2015 OpenNebula Cloud Architecture Survey Results

Executive Summary

This is the third survey of OpenNebula deployments since September 2012. The results of this voluntary survey were answered online between December 3, 2015 and December 11, 2015. While previous surveys were open for several months, responses in this survey were collected only over a period of one week because its goal is to have a snapshot on the architectural components of existing OpenNebula clouds in order to improve support for the most demanded infrastructure platforms and configurations.

Although several hundreds of organizations took part of the survey, we have only included in the analysis the 190 respondents that are using OpenNebula 4.x (latest series) and who we deem reliable because they have provided identification details that allow us to verify the answers of the survey. This is important given that our main aim is to have accurate and useful information about OpenNebula deployments. This Survey is not a market survey and does not express all OpenNebula deployments worldwide. Since the foundation of the open-source project in November 2007, OpenNebula has been downloaded more than 360,000 times from the project site (280,000 times since our first survey in September 2012 and 160,000 times since our latest survey in August 2014), not including other software repositories or third-party distributions.

Regarding the use of OpenNebula, the Survey shows 43% of overall deployments are in Industry and 13% in Research Centers. Most of organizations (80%) are in Europe, Russia or North America and use OpenNebula to build private clouds (93%). When asked about the type of workload, 73% said that they use OpenNebula for running production workloads.

Regarding the size of the clouds, 80% of deployments have fewer than 100 nodes and 10% of deployments have more 500 physical nodes. 51% of deployments consist of more than one OpenNebula zone and 5% run more than 10 zones. Among the advanced components offered by OpenNebula, High Availability at 73% is the most widely used, in correspondence with the predominant production usage of OpenNebula.

Regarding the building blocks of the cloud, KVM at 79% and VMware vCenter at 37% are the dominant virtualization platforms, and CentOS at 44% and Ubuntu at 40% are the most widely used linux distributions for OpenNebula clouds. The preferred choices for the storage back-ends are shared FS and Ceph at 60% and 40% respectively. Regarding networking, most of the deployments, 45%, use the Standard Linux Bridge for network configuration, 35% use 802.1Q, and 33% use Open vSwitch. 44% of deployments use the hybrid cloud functionality offered by OpenNebula. Amazon EC2 at 30% and Microsoft Azure at 16% are the most widely used public clouds.

In comparison to previous survey findings in 2014, there have been some changes:

  • OpenNebula shows its increasing maturity, with 73% of deployments in production compared to 62% reported in our previous survey.
  • Growth in North America has accelerated, now representing 30% of responses, up from 20%.
  • KVM provides the majority of OpenNebula support, growing from 48% to 79%.
  • There is a high rate of adoption in VMware environments from 28% to 37%.
  • Ubuntu grows from 36% to 40% and Debian falls from 33% to 22% as operating systems to build the cloud.
  • The use of the EC2 cloud API decreases from 25% to 10%.
  • The use of Ceph has grown considerably from 17% to 40%.
  • The use of LVM as storage solution decreases from 22% to 12%.

On the whole, OpenNebula continues to be loved by its users for its flexibility, 82%, simplicity, 80%, and openness, 72%. These results are aligned with our our mission — to become the simplest cloud enabling platform — and our purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure.

We would like to thank all respondents that took part in the survey!

They also include tutorials, lightning talks, and hacking sessions that provide an opportunity to discuss burning ideas, and meet face to face to discuss development.

The third OpenNebulaConf will open its Call for Sponsors and Call for Speakers in a few days, stay tuned for content updates.

And remember… OpenNebulaConfs are vendor-neutral events focused on real-world practices and how to successfully implement open source in your cloud.

We look forward to seeing you in Barcelona!

OpenNebula 2015: Year in Review

This has been a very interesting year in the Cloud Computing field in general, and in OpenNebula in particular. It looks like the field is consolidating, and we are past the Peak of Inflated Expectations slowly moving into the Plateau of Productivity. This can be inferred from the increasing number of enterprises that are implementing their in-house private clouds and offloading their computing needs to public cloud providers, showing that the paradigm did take off and it’s soaring towards computing efficiency.

In this regard, we are proud that OpenNebula celebrated this year its 8th anniversary, showing a degree of maturity fit for the most demanding production environments. The OpenNebula project is proud to deliver a truly open, vendor-free, user-driven software to build private and hybrid clouds, with design principles that focus on simplicity and flexibility. Our philosophy is not to break with the previous outstanding work in datacenters, but rather extending its functionality to take advantage of the cloud computing benefits. We think this is a unique vision in the field, and OpenNebula is the product of this believe.

With 2015 coming quickly to a close, we’d like to review what this year has meant for the OpenNebula project. You have all the details about the great progress that we have seen for the OpenNebula project in our monthly newsletters.

