OpenNebula 5.4 Beta is just around the corner! Codenamed Medusa, OpenNebula 5.4 is the third release of the OpenNebula 5 series. A significant effort has been applied in this release to stabilize features introduced in 5.2 Excession, while keeping an eye in implementing those features more demanded by the community.

As usual almost every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components. An important focus has been on the vCenter integration, with an enhanced network and storage management.

A new resource to implement affinity/anti affinity VM-to-VM and Host-to-Host has been added to OpenNebula, the VM Groups. A VM group is a set of related virtual machines that may impose placement constraints based on affinity and anti-affinity rules.

To top it all, OpenNebula 5.4 brings to the table a native implementation of a consensus algorithm, which enables the High Availability deployment of the OpenNebula front-end without relying to third party components. This new functionality of distributed system state is also used to implement OpenNebula federation.

There are many other improvements in 5.4:

  • like improved VM lifecycle
  • flexible resource permissions
  • live disk resizing
  • improved Ceph support
  • enhanced disk I/O feedback
  • showback cost estimate in Sunstone
  • flexible IPv6 definition
  • http proxy support for marketplace
  • purge tools for the OpenNebula database
  • resource group isolation
  • user inputs in OneFlow

and many many more features to enrich your cloud experience! We’ll appreciate any feedback about the 5.4 Beta to iron out possible issues prior to the upcoming stable release.

Maintaining an OpenNebula addon is not an easy task, but it is a crucial one for the success and widespread adoption of a third party component. Keeping up to date, and tested, against the latest OpenNebula version is of paramount importance to ensure its use by OpenNebula users. We want to bring you attention over the expertly crafted LXDoNe, and addon to enable OpenNebula on the management of LXD Containers. LXD is a daemon which provides a REST API to drive LXC containers. Containers are lightweight OS-level Virtualization instances, they behave like Virtual Machines but don’t suffer from hardware emulation processing penalties by sharing the kernel with the host.

Our friends at Comsysto have published a very interesting article on how to build a Private Cloud infrastructure with OpenNebula. This efforts are very important for the community since they spread the word and help to present what OpenNebula is about under other perspectives, enriching the ecosystem.

With OpenNebula we can build a simple and robust infrastructure that is focused on users needs and not on vendor specifics. Upon basic setup, user’s can already benefit from the installation because OpenNebula enables the user to be self-sustained and not to depend on System administrator or vendor to create and manage their VM’s. It is easily scalable and it can be installed on top of most hardware.

It is also very satisfying to learn how fellow developers chose OpenNebula to build their Continuous Integration infrastructures, like this fine article by the Qt folks.

Two thumbs up to all the OpenNebula advocates that support new OpenNebula users (or more seasoned users) in our support forum and in the IRC channel at freenode (#opennebula). You are a great asset to this project!

We do our best to review and incorporate those PRs aligned with the OpenNebula roadmap. We are grateful for the numerous contributions that help stabilize and enhance the OpenNebula software.

Outreach

The first US edition of the OpenNebulaConf is due in two weeks! Specifically, this June 19-20 in Cambridge, Massachusetts. There are a few places left if you are willing to attend, but you should register fast! The european edition will be held in Madrid, Spain, on October 23-24.

We had three very successful OpenNebula TechDays this past month of May. The first one was based in Madrid and hosted by Telefonica, featuring interesting talks about the use of OpenNebula in large enterprises. The TechDay in Sofia hosted by StorPool was oriented to integrations and interesting use cases on top of OpenNebula. The Barcelona TechDay hosted by CSUC, with a great turnout, was focused to the usage of OpenNebula in academic fields to foster research. Thanks a lot to those who came to the TechDays and for the organizers for hosting them!

OpenNebula Newsletter – April 2017

Latest news from the OpenNebula project, highlights from the community and the dissemination efforts carried out in the project this past month in this monthly edition of your favourite cloud management platform’s newsletter.

June is around the corner! The OpenNebulaConf US will take place on June 19-20 in Cambridge, Massachusetts. You can already check the agenda with keynotes by Akamai, Telefonica and Harvard, and still benefit from the early bird registration until 12th of May.

The following OpenNebula TechDays are drawing a lot of attention. Madrid (hosted by Telefonica), Sofia (hosted by Storpool) and Barcelona (hosted by CSUC) registrations are almost full, check the agendas if you are interested in attending.

