We look forward to seeing you in Barcelona!

OpenNebula 2014: Year in Review

It’s been a fully packed year in the OpenNebula project and in the cloud computing field. The community is as healthy as ever and is driving your favourite Cloud Management Platform (CMP) to its consolidation as a real, enterprise-ready and open source alternative to transform datacenters into private clouds.

OpenNebula is really vendor-neutral, there is no hype, just a focus on real-life needs, developing the best technology, and serving our users. We think it is important to clearly state what “open”, “simple”, “scalable”, and “flexible” mean for us. Mostly because, as you well know, terms like “open-” and “open-source” are used by many vendors as a marketing tool to lock you into their own version or distribution of a hyped open-source software.


We are also proud of being counted among the Cloud Computing pioneers. These two papers present the original internal design and architecture of the Eucalyptus and OpenNebula cloud management platforms, the very first two open source CMPs.

With 2014 coming quickly to a close, we’d like to review what this year has meant for the OpenNebula project. You have all the details about the great progress that we have seen for the OpenNebula project in our monthly newsletters.

Solving Real Needs in Innovative Ways

Three major releases were published during this past 2014: 4.6 Carina, 4.8 Lemon Slice and 4.10 Fox Fur. Moreover, three maintenance versions were released to fix bugs and polish features. Several maintenance versions of AppMarket were also released.

One of the most relevant features introduced by 4.6 Carina was the ability to create Federations of several OpenNebula instances, and their subsequent partition into Virtual Datacenters, by bounding a group of users to a set of hardware resources: the OpenNebula provisioning model is now considered mature. Also, Carina brought a new Cloud View Portal and support for OVA imports directly to an OpenNebula cloud.

The focus of 4.8 Lemon Slice was simplicity, with several improvements to the Cloud View portal (an important key in the provisioning model) like the addition of the VDC Admin View, based as well on the simplicity designs of the self service portal. The hybrid model was also extended with support for IBM SoftLayer and Microsoft Azure public clouds, and changes in the OneFlow and OneGate made possible sharing service information among VMs. Virtual Networks underwent a thorough redesign: definitions are no longer restricted to the fixed and ranged model, but rather they can include any combination of ranges to accommodate any address distribution.

4.10 Fox Fur was the latest major release of 2014, and it was a very special one, since it featured a little revolution in shape of vCenter support. It is the first OpenNebula release that allows to automatically import an existing infrastructure, since the new vCenter drivers allow to import Clusters and Virtual Machines from a vCenter installation, significantly smoothing the set up curve. Also, Fox Fur introduced an integrated tab in Sunstone to access OpenNebula Systems support and login token functionality.

We would like to thank to all code contributors and sponsors, and especially to Produban, BlackBerry and Echelon for funding several features this last year through the Fund a Feature program. We look forward to your contributions to code development!.

The New vOneCloud

4.10 Fox Fur brought VMware vCenter support to OpenNebula, and it was the seed for a new product by the OpenNebula Team: vOneCloud, a virtual appliance for vSphere that transforms an existing vCenter deployment into an automated, self-service private cloud in a few minutes. The appliance is based on OpenNebula, every component is fully open-source and has been certified to work in enterprise environments.

vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers, self-service portal, or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. vOneCloud seamlessly integrates with running vCenter virtualized infrastructures, leveraging advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family.

2014 saw the first stable release of vOneCloud, which we believe is going to transform the way numerous VMware-based data centers perform their IT processes.

Interesting right? Try it out, it takes very little time and it is not intrusive. We look forward to your feedback!.

A Vibrant Community of Users

We’ve been rapidly growing our vibrant community of users who are supportive, engaged, and opinionated about the direction of OpenNebula ever since. Many of them have contributed new integrations with other platform components in the data center like IBM Storwize V7000 SANsalt-cloudInfiniband (SR-IOV devices)Bacula, Chef Kitchen.NET API, Nodejs, Cloud-init,  Ansible or The Foreman – just to name a few.

