula 1.2 for Data Center Virtualization & Private Cloud Computing

The OpenNebula team is happy to announce 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.

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 the only tool able to access on-demand to Amazon EC2 to dynamically scale the local infrastructure based on actual usage. OpenNebula also exhibits an open and flexible architecture which allows the definition of new algorithms for virtual machine placement, and its integration with any virtualization platform, infrastructure cloud offering and third-party component in the cloud ecosystem, such as cloud-like remote interfaces, virtual image managers, and service managers. OpenNebula is one of the components being enhanced in the context of the European Union’s Reservoir Project, which aims to develop the open source technology to enable deployment and management of complex IT services across different administrative domains.

New Features and Highlights in OpenNebula 1.2

OpenNebula 1.2 presents important improvements in the following areas:

  • Image Management. OpenNebula 1.2 features a general mechanism to transfer and clone VM images. The new Transfer Manager is a modular component that embrace the driver-based design of OpenNebula, so it can be easily extended and integrated with third-party developments and virtually any cluster storage architecture. The new TM allows you to re-use VM images as you can mark them as clonable, and also you can save space as swap images are now created on-the-fly by OpenNebula.
  • Networking. With OpenNebula 1.0 it is difficult to track the MAC/IPs in use by the running VMs, and its association with physical networks. This mechanism does not scale when dealing with tens of VMs. The new Virtual Network Manager module allows you to define virtual networks and it leases IP-MAC pairs to VMs, so you do not have to keep track of the addresses in use. In this way it is pretty much like an embedded DHCP server. Additionally, the leases are built in such a way that you can easily obtain the IP form the MAC when booting the VM. OpenNebula 1.0 networking is still supported, in case you do not want to use the new functionality.
  • Robustness and scalability, OpenNebula 1.2 has been tested in the management of hundreds of running VMs to ensure that the code meets production level requirements.

Getting OpenNebula 1.2

The complete source tree for OpenNebula can be freely downloaded. Additionally the ubuntu virtualization team have kindly provided binary packages for Ubuntu 9.04 (Jaunty Jackalope).