OpenNebula new major release is almost in feature freeze, and the numerous new additions are being stabilized. The vCenter driver is getting a major revamp in terms of storage and network management (check out more details in this article), non persistent disks and storage quotas, as well as network creation, mean an important boost in vCenter support. These new features will enhance OpenNebula provisioning model over vCenter based infrastructures, increasing the already wide range of use cases that can be implemented.

pasted-image-at-2017_04_28-03_00-pm

OpenNebula HA configuration in the front-end has been possible for quite a while. It currently relies on external components to ensure this HA, but the team decided that we may as well go all the way and implement HA natively in the OpenNebula front-end, implementing a consensus algorithm directly in the ‘oned’ core. The key improvement is the easier setup of the HA and the reduction of third party dependencies (no fencing, no corosync needed) and even more importantly, much less painful (in fact, completely ) failure recovery. Extensive testing is now performed on this functionality so you can add yet another 9 in your OpenNebula cloud availability!

More exciting features in 5.4 are: VM to VM and VM to Host affinity/antiaffinity using VM Groups, image persistency selection, modifiable semantics for permissions, IPv6 non SLAAC Address Ranges, Linked Clones support, improvements in monitoring drivers and much more!

Check out in the project’s development portal all the things we are still working on.

Building a ecosystems is instrumental in the success of a open source project. Thanks to people interested in OpenNebula, the amount of use cases that can be built with OpenNebula keeps growing and growing.

For instance, Devuan support is now a reality in OpenNebula, with support packages that ensures a proper contextualization of this novel and refreshing linux distribution.

It is always with pleasure hearing how people learn about OpenNebula, and realize that we’d been making cloud computing easier for you for quite a while now. Also, and as always, we love to see our friends at NodeWeavers being so supportive all over this last years. Kudos!

We would like to thank everyone that is actively supporting new OpenNebula users (or more seasoned users) in our support forum. Your actions are extremely useful for the adoption of OpenNebula around the globe!

An indicator of the health of the development community is the number of open pull requests in the OpenNebula GitHub page. We do our best to review and incorporate those aligned with the OpenNebula roadmap. Thanks!

OpenNebula Newsletter – March 2017

This monthly newsletter features the latest developments in the OpenNebula project, highlights from the community and the dissemination efforts carried out in the project this past month.

As you may know, the first ever US edition of the OpenNebulaConf will take place on June 19-20 in Cambridge, Massachusetts. Check out the keynotes by Akamai and Harvard, and reserve your seat in Boston! The complete agenda will be out in a few days.

Technology

OpenNebula 5.4 is going to place a new mark in cloud management excellence. A wealth of new features are being now stabilized, and that is what’s keeping the development team busy these days. As you know, the vCenter driver is getting a major revamp in terms of storage and network management (check out more details in this article). These new features will enhance OpenNebula provisioning model over vCenter based infrastructures, increasing the already wide range of use cases that can be implemented with your favourite Cloud Management Platform.

Let us lay down another set of features that are recent arrivals to the release:

  • Enhanced VM history logging
  • Image persistency selection
  • Modifiable semantics for permissions
  • IPv6 non SLAAC Address Ranges

.. and there will be more before the beta is released by the end of the month!

The team is particularly excited about the scheduler new ability of creating VM Groups with roles in which you can define affinity/anti affinity between VMs and virtualization hosts. This way OpenNebula supports use cases where VMs needs to be placed together for license issues, network performance reasons (place the DB and server together for instance), computational reasons or a wide range of other use cases. As usual, a picture speaks a thousand words. This feature has been sponsored by BlackBerry in the context of the Fund a Feature program.

Community

New advancements in the community are always a pleasure to review, it is the time to notice that the OpenNebula community is as supporting and caring as always. Newcomers surely feel the warmth of the support forum, where users, developers and integrators give their best to aid users with questions and problems about OpenNebula and really interesting use cases. We’d like to show this spirit with this thread, where people show their best to help use OpenNebula with resources from a hosting company. Way to go!

It is always a pleasure learning how OpenNebula is used in a wide range of industry niches and institutions, like it use in the Turin INFN science cloud. Building reliable and useful, real world clouds is our main goal all along!.

