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.

We Have Redesigned the Public MarketPlace!

The new MarketPlace is in the same place, and looks almost the same, but it’s now easier to use than ever!

marketplace

You can still see your favourite appliances from within Sunstone:

marketapps

But the good news is that the way you can contribute to the MarketPlace has changed drastically, it’s now a much simpler procedure, far more comfortable for developers. To add a new MarketPlaceApp you simply need to send us a pull request to this repo:
https://github.com/OpenNebula/marketplace

The procedure is quite intuitive and is explained in detail in the README.md of that repo, but in a nutshell you need to:

  • Fork the repo
  • Create a new folder for your company
  • Generate a uuid using uuidgen for instance
  • Create a new appliance file following the syntax explained in the README.md file. Feel free to take a look at other examples in the repo.

So if you want to contribute a new appliance, you can start by following this guide to enable OpenNebula compatibility, and then you can submit it the new MarketPlace!

Happy contributing!

9 Years of OpenNebula!

nine

Today is the 9th anniversary of the founding of the OpenNebula open source project. We still remember the early days of OpenNebula, when we decided to start an open-source project to grow, distribute and support the software prototypes that we developed to support our research in virtualization management on distributed infrastructures. Yet here we are, nine years later, with one of the most successful projects in the open cloud ecosystem.

OpenNebula has grown into a widely-used user-driven project, with lots of examples of production use in academia, research and industry, over 100K downloads from the project repositories in the last year, more than 1,500 clouds connected to our marketplace, and large-scale infrastructures with tens of data centers and hundreds of thousands of cores. We are very proud of this growth as the only fully-open enterprise-ready management platform to build clouds.

None of it would be possible without your help, the hard work of thousands of users and contributors!

…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!

uploadimage3

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.

Outreach

The OpenNebulaConf 2016 has been a real success with awesome keynotes including usage of OpenNebula in Akamai and Telefonica. Also, it featured high quality tutorials and excellent workshops, which were very well received, as were the first day tutorials. Make sure that you attend next year to either the basic or the advanced one, they are a real bonus of the conference!

To sweeten your way to next year’s Conference, and to recap the contents of the different keynotes and lightning talks, we published a 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. Enjoy.

We will also be defining shortly the TechDays for 2017. Stay tuned if you are interested to host an OpenNebula event!

Update of VMware Cloud Reference Architecture

A year ago OpenNebula Systems published the VMware Cloud Reference Architecture, a blueprint to guide IT architects, consultants, administrators and field practitioners in the design and deployment of public and private clouds based on OpenNebula on top of VMware vCenter. This reference architecture is intended for organizations with existing VMware environments or expertise who want to limit changes to their underlying VMware infrastructure, but see benefits in a common provisioning layer via OpenNebula to control compute workloads and want to take a step toward liberating their stack from vendor lock-in.

Many things have changed since that document was published. This is a brief summary of what’s new and ready for you:

  • 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.
  • New disks can be hot-plugged and OpenNebula can be informed from erasing the VM disks if a shutdown or cancel operation is applied to a VM, so users won’t lose data accidentally.
  • Support for vCenter customization specifications, as a complementary alternative to contextualization.
  • Multi vCenter cluster can be now defined in a single VM Template definition.
  • Control how disks are managed in vCenter, through the KEEPS_DISKS_ON_DONE template variable which will help you to protect users data against accidental deletions.
  • Datastores in a Storage DRS can be used as individual datastores by OpenNebula.
  • A bandwidth limit per VM network interface can be applied. VM’s network usage information is now gathered from vCenter.
  • It’s possible to access the OneGate server from vCenter VMs since the onegate token is passed through to the VM.
  • And last but not least, cool features added to Sunstone: a smoother vCenter’s resource import, the Cloud View functionality has been extended, new tags for resources.

This blueprint has been created from the collective information and experiences from hundreds of users and cloud client engagements so your feedback is extremely valuable.

More features are continuously being added, OpenNebula is a project in constant evolution, so stay tuned and do not forget to send us your feedback!

How We Use OpenNebula at Fuze

fuze_logo
Fuze, headquartered in Cambridge, MA with additional locations in North America, Europe, Asia and Australia, is a global, cloud-based unified communications platform that empowers productivity and delivers insights across the enterprise through a single unified voice, video, and messaging application. Fuze allows the modern, mobile workforce to seamlessly communicate anytime, anywhere, across any device. With Fuze, customers have a single global carrier network leveraging a resilient private cloud infrastructure and QoS-engineered network to deliver the best enterprise-class IP PBX voice service available.

Given the company’s record momentum and growth, scaling the private cloud infrastructure to meet the global expansions and growth is a key to its customers’ satisfaction. In mid-2015, we deployed OpenNebula as part of the Fuze Private Cloud Management Stack to achieve a continuously reliable growing private cloud spanning Fuze global infrastructure.

