OpenNebula Newsletter – June 2015

Check out what kept us busy this June. This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

We want to remind our users that OpenNebula Systems, the company behind the OpenNebula Project and vOneCloud, has established a new subsidiary to oversee all business operations and to support the OpenNebula community in the U.S. If you are interested in supporting the US OpenNebula community or contact us, let us know.

Technology

The OpenNebula team is not fooling around with the 4.14 release. We are settling on a code name for the release (do you like ‘Dark Horse’?), and meanwhile adding an impressive array of features. Probably the main highlight is the new snapshot management feature, that will let perform disk snapshots and maintain a history of them. The initial support would be only for Ceph (it is our storage backend of choice for medium to large deployments after all, read our reference architecture), and qcow2. OpenNebula will be aware of snapshot sizes, and allow to enforce quotas and also to report consumption via the accounting mechanisms. Pretty neat, is it not, hosting providers?

Another big highlight would be the inclusion of a new type of consumable, GPU. A VM would be able to consume GPUs, using PCI passthrough, to gain exclusive access to GPU PCI cards. Pretty neat, is it not, research institutions and supercomputing centers?

Sunstone is being reworking behind the scenes, and although final users will only notice minor changes in the GUI, rest assure that this is a very important feature for the future of Sunstone. Keep an eye on it!

Other features we are working on is image resizing (finally), system datastore flush for maintenance, import VMs capabilities for hybrid hosts, improved fault management with the inclusion of new VM state transitions (no VM left behind), improvements in the network context management, and many more. As mentioned before, we are not fooling around with Dark Horse, be sure to be ready for the beta version due at the end of July.

This month, a new set of contextualization packages was also released, with several nifty additionals like the ability to pass scripts directly to be executed at boot time, without having to create them first in the files datastore.

A new version of the drop in replacement for vCloud, vOneCloud, was also released. vOneCloud 1.6 comes with several improvements, like capacity resizing, resource pool confinement, improvements in VNC, and more. Make sure you update using the awesome one click updated.

Community

Keeping a healthy community is key for an open source project. The OpenNebula community is growing every day, contributing new pieces to an already rich ecosystem.
For instance, StorPool integration with OpenNebula is performed as a new datastore driver in OpenNebula. OpenNebula persistent and non-persistent images are stored in a StorPool cluster, and OpenNebula controls and monitors the StorPool cluster. An important contribution worth noted is on the works, promising to bring LCX support to OpenNebula.
User stories are also good addition to a project credibility. OpenNebula has been around for a while now, but we still are moved by our users from time to time when they decide it is time to announce to the world they use OpenNebula in their infrastructures. For instance, like Teledata did this month.

OpenNebula it turned out to be the most mature and proven Cloud-Stack available – lacking of unnecessary complexity or unneeded overhead.

And it is also nice to see how OpenNebula is being recognised as a solid alternative to commercial virtualization software. In this case, as an alternative to vCloud Director.
OpenNebula API is also being consumed by other components of the ecosystems to create amazing things like automated power management on opennebula based infrastructures, like the new release of CLUES.

Outreach

The upcoming third edition of the OpenNebulaConf will be held in Barcelona this October 2015.

vOneCloud 1.6 Released! Ease vSphere Provisioning

We want you to know that OpenNebula Systems has just announced the availability of vOneCloud version 1.6.

This new release of the appliance, tailored to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features.

  • In vOneCloud 1.6 is now possible to define virtual machine capacity, in terms of CPU and Memory presented to the guest OS, changing this value from the vCenter Template at the time of cloning a new Virtual Machine.
  • Along this line, it is also possible to resize the capacity of a Virtual Machine after deployment.
  • Moreover, it is also possible to confine vOneCloud users on a particular vCenter Resource Pool, making it possible to enforce company security policies by reducing the rights of the needed credentials by the appliance and also offering to vOneCloud users a subset of all the available hardware resources controlled by vCenter.
  • In order to facilitate the customization of Virtual Machines, in terms of configuring software packages and perform any generic administration task at guest OS boot time, vOneCloud introduces the ability to run any script at boot time, using a new set of contextualization packages.
  • Improvements are also offered in the VNC connection capabilities, to accommodate foreign keyboards.

The above features and components add to the already present ability to expose a multi-tenant cloud-like provisioning layer through the use of 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 virtualised infrastructures, leveraging advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family.

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 happen (as strange at that may be!) to don’t like it  you can just remove the appliance.

OpenNebula Newsletter – May 2015

Check out what kept us busy this May. This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

We are proud to announce that OpenNebula Systems, the company behind the OpenNebula Project and vOneCloud, has established a new subsidiary to oversee all business operations and to support the OpenNebula community in the U.S. This is excellent news for the OpenNebula Project! Read the details in the OpenNebula Systems press release.

Technology

Winter is over, Spring is here, and everything is blossoming. And yes, that includes OpenNebula features! The team is busily working on the upcoming 4.14 OpenNebula release, as usual following the roadmap driven by its users, via feature request or even the Fund a Feature program.
OpenNebula 4.14 will add an exciting new snapshot management feature, that will let perform disk snapshots and maintain a history of them. The initial support would be only for Ceph, as it is our storage backend of choice (have you read our reference architecture? now is the chance!)

