A summary of the activity of the OpenNebula project this last month.

The OpenNebulaConf EU 2017 is around the corner! This month in Madrid, keynote speakers such as BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community, as well as other prominent members of the OpenNebula community will be sharing their experiences with OpenNebula. There are limited seats, register ASAP!

Technology

A new maintenance release of OpenNebula, 5.4.1, has been released this month. This release introduces new functionality:

Also, multiple bugfixes related with vCenter and Sunstone, as well as in other subsystems has been fixed. Take a look at the release notes for an exhaustive list of changes introduced in this version.

Based on OpenNebula 5.4.1, the latest version of vOneCloud (3.0.2) has also been released, bringing all the new functionality to the best cloud manager on top of vCenter.

This month the team is set to prepare the roadmap for the next OpenNebula version, 5.6. It is the perfect time to let us know about the features you’d like to see in OpenNebula!.

Community

Having our community spread the word about OpenNebula is the best thing that can happen to an open source project. It was somewhat of a surprise to learn that in the AWS summit in Madrid,folks from Securitas Direct showcased their development cloud built on OpenNebula and Ansible. Pretty cool stuff!

#SecuritasDirect presenting their hybrid cloud environment based on @Ansible @OpenNebula @VMware @AWScloud and @Oracle VM #AWSSummit

Also, having long time partners like NodeWeavers winning relevant prizes fills us with pride and joy! Kudos from here and thanks a lot for believing in us!

With OpenNebula Medusa 5.4 published this past July, the team is focusing now on the next maintenance release, 5.4.1, as well as preparing the roadmap for the next major release, OpenNebula 5.6. This is the perfect time to contribute your ideas to improve OpenNebula, this page from the project’s website lays out all the needed info (TL;DR create a request in the development portal).

If you were wondering how to add patches to them or build non stable versions this is your lucky month, since the team just published the package build repository, so everyone can build their own OpenNebula packages.

This month of August was also good news for vOneCloud users, with the release of vOneCloud 3.0.0 (and subsequent 3.0.1), which brings all the innovation introduced in OpenNebula 5.4. You can check the details in the release notes, the following are highlights of the new functionality in vOneCloud 3.0.0:

  • Enhanced storage management, vOneCloud is fully aware of all VMs disks. Non-persistent images and volatiles disks are now supported.
  • Storage quotas and datastore capacity check, never run out of capacity correctly dimensioning the available datastores and the storage quotas given to end users
  • Linked clone support, add support for linked clones for VMs at the time of importing a VM Template
  • Disk resize capabilities, resize the capacity of a VM disk at boot time or when the VM is in poweroff
  • Network creation support, a new vCenter network model is available in virtual network definition, standard and different port groups and vSwitches can be created from within OpenNebula. VLAN IDs, MTUs and number of ports can be specified when a port group is created.
  • Full storage and networking support in imported VM Templates, images and networks representing disks and network interfaces are created for VM templates and folder placement features.

Community

The team put a lot of effort in Medusa, and we want to thank you for the marvellous feedback received in the community forum, as well as the support given by the community to newcomers and people willing to upgrade their OpenNebula infrastructures.

It is also very welcome how people are keeping up to date with the latest releases. We hope you enjoying using OpenNebula as much as we enjoy developing it!

Integrations such as this one from UDS Enterprise gives indeed more flexibility to OpenNebula, with the ability to manage a VDI environment in an OpenNebula based infrastructure.

Release 5.2-4.1 of the LXDoNe OpenNebula addon has been released. LXDoNe add LXD management capabilities to OpenNebula, bringing container management to the cloud!

OpenNebula Newsletter – July 2017

Check out the highlights of the OpenNebula project this last month regarding technology, community and outreach in this monthly newsletter of your favourite cloud management platform.

The agenda for the OpenNebulaConf EU 2017, in Madrid this October have been announced, including BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community. Also, you can check the videos, pictures and slides of the OpenNebulaConf US 2017 in this post.

Technology

OpenNebula Medusa 5.4 is out in the wild, and the team is now analyzing carefully the feedback given by users to identify any issue with the release. So far things are looking good, the team will probably be releasing a 5.4.1 maintenance release in September to address the minor issues seen in the forum.

In Medusa, 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. Three major features that are important to highlight follow.

An important focus has been on the vCenter integration, with an enhanced network and storage management. Also, new components have been added to improve the OpenNebula experience.