We are proud to confirm that the number of downloads from our repositories continue doubling each year. There are tens of thousands of deployments around the globe and OpenNebula is parked in some of the biggest organizations out there including Industry and Research leaders. This year we performed a new Cloud Architecture Survey to know about the types of OpenNebula cloud deployments and their main architectural components.

We would like to thank all our users! It is out of scope to name all new users, but we want to give a wholeheartedly warm welcome to those new users that shared their experiences through our blog: Runtastic, Avalon, China Mobile, Rentalia and If you are using OpenNebula, we want to hear from you! We look forward to having more details about your deployment and experiences!. You are very welcome to contribute your integrations and experiences by writing a post in our blog or submitting your integration to the OpenNebula Add-on Catalog.

Spreading the Word

Our biggest event in 2014 was undoubtedly the OpenNebula Conf! Held in Berlin, and organized by Netways, at early December.  It featured lots of very interesting users: RedHat, Runtastic, Deloitte… Check out the videos and, more importantly, the amazing feedback gathered by the team from the OpenNebula users. This is what makes OpenNebula unique, it’s down-to-earth, user-driven model.

This year the team was very busy spreading the OpenNebula word in several events. Important events with OpenNebula representation were CeBIT 2014, FLOSS UK 2014, several CentOS Dojos (like for instance this one in Brussels, jointly with Fosdem 2014), CloudScape VI, Cloud Expo Europe, Future Internet Assembly, Closer 2014, EGI Community Forum, GigaOM StructureHostingConLOADays and many, many more! We want everyone at least to have the chance to know about what we think is the easiest to use, most powerful and definitely most enterprise ready open source CMP!.

A series of events crafted by OpenNebula are the OpenNebula TechDays. Probably the most relevant ones this year happened in both US coasts: Florida and San Francisco hosted by TransUnion|TLOxp and Hyve Solutions. Other relevant TechDays took place in Europe: Timisoara by CloudBase and Unified Post, Santiago by Agasol, Ede by, Barcelona by CSUC, Almendralejo by CENATIC… and much more to come in this 2015!.

We want to thank all organizations that hosted a TechDay in 2014 for their amazing hospitality and making these events a success. We are organizing the schedule of TechDays for future months, send us an email or send it to the community discuss mailing list if you are interested in hosting a TechDay event. We also look forward to proposals to create a user group in your area.


We think it is impossible to stress too much or too often the importance of our community. THANK you all (users, developers, integrators, cloud architects, all of you!) for helping us building a great cloud management platform that solves real world problems.

We’d also like to take this opportunity to wish you happiness and prosperity in 2015 to you and your loved ones!.

OpenNebula is 7 Years Old!

Yes, time flies, and it is now time to celebrate the 7th anniversary of In the post we wrote last year to celebrate our sixth anniversary we described the progress of the project in terms of its community, adoption and innovation. We are really proud to confirm that those figures are growing at the same rate.

This year we would like to focus on our commitment to the open cloud. We think it is important to clearly state what “open”, “simple”, “scalable”, and “flexible” mean for us. Mostly because, as you well know, terms like “open-” and “open-source” are used by many vendors as a marketing tool to lock you into their own version or distribution of a hyped open-source software. Well, I think you know what we mean.

  • Openness means you can run production-ready software that is fully open-source without proprietary extensions that lock you in. Yes, this means that OpenNebula does not need enterprise extensions. Yes, OpenNebula is not a limited version of an enterprise software… There is one and only one OpenNebula distribution, and it is truly open-source, Apache licensed, and enterprise-ready. There is no fragmentation.  As recently stated by one of our users:

“Other open-source cloud management platforms do not work out of the box, you need to go through a vendor – they are open source but vendor-based and brings proprietary components”

  • Simplicity means that you do not need an army of administrators to build and maintain your cloud. OpenNebula is a product and not a toolkit of components that you have to integrate to build something functional. Moreover your cloud will run for years with little maintain. As recently stated by one of our users:

“It is easy to bring existing sysadmins to handle OpenNebula since it is just standard components that is used”