An excellent post describing the hybrid model and why is interesting for enterprises and institutions is featured in the OpenNebula blog this month. The hybrid model in OpenNebula is a native capability, which can leverage the traditional cloud promise: infrastructure elasticity.

The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer.

NodeWeavers shows us how to create an OpenNebula cloud in record time. Whoa! Their portable cloud looks nifty indeed!

We are very proud to announce that OpenNebula is a key components of the recently announced Telefonica rendering of the CORD framework (R-Cord)! We believe this is an important step to develop resilient clouds to deliver residentials phone and cloud services to end users. The architecture of the solution can be found here and it is a good read for all people interested in cloud and NFVs.

The OpenNebulaConf is the perfect spot to meet up with other cloud professionals and take the temperature of the cloud computing field (check the material of 2016 edition if you want to know more). The first US edition of the OpenNebulaConf is happening this 2017, as one of two OpenNebulaConf editions this year, one in US and the other in Europe. The US edition will take place on June 19-20 in Cambridge, Massachusetts, and the European edition will be held in Madrid, Spain, on October 23-24.

June is approaching fast! Have your seat prepared in Boston? If you are interested listening at what Harvard and Akamai have to say about their use of OpenNebula in their production infrastructures, then you need to move quickly and make sure that you get a place!

This past month members of the OpenNebula team went to Prague, and did the first test on the field of the new tutorial format where the cloud is deployed within a public cloud provider. This helped a lot for people with Windows or 32 bit laptops.

OpenNebula Newsletter – February 2017

Be up to date with this monthly newsletter of the OpenNebula project with the latest advances in in the technology, community work and the dissemination efforts carried out in the project this past month.

As you may know, the first ever US edition of the OpenNebulaConf will take place on June 19-20 in Cambridge, Massachusetts. The final keynote lineup will be announced shortly. The call for presentations is open through March 17 and the very early bird registration is available through March 20.

Our first release of the software was 9 years ago. Find our vision of these past years in this post.

Technology

OpenNebula 5.4 is approaching fast its first beta release. The vCenter driver is undergoing a major refactoring, and the storage and networking aspects, as well as import mechanism are getting a whole pack of new functionality. Other important functionality that will make it into 5.4 is: linked clones, vSphere 6.5 support, public and private marketplaces, new cache mechanism that means performance enhancements, and much more!

But not only vCenter is getting its share. More general functionality is also in the works, with exciting new possibilities like defining VM Groups to implement affinity and anti affinity rules for VM deployment. This enables multiple use cases in which the colocation (or not) of VMs between them or with particular hosts is relevant. This added to the improvement in permissions definition -giving more flexibility to who can execute what-, enhanced history logging, image persistency selection, general Sunstone improvements and many more means that 5.4 is going to be special release indeed, which we believe will bring much joy to cloud admins and users alike.

Saying that the OpenNebula community excels is an understatement. The ecosystem keeps getting richer thanks to amazing contributions such as this one. LXDoNe is an active project based on an add-on that allows OpenNebula to manage LXD containers. It contains a virtualization and monitoring drivers, and it feature life cycle control: deploy, shutdown, restart, reset, suspend and resume containers.

It is a fact that the OpenNebula technology has a broad adoption, not only in US and Europe, but all around the globe. This is an important step towards standardising OpenNebula as the de facto Cloud Management Platform for IaaS infrastructures that strive for simplicity and innovative features. This is why it is of the utmost importance the huge work made by people all around the world to spread the OpenNebula word to different countries. We want to share with you some of the recent efforts in different languages:

OpenNebula Newsletter – January 2017

The OpenNebula newsletter brings the latest news, advances in the technology, community work and the dissemination efforts carried out by the OpenNebula project this month.

We bring some big news this month! There will be two OpenNebulaConf editions this year, one in US and the other in Europe. The US edition will take place on June 19-20 in Cambridge, Massachusetts, and the european edition will be held in Madrid, Spain, on October 23-24.

Looking for a job in cloud computing? We are still looking for Cloud Developers and a Community Specialist to join our team, check this for more details.

Technology

A new maintenance release of OpenNebula 5.2 was released, OpenNebula 5.2.1. This release brings minor improvements in the SDRS clustered vcenter datastores, vlan management and the ec2 driver set. Also, a significant number of bugs have been fixed in 5.2.1.