  • Full storage management. Non-Persistent images are now supported as well as volatile disks. OpenNebula is now aware of all VM disks and storage quotas can be enforced. Support for linked clones and Marketplace.
  • Full network management. It is now possible to create vCenter standard and distributed port groups and even vSwitches directly from within OpenNebula. You can assign a VLAN ID to a port group created by OpenNebula.
  • Improved monitoring. Up to two orders of magnitude of speedup.
  • An enhanced import process where naming limitations in imported resources has been removed and the ability to enable VNC automatically for Wild VMs.
  • Disk resizing, VM and Templates folder selection when a VM is deployed… and many more changes!

vcenter_vmdk_upload_sunstone_1
A new resource, the VM Groups, has been added to implement VM-VM and VM-Host affinity/anti-affinity rules. A VM group is a set of related virtual machines that may impose placement constraints based on affinity and anti-affinity rules. A VM group is defined as a set of Roles. A Role defines a VM type or class, and expressions to the VM Group can be added to define affinity between VM roles, or between VM and hosts. This ensures a dynamic approach to affinity/anti-affinity since new VMs can be enrolled to a particular Role at boot time, after the VM Group has been defined and other VMs added to it.

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 distributed consensus protocol provides fault-tolerance and state consistency across OpenNebula services.

And many other new features that can be checked out in the Medusa release notes.

The team is working now on a new release of vOneCloud, 3.0, which is going to bring all the excellence in vCenter management exposed by OpenNebula 5.4.

Community

Even in summer, the OpenNebula community does not go into vacation mode. It seems that it never sleeps

Spreading the word is a great support for the project, and it is very good news to learn how OpenNebula enables learning computer science and makes teachers jobs easier.

Software integrations with third party applications, like for instance this VDI (Disclaimer, tweet in spanish) really enriches the OpenNebula ecosystem.

Equally important are the maintenance of OpenNebula addons. Contributing an addon is great by all means, but maintaining it and extending the documentation, ie, keeping it alive, is what really makes it useful for future OpenNebula releases. This is why notices such as this new version of the LXDoNe or new documentation for the vCloud driver are very good news!

Outreach

The first ever OpenNebulaConf in the US was held this past June, in Boston to be precise. We had a lot of wonderful attendees and some really great speakers delivering really interesting talks and sharing their experiences. We would like to thank all attendees and speakers for their support.

OpenNebula 5.4 ‘MedusaBeta 1 and Beta 2 have been released this past June, and now the team is working at full throttle on stabilizing. Your feedback is of the utmost importance in this regard, so if you have the time please download and test the latest Beta, and let us know about your feedback in the community forum or the development portal.

Medusa is the third release of the OpenNebula 5 series. 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, support for linked clones, disk resizing, save as template functionality (this is a new addition working on Beta2) for vCenter VMs, disk save as functionality, automatic storage scheduling, storage quotas and many more! 5.4 Medusa takes a giant leap forward in vCenter support, bringing it up to speed with KVM VM management.

But there is more! 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 and many more!!

This OpenNebula release is named after the Medula Nebula, a large planetary nebula in the constellation of Gemini on the Canis Minor border. The OpenNebula team is now set to bug-fixing mode. Note that this is a beta release aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release.

This coming month of July is going to be very exciting as we believe it will set a new top mark on cloud management platform with the release of the stable 5.4 version of OpenNebula!

Community

So it seems that the OpenNebula community hasn’t yet gone into vacation mode. This month it features outstanding contributions which enrich greatly the OpenNebula ecosystem.
The first highlight we want to make is this nifty android vulnerability scanner using OpenNebula and android emulators. The scanner leverages OpenNebula VM management capabilities to provision VM emulators and then uses ADB to connect and start the analysis. Very good work!

Next, a new version of the integration component for OpenNebula and cloudkeeper has been released. Cloudkeeper read image lists provided by EGI AppDB, parse their content and decide what cloud appliances should be added, updated or removed from managed cloud. During the addition and update cloudkeeper is able to download an appliance’s image and convert it to the format supported by the managed cloud.

Learning how OpenNebula is being used in real case scenarios is very motivating. This is why the team is very excited with the OnLife Project by Telefonica, which aims to build a CORD implementation using OpenNebula to virtualize and advance the Central Offices which gives you guys internet connection. Cool, isn’t it?

Also cool to learn how people spread the world, like this very interesting talk on OpenNebula and Ceph given in the Harvard IT Summit by the FAS Research Computing group.

If you are an OpenNebula newbie and english does not flow strongly on you, but you know french, check out this tutorial on how to install OpenNebula over a Debian OS.

It is always pleasant to receive praise such as this one, specially after releasing a Beta version, and also specially being a Beta as feature packed as Medusa 5.4 Beta. We are counting on you to unearth as many nasty bugs as possible before the final release! Please let us know through the community forum or the development portal about such findings. The call for translations of the Sunstone web interface to different languages is still open, check out the instructions on how to contribute to the translations. THANKS!

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.

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 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.

Outreach

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.

Community

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:

Also, we want to salute our friends at NodeWeavers with their brand new 11 release. Also nice to note that OpenNebula is now featured in siftery!

Outreach

The first release of OpenNebula was 9 years ago!. We are very proud of the path we walked these past 9 years, and are very happy of all the use cases OpenNebula has powered so far.

Nine years ago, in February 2008, OpenNebula announced the first open-source management software for deploying private and hybrid clouds, and released one of the most transformative platforms for innovation in the cloud.

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.

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.