Solving Real User Needs in Innovative Ways

Two major releases were published this year: 4.12 Cotton Candy and 4.14 Great A’Tuin. Moreover, three maintenance versions were released to fix bugs and polish features. Several maintenance versions of AppMarket were also released.

4.12 Cotton Candy shipped with several improvements in different subsystems and components. For the first time, OpenNebula introduced the ability to generate cost reports that can be integrated with chargeback and billing platforms, and also presented to both the administrators and the end users. Each VM Template defined by the Cloud administrator can define a cost per cpu and per memory per hour. Extensively used features like SPICE, Security Groups and VXLAN were firstly seen in Cotton Candy

One of the main focus of 4.14 Great A’Tuin has been the Sunstone interface, which has been completely refactored for maintenance and performance reasons. However Great A’Tuin is probably the release of OpenNebula to date that features more new functionality. GPU support is a great addition to support HPC oriented infrastructures, importing existing running VMs into OpenNebula for all supported hypervisors (including the public ones), fully supported disk snapshots for Ceph and qcow2, image resizing, ability to ability to save VMs into VM Templates for later use, flexible context definition of network attributes, the list goes on and on. We feel this is the most mature and rich OpenNebula version, but we are not stopping here since work towards 5.0 has already started.

Moreover, four major releases of vOneCloud were released this year. Thanks to the amazing user feedback, the a virtual appliance for vSphere that transforms an existing vCenter deployment into an automated, self-service private cloud in a few minutes, is quickly growing its feature set to deliver a reliable, robust and mature product. vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers, self-service portal, or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. vOneCloud seamlessly integrates with running vCenter virtualized infrastructures, and can be set up if a few minutes and import the existing infrastructure resources, including running VMs.

We would like to thank the community members that have contributed with patches, documentation and feedback to the matureness of OpenNebula. Also, to the various organizations that have contributed to enhance OpenNebula through the Fund a Feature program: Blackberry, Echelon, Unity, BIT.nl, SURFsara and the Université Catholique de Louvain. We look forward to your contributions to code development!.

An Engaged Community of Users

The OpenNebula community is as healthy as ever, and fastly growing. The contributions to the software and its roadmap are vast, and cannot be briefly mentioned. We wanted to highlight a few integrations and feature extensions though, like one onesnooper, StorPool, Vagrant, LXC, nodejs binding, Saturnring, Kerberos, Chef, CloudVAMP, Docker, ZFS, and many many more. We are proud of our very much alive, proactive and engage community!

There are tens of thousands of deployments around the globe and OpenNebula is parked in some of the biggest organizations out there including Industry and Research leaders. OpenNebula roadmap is defined by its users needs. We just performed a survey to require input for the list of features that will be tackled for the next major update, OpenNebula 5.0.

2015 also marked the end of the distribution mailing list as the main mechanism of communication with our community, in favour of the new online forum, to keep this communication agile and fruitful.

We would like to thank all our users! It is out of scope to name all new users, but we want to give a wholeheartedly warm welcome to those new users that shared their experiences through our blog: Unity, Universidad Politécnica de Valencia, PTisp, Avalon, China Mobile, Rentalia and BIT.nl. If you are using OpenNebula, you are very welcome to contribute your integrations and experiences by writing a post in our blog or submitting your integration to the OpenNebula Add-on Catalog.

Spreading the Word

Spreading the OpenNebula word is of the uttermost importance for the project. The brightest highlight is, as usual, the OpenNebulaConf 2015. This year it was held in slick hotel Barcelo Sants in Barcelona and featured very interesting talks by relevant users: Runtastic, Unity, Citrix, RedHat, Fermilab, … Check out the videos, slides and pictures to get a glimpse of what you missed. A lot of new ideas for features and collaborations were fostered in this event, so expect a great and fruitful 2016.

In 2015 members of the OpenNebula team participated in several around the world. We want to highlight the VMworld Europe 2015 in Barcelona, Cloud Expo Europe in London and the Open Cloud Day in Bern. These events are great opportunities to evangelize people into what we think is the greatest Cloud Management Platform.

A number of high quality OpenNebula TechDays, full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop and presentations from community, were held this year. Check out the agendas of the Prague, Boston, Paris and Ontario TechDays.

We want to thank all organizations that hosted a TechDay in 2015 for their hospitality. We are organizing the schedule of TechDays for future months, send us an email or send it to the community discuss mailing list if you are interested in hosting a TechDay event. We also look forward to proposals to create a user group in your area. In a few days we will announce OpenNebulaConf 2016.

OpenNebula 2014: Year in Review

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

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

Why

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

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

Solving Real Needs in Innovative Ways

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

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

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

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

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

The New vOneCloud

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

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

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

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

A Vibrant Community of Users

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

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

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

Spreading the Word

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

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

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

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

***

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

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