  • Flexibility means that you can easily build a cloud to fit into your data center and policies. Because no two data centers are the same, we do not think there’s a one-size-fits-all in the cloud, and we do not try to impose requirements on data center infrastructure. We try to make cloud an evolution by leveraging existing IT infrastructure, protecting your investments, and avoiding vendor lock-in. As recently stated by one of our users:

“OpenNebula captured my interest for several technical reasons besides the fact that it is truly open. It’s architecture is very elegant; it has C++ bones, ruby muscles and bash tendons. It’s extensible and understandable”

  • Scalability means that you can easily grow the size of each zone and the number of zones. Some of our main users have reported infrastructures with tens of zones distributed worldwide that have executed several hundreds of thousands of virtual machines. As recently stated by one of our users:

“Very simple to use, implement and deploy, but yet, you guys make it very scalable and reliable”

Fully embedded in our commitment to the open-source world, we are immersed in a disruptive move, building a bridge between the proprietary virtualization field dominated by VMware and the open source cloud arena. We are doing so with an integration between OpenNebula and vCenter, easy to use and to deploy, bringing cloud features on top of production virtualized infrastructures. VMware users can take a step toward liberating their stack from vendor lock-in. Being OpenNebula a platform independent software, they can gradually migrate to open virtualization platforms.

Looking back, it is inspiring the distance that we have come together. And that is nothing compared to what is planned for the future. We look forward to meeting you in a few days in Berlin in our second OpenNebula Conference, we have a lot to celebrate.

Thanks to all of you and happy anniversary!

OpenNebulaConf2014: Practical experiences with OpenNebula for cloudifying a SaaS by Deloitte’s Tim Verhoeven

Tim Verhoeven, lead architect for a Business Intelligence and Analytics SaaS cloud platform at Deloitte Consultin, will give a keynote entitled “Practical experiences with OpenNebula for cloudifying a SaaS” in the upcoming OpenNebulaConf 2014 to be held in Berlin on the 2-4 of December.

Tim will speak about how his team manages a SaaS platform for Business Intelligence and Analytics applications using a diverse set of middleware (mostly IBM). However the original setup of this platform was not done using a cloud architecture. In this talk they describe the reasons for selecting OpenNebula. The architecture of the new setup. The process of migrating to that new setup and the lessons they learned during that process and in the daily operation of the platform. And finally this talk will also cover their vision for the next step which is to move towards a hybrid cloud setup.

Tim currently works for Deloitte Consulting in Belgium as the lead architect for a Business Intelligence and Analytics SaaS cloud platform. Tim Verhoeven is been involved in IT Infrastructure for more then 10 years and in these years gathered experience with Linux, networking, servers, storage and the tools and processes to deploy, manage and monitor these infrastructures.

Building Clouds on vSphere: vOneCloud vs vCloud Competitive Pricing Review

This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of ten hosts (servers) running vSphere and managed by one vCenter instance. 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 provide your users with a simple cloud interface featuring elasticity, multi-tenancy and self-service provisioning.

This post compares the pricing of two different approaches to build this cloud environment, the deployment of vOneCloud (an open-source replacement for vCloud based on OpenNebula) on your existing vSphere/vCenter environment versus the adoption of VMware vCloud Suite:

  • The latest version of the vCloud Suite (5.8) brings all the components needed to build and manage a vSphere-based private cloud. The three product editions, Standard, Advanced and Enterprise, include vSphere Enterprise Plus and vCloud Director. According to VMware’s official price list, the average cost (including license and support) per server (2 processors) and year (license cost prorated in three years) of vCloud Standard is €4,883.41 and € 5,243.13 for basic and production support level respectively.
  • vOneCloud requires vSphere (Standard edition is enough) and vCenter Standard. According to VMware’s official price list, the average cost (including license and support) per server (2 processors) and year (license cost prorated in three years) of vSphere Standard is €1,087.35 and €1,177.27 for basic and production support level respectively. If we add the cost of vCenter Standard (we consider a cloud consisting of 10 servers), the overall cost per server and year is €1,331.52 and €1,439.44 for basic and production support level respectively. vOneCloud is free, open-source software, and the cost of an enterprise support subscription (we consider a cloud consisting of 10 servers) per server and year is between €100 and €500 for basic and premium support.