Here’s a quick look at the key features of OpenNebula that powered Fuze Private Cloud:

  • Simple and lightweight deployment and easily extendable being open source.
  • Self-Serve capability through GUI (Sunstone), CLI and API.
  • Multi-tenancy built-in providing segregation among internal workloads.
  • Supporting Agile DevOps by abstracting underlying infrastructure and supporting mainstream hypervisors besides public cloud bursting.
  • Automated VM Orchestration via contextualization that personalize instances on instantiation time.
  • Service Orchestration provided by OneFlow and OneGate that support multi-tier applications using role based instances. Besides, OneFlow has the ability to apply auto-scaling and recovery rule support based on either generic or custom application attributes pushed via OneGate.

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.

cloud_orchestration_v2

VMware ESXi/vCenter 6.0 is the dominant virtualization technology used across its data centers backed by SAN-based storage and we also use Amazon Web Services. OpenNebula leverages the SOAP API offered by each DC vCenter to manage the entire global cloud infrastructure and present it to the different engineering teams as an effective single orchestration pane of glass. In addition, we connected OpenNebula to a few AWS Virtual Private Cloud (VPCs) with dedicated tenancy that it bursts into where applicable.

We are currently running OpenNebula 5.0 which brought in enhanced user experience through Sunstone and renamed lifecycle states along a redesigned Marketplace. We will upgrade to OpenNebula 5.2 soon to make use of the upgraded hybrid cloud drivers.

Overall, the OpenNebula project has taken Fuze Global Private Cloud to the next level and continues to be a fundamental factor for continuous innovation and customer satisfaction.

OpenNebula Newsletter – October 2016

labels_searches_sunstone
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.

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.

OpenNebula 5.2 ‘Excession’ is Out!

The OpenNebula project is proud to announce the availability of the stable release of OpenNebula 5.2 ‘Excession’. OpenNebula 5.2 (Excession) is the second release of the OpenNebula 5 series. A significant effort has been applied in this release to stabilize features introduced in 5.0 Wizard, 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. Also, new components have been added to enhance the OpenNebula experience.hyperlinks_sunstoneOne important new module is the IPAM subsystem. In order to foster SDN integration, an important step is being able to integrate OpenNebula with existing IPAM modules, in those cases where outsourcing of IP management is required in the datacenter. Fitting in the OpenNebula architecture design principles, the IPAM subsystem interacts with IPAM servers using drivers, and as such a IPAM driver lets you delegate IP lease management to an external component. This way you can coordinate IP use with other virtual or bare metal servers in your datacenter. No default integration is provided, but rather to effectively use an external IPAM you need to develop four action scripts that hook on different points of the IP network/lease life-cycle.

Another great addition in Excession is the ability to use group bound tokens. The goal is to be able to use OpenNebula for different projects, which are identified with different groups. For instance, the same user can use OpenNebula for “WebDevelopment” project and a “BioResearch” one, for instance. This user can request a couple of tokens tied to each of these groups. Upon login with the “WebDevelopment” token, she will only be seeing resources from that particular project, and all new resources (VMs, images, networks) will be created within that group, isolating them from the “BioResearch” group. This feature is available both in the CLI and Sunstone, with helpers and dialogs to create, maintain and use the tokens.

All the OpenNebula drivers have been improved for robustness. For instance, a new default timeout (which is configurable) has been defined to identify hanging operations and kill crashed processes. In this regard, the EC2 drivers has also been thoroughly revisited, being updated to the v2 of the aws ruby gem, ensuring compatibility with all Amazon EC2 regions. Error handling has been improved as well in the EC2 driver, adding operation retries to circumvent those situations where the EC2 API is not consistent, and adding improved logging.

Sunstone is the face of OpenNebula for both administrators and users, and hence a constant target of enhancements to improve usability. Excession brings to the cloud table stabilized features that were introduced in the Wizard maintenance releases, like for instances advanced searches (that now are maintained regardless of tab switching), labels colors and ergonomics, improved vCenter dialogs and import tables (now with feature à la Gmail), hyperlinks to access resources displayed in the info tabs, and many other minor improvements.

There are many other improvements in 5.2:

  • revamped group mapping in LDAP authentication -now being dynamic mapping-
  • limiting bandwidth per VM network interface in both KVM and vCenter
  • rollback mechanism in failed migrate operations, significantly improved fault tolerant hook -to provide high availability at the VM level-,
  • improved SPICE support, improvements in ebtables and Open vSwitch drivers, multiple CLI improvements -i
  • … and much more.

As with previous releases, it is paramount to the project to help build and maintain robust private, hybrid and public clouds with OpenNebula, fixing reported bugs and improving general usability.

This OpenNebula release is named after the Ian M. Banks novel, a recommended read, as well as having a fitting slang meaning, “something so technologically superior that it appears as magic to the viewer.”. We are confident that OpenNebula, if not really appearing as magic, at least solves elegantly your IaaS needs.

OpenNebula 5.2 Excession is considered to be a stable release and as such, and update is available in production environments.

The OpenNebula project would like to thank the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.

The group token functionality and dynamic LDAP group mapping into OpenNebula groups were funded by BlackBerry in the context of the Fund a Feature Program.