The team is grooming OpenNebula 5.4. A lot of new features are being worked upon, with a focus on the vCenter integration. Besides all the improvements described in our December newsletter, we’ve decided to introduce a very demanded feature in the vCenter drivers, the ability to create linked clones from OpenNebula. A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation. This requires a special VM Template with snapshots included, the import process will allow to change the VM Template to meet this requirement or alternatively clone it and change it so it does. Nice and simple! You can check the full planned change log in the development portal.

New contextualization packages were released as well. new versions of the OpenNebula contextualization packages for Linux (ver. 5.0.3) and Windows (ver. 5.2.0). For Linux, this is mainly a bugfix release with 2 significant improvements. For Windows, this is a very first release, newly distributed as the MSI package.

And last, but by no means least, vOneCloud 2.2 is already out! This release brings the improvements of the latest Excession release to the appliance. vOneCloud is zero intrusive (although it fully manages the life cycle of VMs), try it out without the need to commit to it. If you don’t like it (as strange at that may be!) you can just remove the appliance.

Community

This last month we announced officially the OpenNebula Champion Program. Champions are passionate volunteers who work to connect, teach and spread OpenNebula. They represent OpenNebula and help to teach and spread OpenNebula, throughout the world.

vOneCloud is solving a big problem in the self provision of VMware resources. An excellent article in The Register beautifully lays out the simplicity it introduces in a sometimes overbloated paradigm. Being named as one of the five open source tools admins need to know is an honor.

It is a real luxury to count with excellent members (and Champions!) in our community. This extra testing makes OpenNebula more robust and more production ready, and we deeply appreciate that. We also get to receive outstanding contributions like this one, enhancing the virtual router with Load Balancing features. Amazing, big thanks from the team!

And keeping the ecosystem up to date is not small task either, so this update of the Nagios Probes for Monitoring OpenNebula and OCCI is good news.

OpenNebula 2016: Year in Review

christmas_one_2016We are approaching the end of this year 2016, winter has finally come, and we wish to thank all those individuals and companies that helped with the numerous achievements of OpenNebula throughout the year.

OpenNebula is keeping its momentum, widening its adoption and turning into a very mature product, with more than  9 years of development behind. We like to give a special recognition to the over 1.000 contributors registered in the development portal, who help advance OpenNebula by submitting bug fixes, patches, feature requests, …. We look forward to your contributions to code development!.

Also, we would like to thank Blackberry,  Unity and the Université Catholique de Louvain for funding general interest features that are made available publicly in OpenNebula releases through the Fund a Feature program. The community is certainly in debt with you.

It is always difficult for an open-source project to know who uses its software. So we consider ourselves lucky to know that there are more than 3.500 production OpenNebula clouds connected to our marketplace, with the largest one spanning over 16 data centers with over 300.000 cores. This year a milestone was achieved with more than 180.000 downloads of the OpenNebula packages.

Two major OpenNebula releases were published this year: 5.0 Wizard and 5.2 Excession. Moreover, three maintenance versions were released to fix bugs and polish features. Focus in future release will be centered in the vCenter integration, without neglecting the default hypervisor for OpenNebula clouds, KVM. The plan is to bring vCenter up to speed with the KVM support.

vOneCloud achieved v2.0 this year, an important milestone that allowed to settle a number of features and plan for the future roadmap. Lots of new vCenter related features are present in OpenNebula and will make their way to vOneCloud, specially with the redesign expected in OpenNebula 5.4 of the vCenter integration, that will bring full storage and network manage to the table. vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers and a slick self-service portal.

The community has been very active engaged this year 2016. Many contributions in the form of new addons, functionality patches, feedback for future releases, messages in the forum, twitter and so on were delivered in the past 12 months.  You can check these contributions, along with other details about the great progress that we have seen for the OpenNebula project in our monthly newsletters. We are also announcing our new Community Champions Program. An exclusive group of passionate technology and community leaders that help sustain and grow our user base. They represent OpenNebula and work to connect, teach and spread OpenNebula, throughout the world.