This case study reveals savings of more than €3,000 a year per server using vOneCloud over vSphere/vCenter to build the cloud. The saving is much higher if you are using servers with more than 2 processors or building a cloud with more than 10 servers, given that vCloud licensing/support costs are per processor while vOneCloud support costs are per vCenter instance for unlimited number of processors and servers. For example, in infrastructures with 4-CPU servers, savings would be more than €6,000 per server and year. In a private cloud consisting of 10 servers, the saving would be between €30,000 and €60,000 a year.

vCloud defenders will argue that vCloud suite incorporates more features than vOneCloud on top of vSphere/vCenter. However the same arguments could be used in favor of vOneCloud, which offers features for hybrid cloud or federation that are not offered by the vCloud suite (your would require vRealize). In any case, the right cloud tool depends on your specific needs, our experience is that vOneCloud exceeds the cloud management requirements of most users.

The main advantage of vOneCloud is the strategic path to openness as you move beyond virtualization toward a private cloud. Adopting vOneCloud, you take a step toward liberating your stack from vendor lock-in. Being platform independent software, you can gradually migrate to other virtualization platforms. vOneCloud can leverage your existing VMware infrastructure, protecting IT investments, and at the same time avoid future vendor lock-in, strengthening the negotiating position of your company.

Why not give it a try?. The vOneCloud appliance does not interfere in existing vSphere configurations, procedures and workflows. This means that you can try it and if you decide not to adopt it, you can just delete it.

Update: This post was updated on January 2nd 2015 to include the new pricing plans for vOneCloud enterprise support. The new support subscription prices are per vCenter instance for unlimited number of servers.

vOneCloud: The Simplest Alternative to vCloud

We are glad to announce the Beta release of vOneCloud, a CentOS Linux virtual appliance for vSphere that contains all required OpenNebula services optimized to work on existing VMware vCenter deployments. vOneCloud is for companies that want to create a self-service cloud environment on top of their VMware infrastructure without having to abandon their investment in VMware and retool the entire stack. vOneCloud deploys an enterprise-ready OpenNebula cloud just in a few minutes where the infrastructure is managed by already familiar VMware tools, such as vSphere and vCenter Operations Manager, and the provisioning, elasticity and multi-tenancy cloud features are offered by OpenNebula.

vOneCloud is our answer to those companies looking for alternatives to VMware vCloud. They usually report that:

  • vCloud is not an easy to use solution
  • vCloud is mostly suited for vSphere and public clouds running VMware
  • vCloud cannot be adapted to their needs
  • Last, but not least, VMware announced in september 2013 that vCloud Director was approaching end of life for enterprises with its functionality being split into vCenter and vCloud Automation Center



vOneCloud is for companies that want to keep VMware management tools, procedures and workflows. vOneCloud seamlessly integrates running vCenter virtualized infrastructures so leveraging the advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family. On top of it, OpenNebula exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers, datacenter federation or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. You also take a step toward liberating your stack from vendor lock-in.

It is all about simplicity. vOneCloud is extremely simple to install, adopt, update and use. Why do not you give a try to vOneCloud to manage your VMware environment?. We look forward to your feedback.

2014 OpenNebula Cloud Architecture Survey Results

Executive Summary

The results of this survey were collected during July and August of 2014 from the OpenNebula open source cloud management platform community with regards to the type of cloud deployment and its main architectural components. The aim of the survey is to acquire information in order to improve the support for the most demanded infrastructure platforms and deployments.

Since the foundation of the open-source project in November 2007, OpenNebula has been downloaded more than 200,000 times from the project site (120,000 times since our last survey in September 2012), not including other software repositories or third-party distributions.