Sunstone is undergoing a major refactor, since its structure has been left untouched for far too many releases. We are proud to say that now all the components of OpenNebula have clean code and best programming practices! Of course everything has room for improvement, and we did our best in this release for your favourite cloud web interface. Adding new features and polishing the interface is going to be easier than ever now, so expect a big boost in Sunstone for future releases.

A long awaited featured, widely demanded by users, was related to datastore maintenance. Migrating running VMs from one system datastore to another, in order to take offline one datastore or simply to free some space from it will be possible in the upcoming 4.14 release. Rejoice cloud admins!

Image resizing has also been in our backlog for too long, and finally we found the needed resources to develop it. We think this is a very important feature for OpenNebula users and admins, try it out and let us know if this is what you were looking for.

4.14 will have a plethora of new features and improvements, like an improved fault management with the inclusion of new VM state transitions (no VM left behind), improvements in the network context management (more flexibility at the time and place of defining network attributes, … . Make sure you try out the beta release, due in a few weeks.

Fun is always welcome in our community. The team choked in laughter after seeing this tweet from Carlo Daffara (kudos to your friends).

The Barcelona OpenNebula user group is very active, spreading the ONE word this month in the Suoders event, with interesting talks around the technology.

Serious matters are welcome as well. Our Terradue partners gave this talk at the EFIConf15 on Hybrid Cloud Strategy. Worth going through the slides.

What is the best way to move out of Amazon Web Services (AWS) or other public cloud services?

Well, according to iSpot.tv the answer is OpenNebula. Learn the reasons and the approach taken by them in this article.

The community is always contributing back. This month, it provided for instance gems to make OpenNebula a provider for Vagrant, and daemon for getting monitoring data from OpenNebula’s XML-RPC API and storing them to InfluxDB. Also, a very interesting Elastic load-balancing & high-availablitY Wired network Architecture. It comes packed with features, so if you are looking for complex network set ups is a must read. Moreover, a new version of knife plugin for OpenNebula is also available thanks to Megam.

A beta release of CLUES (energy management system for Cloud infrastructures) that supports OpenNebula was also released this month.

Unity Builds its Federated Cloud with OpenNebula

Unity Technologies is shaping a booming global games market. The Unity engine is far and away the dominant global game development software. More games are made with Unity than with any other game technology! And guess what? Unity uses OpenNebula to run their IaaS infrastructure to support their development services, among other things.

Unity Technologies contacted OpenNebula Systems, the company behind OpenNebula, due to its expert knowledge of OpenNebula, to jointly design and deploy Unity cloud infrastructure, dubbed uCloud. OpenNebula Systems offers this service through the Jumpstart packages, on their Basic and Advanced modalities, based on the different Open Cloud Reference Architecture corresponding types.

The basic principle that Unity applies to their infrastructure is the KISS approach, which is very much aligned with the OpenNebula design principle.

The Requirements

Unity Technologies offers its services globally, and as such required to deploy a cloud across three different data centers to serve EMEA, US and ASIA Unity users. The data centers were to be based on SoftLayer bare metal servers, and the users of the Cloud were expected to be able to access resources across these different data centers.

Regarding networking, a certain degree of federation was expected, particularly the ability to interconnect virtual machines from different data centers in different virtual networks. Unity Technologies suggested the use of network gateways to manage this interconnections, so the challenge was to integrate them in the OpenNebula workflow.

Other requirements were the use of Active Directory to authenticate users, and also to have a complete isolation between groups of users (that is, the workloads of one group of users should not affect the others), as well as hybrid access to public cloud providers, in particular SoftLayer and Amazon EC2, to be able to cloud burst Virtual Machine to them in case the allocated bare metal in SoftLayer cannot cope with the fluctuating demands.

The Design

OpenNebula Systems and Unity got to work right away, to deliver the best possible OpenNebula cloud design taking into account the requirements. Take a look at the picture to get a glimpse of the final design of uCloud.

unity

The use of Ceph was a no brainer, Unity used Ceph internally and OpenNebula Systems agreed right away since this cloud is expected to grow to a medium to large scale. This is aligned with the OpenNebula Advanced Reference Architecture, intended for clouds of this magnitude. Also, Ubuntu was preferred by Unity sysadmins, and given OpenNebula full support for it; the decision was arrived to easily enough as well.

Using OpenNebula federation capabilities solved right away the need to federate at the authentication level the different datacenters. The SoftLayer dedicated link low latency allowed the several instances of OpenNebula (one per data center) to communicate quickly enough to keep them synchronized and provide a top-notch user experience.

The need of serving different groups of people, with different needs in terms of physical and virtual resources, was also solved using the powerful OpenNebula provisioning model, by assigning physical resources to Virtual Data Centers, and providing access to them via Groups of users, to which virtual resources can be assigned.