This year’s OpenNebulaConf was held again in in Barcelona and featured very interesting keynotes by relevant users like Telefonica or Akamai, among others. It featured three days packed with interesting talks and great experiences exchange. It was a great success thanks to the support and participation of all of our community members, speakers, sponsors and friends. You can check our YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference.  For 2017 we are planning to break down the conference in two instances, one to be held in Europe and another in the US. Yes, our first conference in the US. Stay tuned!

Also this year, members of the OpenNebula team participated in several OpenNebula TechDays around the world. These are full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop and presentations from community. We want to give a warm thank you to all organizations that hosted a TechDay in 2016 for their hospitality: Mimos in Kuala Lumpur, StorPool in Sofia, Rentalia in Madrid, ContainerizeThis in Dallas, C151 Data Centers in Toronto, Harvard FAS Research Computing in Cambridge, BIT.nl in Ede, Netways in Nüremberg and Trinity College Dublin in Dublin. 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.

Finally, we want to highlight the participation in both VMworld Europe and US, where the team were showcasing vOneCloud functionality over vCenter.

Community

We are very happy with the feedback given by the community. OpenNebulaConf 2016 was the perfect place to reunite with all the OpenNebula folks, and to share with them our plans for your favourite Cloud Management Platform.

For instance, we love tweets like this, it helps reminding us why we iterate OpenNebula to give users the smoothest experience.

So far we are happy with @opennebula – much more developer/admin friendly

It is also a joy to learn who is using OpenNebula to build production clouds, and how they are using them. This is a very nice example of a very useful use for an OpenNebula cloud. Having an OpenNebula cloud deployment in the European Space Agency (and, more importantly, knowing about it) is a good kick!.

We also want to give the thumbs up to those kind souls that give us a hand helping newcomers to set up their OpenNebula clouds. It is important to give a warm welcome to people willing to understand OpenNebula and approaching through the user forum, so thanks!

Outreach

If you are new to OpenNebula, one of the best ways of catching up is attending the OpenNebulaConf. You have the chance to meet OpenNebula users with real use cases and production environments, and to solve the doubts you may have about the technology to build private and hybrid clouds. If you are wondering what the OpenNebulaConf looks like, check the post with the material of 2016 OpenNebulaConf. Check out the YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference. Stay tuned for next years location and format, there will be surprises!

Besides the conference, the OpenNebula team also organize more local, one day events called the OpenNebula Cloud TechDays. These events are designed to learn about OpenNebula with a hands-on workshop on cloud installation and operation, and presentations from community members and users. We’ve opened the Call for Hosts for the TechDays in 2017, so if you are willing to host one for the local OpenNebula community, and give us a shout.

The OpenNebula team is growing at a fast pace. Are you looking to get into the cloud professionally? If you are looking to work in an agile environment to develop new features and integrations and participate in the upstream community, this is your chance. Check out the OpenNebula Systems vacancies if this is the case, we are currently interested in Cloud Developers and Community Specialists.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.

OpenNebula Newsletter – November 2016

Learn what kept the OpenNebula team busy this last month of November, the project activity, latest news, advances in the technology, community work and the dissemination efforts carried out.

You can check the material of the OpenNebulaConf 2016 on this blog post, including pics, slides and videos of the keynotes
We are looking for Cloud Developers and a Community Specialist to join our team, check this for more details.

Technology

Team is working hard on the next release, 5.4. An emphasis is given in vCenter integration, but also great advances are being worked upon on other areas:

  • Live disk resize operation, not only at boot time but while the VM is in running state
  • Full network management in vCenter, including the ability to create Networks and distributed vSwitches
  • Full storage management in vCenter, including resize and non-persistent images. This will effectively move the vCenter integration
  • Allow Folder definition for VMs in vCenter
  • Virtual Machine save for vCenter
  • Native HA for the OpenNebula controller
  • Affinity/Anti Affinity schedule options for VMs
  • Fine grain ADMIN and MANAGE VM operation assigment
  • More detailed history information, including user information
  • Many Sunstone goodies!

…and many more features related with Sunstone, Database, upgrade path and more OpenNebula subsystems. We are working to make OpenNebula 5.4 the most useful and robust OpenNebula release to date!