Regarding the use of OpenNebula, the Survey shows that 42% of the deployments are in Industry and 14% in Research Centers. 74% of the organizations are in Europe, Russia or USA. 88% of the respondents use OpenNebula to build a private cloud. When asked about the type of workload, 62% said that they use OpenNebula for running production workloads.

Regarding the size of the clouds, 10% of the deployments have more 500 physical nodes. 44% of the deployments consist of more than one OpenNebula zone and 4% are running more than 10 zones. One of the companies reported a workload of 200,000 VMs. Among the advanced components offered by OpenNebula, High Availability, with 67%, is the most widely used or planned to use, which is closely aligned with the top usage of OpenNebula in production environments.

Regarding the building blocks of the cloud, KVM at 48% and VMware at 30% are the dominant hypervisors, and CentOS at 46% and Ubuntu at 36% are the most widely used linux distributions for OpenNebula clouds. The preferred choices for the storage back-ends are shared FS and SSH with a 52% and 36% ratio respectively. The most widely used Configuration Management Systems are Puppet and Ansible with a 37% and 14% respectively. Regarding networking, most of the deployments, a 49%, use the Standard Linux Bridge for network configuration, 38% use Open vSwitch, and 30% use 802.1Q.

In comparison to the previous survey findings in 2012, the relevant changes are that CentOS has displaced Ubuntu as the most widely linux distribution to build OpenNebula clouds, and a growth in the number of production deployments from 42% to 62% and in the number of public clouds that has doubled from 21% to 40%.

Although more than 2,000 users took part of the survey, we have only included in the analysis those respondents using OpenNebula 4.x (latest series) and who we deem reliable because they have provided identification details that allow us to verify the answers of the survey. This is important given that our main aim is to have accurate and useful information about OpenNebula deployments.

Last, but not least, when asked about what you like most about OpenNebula, most users, a 76%, answered because of its simplicity, and 69% and 65% answered because of its flexibility and openness. These results are aligned with our our mission — to become the simplest cloud enabling platform — and our purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure.

OpenNebula Integrates with Azure to Build Hybrid Clouds

Today we are sharing exciting news about the expansion of the number of public clouds supported by OpenNebula to build hybrid cloud deployments. As a result of the collaboration between OpenNebula and Microsoft, a new set of plug-ins to support Microsoft Azure has been included in OpenNebula. This partnership has been announced today by Microsoft Open Technologies at the O’Reilly Open Source Convention (OSCON).

“With this set of plug-ins, IT pros and system integrations can use OpenNebula’s rich set of infrastructure management tools to manage cloud deployments across Microsoft’s private, public and hosted cloud platforms.”

The Beta version of  OpenNebula 4.8 bringing the new drivers was released today and is available for testing. The integration has been carried out using the Microsoft Azure SDK for Ruby, which interacts with the Azure REST API, enabling a complete control of the lifecycle of Virtual Machines in a transparent way within an OpenNebula cloud. Thanks to these new plug-ins, private resources can be easily supplemented with resources from Azure to meet fluctuating demands.

So far the only public cloud officially supported by OpenNebula to build hybrid cloud deployments was Amazon AWS. Supporting multiple public cloud providers opens the possibility of defining pre-determined schedule or performance-based policies for the execution of applications in different clouds, that can be fine tuned to achieve an optimal placement in terms of performance and cost. This new support also enables the ability to meet services constraints regarding special functionality offered by a subset of the supported public cloud providers, like for instance high availability.

Need more information? You are welcome to use the OpenNebula community instruments to ask around (for instance, the users mailing list is a good place to pose your questions).

As always, we value your feedback and contributions to this new feature!

New User Survey: Please Help Us Meet Your Needs!

We have created a new user survey that will take you only 5 minutes to complete. As an open-source community, it is very important for us to have information about your deployment. Doing so you will have influence over the project and software direction, and will help us improve the support for most demanded infrastructure platforms and configurations.

All of the information you provide is confidential. We will not share organization-specific or personal information. We will only report aggregate, non-personally identifiable data.

The results from our last survey  (2012) are available here. Do not hesitate to contact us if you have questions.


Thanks for completing the survey!