Also, an update of the VMware Cloud Reference Architecture was published. The update includes latest features in OpenNebula releases, like:

    • OpenNebula now allows to upload, clone and delete VMDK files.
    • VM importing workflow has been greatly improved through Sunstone, making it easier to import your existing workload into OpenNebula.
    • Resource pools defined in vCenter are supported by OpenNebula so available memory and CPU can be partitioned. When launching a VM from OpenNebula, a resource pool can be selected automatically or the user can choose one.
    • When a VM is instantiated from a VM Template, the datastore associated can be chosen. If DRS is enabled, then vCenter will pick the optimal Datastore to deploy the VM.

and much more!

Community

After the Conference hangover (both literally and figuratively), the community has been as active as ever.

We are restructuring the OpenNebula add-ons to keep track of those add-ons that are not longer maintained and we discourage the use of. If you are an add-on maintainer, give us a shot in the forum so we know about it.

As we always emphasize, it is very encouraging and important for an open source project to receive messages publicly like this.

Excellent summaries about OpenNebula, like the one that we recommend reading in this blog post, are a great way to spread the OpenNebula word. Kudos!

OpenNebula is a free and open source software solution for building clouds and for data centre virtualisation. It is based on open technologies and is distributed under the Apache License 2. OpenNebula has features for scalability, integration, security and accounting. It offers cloud users and administrators a choice of interfaces.

Another, and even more important, effort by our users can be seen in this blog post by Fuze, detailing their production use of OpenNebula and how it powers the infrastructure that boost their business. We are immensely proud and grateful for this information guys!

cloud_orchestration_v2

Currently, Fuze Private Cloud has a central OpenNebula deployment in a data center in the eastern part of the US. This fault tolerant OpenNebula deployment is configured to connect and manage Fuze data centers across US East/ West, Australia, Asia, and Europe.

By the way, we are taking care of the infrastructure that runs our web page, development portal, marketplace … we appreciate your patience. If you notice anything strange, let us know.

The team focus has now shifted to the next release, 5.4. Great functionality is planned, with an emphasis in vCenter integration. Expect great advances in this regard. Yes…we mean network management!. Also, full storage handling (non persistent images FTW!).

Community

Well, the community has been busy this month preparing their plane tickets and visit to Barcelona. It has been a blast at the Conf, and lots of interesting talks has shown us that OpenNebula is being used in amazing and crazy infrastructures around the world. We had the chance to host in our blog this quality post. This is an amazing work (thanks Marco!), which introduces Rancher and show how to launch OpenNebula Virtual Machines from the Rancher UI and provision them to run Docker compute hosts, which can then be used to run Docker containers. The post also comes with a promise!

That’s all, we will be back soon with another post about the integration of Rancher and OneFlow to deploy multi-tier services on OpenNebula clouds. Stay tuned!

opennebulamachinedriver
It is so good to know that old OpenNebula friends are also engaged in the community (like old but not forgotten OpenNebula contributors that showed up at the Conf)! For instance, Skymix is tinkering hard with OpenNebula with other technologies.

Very good news have arrived this last month from the community in the field of OpenNebula’s hybrid capabilities, extending the number of public clouds supported by OpenNebula to build hybrid cloud deployments. A new set of drivers developed by CSUC are now available as an add-on, enabling the hybrid extension of your OpenNebula cloud to any public cloud provider implementing the vCloud API. Check this exhaustive post for details. The software can be found in github

“With this addon, real hybrid architectures can use OpenNebula’s rich set of infrastructure management tools to manage cloud deployments across VCLOUD private, public and hosted cloud platforms.”

Outreach

It has been a pleasure! The OpenNebulaConf 2016 has been a real success, with awesome keynotes including usage of OpenNebula in Akamai and Telefonica, high quality tutorials and excellent workshops. We want to thank all the attendees, and especially the sponsors, for providing such a great atmosphere for the exchange of experiences, help to the newcomers and in general for being such a great community. It has been great to see you all, the team is looking forward to seeing you again next year!

The Conf had an educational twist that has definitely pleased the attendees. The workshops were very well received, and we believe this is the direction that we want to give the Conf, as it gives an extra value for the attendees, which not only see real world examples of OpenNebula usage but learns how to use the software, and how to tweak it. The first day tutorials were also well received, make sure that you attend next year to either the basic or the advanced one, they are a real bonus of the conference.