Networking was trickier. The limitations of using only traffic encapsulated within VLANs imposed the use of VXLAN, which OpenNebula fully supports. Special integrations were made into OpenNebula to operate the Gateways as soon as a new virtual network is created; so new routes are created dynamically enabling the interconnection of different data centers virtual networks on demand. The OpenNebula flexible architecture proved that it is a great asset to solve complex designs.

Cgroups was the technology picked up for workload isolation, so VMs from one groups of users cannot eat up all the CPU resources if they are needed by another VMs. For memory, not allowing for over commitment was the decision.

The Result

uCloud is a state of the art cloud, with authentication and network federation, prepared to scale to support thousands and even millions of users as Unity Technology requires. Unity Technologies can arguably be given the credit of making the right call, contacting OpenNebula Systems, the creators of the technology, to push it to its limits to create a cloud infrastructure ahead of its time.

“We engaged OpenNebula Systems to verify our design thoughts and to speed up the deployment phase of our uCloud project.”, said Karsten Nielsen, IT Manager at Unity Technologies. “OpenNebula Systems is very professional and executed within the tight death-line the project was under. I am very pleased with the process and the result of the project.”


Karsten Nielsen will give a keynote about the uCloud infrastructure and OpenNebula at OpenNebulaConf2015 (Barcelona, October 20-22 2015). Register asap and save with very early Bird discount!.

OpenNebula Newsletter – April 2015

This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

Technology

An important milestone was reached this month with the publication of the Open Cloud Reference Architecture for Basic and Advanced cloud deployments. This Reference Architecture has been created from the collective information and experiences from hundreds of users and cloud client engagements. Besides main logical components and interrelationships, the document describes software products, configurations, and requirements of infrastructure platforms recommended for a smooth OpenNebula installation.

A maintenance release for Cotton Candy,4.12.1, was released this month by the OpenNebula Team. This release comes with several bug fixes found after the 4.12 release. These bug fixes covers different OpenNebula components, like for instance the scheduler, the Cloud View self service portal, Sunstone web interface, OpenNebula Core and several drivers (VM, Auth, Network). Besides the bug fixes mentioned above, 4.12.1 includes several improvements, like the ability to have VNC capabilities imported from vCenter VMs, a logrotate script for OpenNebula logs and, specially, the scheduler has been revisited to cope with large XML files. Now OpenNebula instances are able to manage even more VMs!

Also April saw the release of a new stable version of vOneCloud, the open replacement of vCloud to cloudify vSphere infrastructures. vOneCloud 1.4 comes with outstanding new features for vCenter resource management, like for instance the inclusion of Showback capabilities. The VDC model has been revisited to enable resource sharing easily among different groups, as well as the interfaces, in order to smooth the workflow of importing vCenter resources. The main highlight though is the addition of multi-vm management capabilities, enabling the management of services, including the ability to set up elasticity rules to automatically increase or decrease the number of nodes composing a service. vOneCloud is zero intrusive, try it out with without the need to commit to it!

Community

Technical posts are definitely our sort of thing. And if they come as detailed and rounded as this amazing piece showing how to install OpenNebula on HA with Ceph and IPoIB in CentOS, the better. Check it out for a awesome script laying out all the steps needed to reproduce this setup. Another example is this excellent post about securing noVNC connections for Sunstone, with detailed explanation on how to create your own CA for VNC connections.

In depth analysis of the OpenNebula technology by third parties is a great way to promote OpenNebula, giving users leeway to choose among the IaaS technology that better fit their needs. This blog post by OlinData is a great example.

Our community is always giving back, and that is the spirit of open source. For instance, people sharing his work to make other people’s life easier, is a great example of the health of OpenNebula community. This new addon enabling the integration of OpenNebula and StorPool broads the integration capabilities of OpenNebula. Also important this example of a nodejs boilerplate to interact with OpenNebula. Thanks!

As you may know, OpenNebula is participating in the BEACON project, flagship European project in federated cloud networking. You can check the profile of OpenNebula Systems in the project blog.

We run on feedback. Seriously, it is never enough. If you are doing an OpenNebula deployment we want to hear from you! As they say, through thick and thin. Have you just installed a Windows 10 VM using OpenNebula?. We want to hear from you!

vOneCloud 1.4 Released! Cloudify vSphere Infrastructures

We want you to know that OpenNebula Systems have just announced the availability of vOneCloud version, 1.4.

Several exciting features have been introduced in vOneCloud 1.4. The appliance that helps you turn your vSphere infrastructure into a private cloud generates daily reports that can be consulted by every user to check their resource consumption, with associated costs defined by the Cloud Administrator. The Virtual Datacenter provisioning model has been revisited to enable resource sharing easily among different groups, as well as to simplify configuration. The interfaces has also been improved to smooth the workflow of importing vCenter resources via the vOneCloud web interface, Sunstone. But probably most importantly, vOneCloud 1.4 add multi-vm management capabilities, enabling the management of sets of interconnected VMs (services), including the ability to set up elasticity rules to automatically increase or decrease the number of nodes composing a service, according to easily programmed rules that take into account the service demands.

Improvements were also in place for Control Panel, a web interface that eases the configuration of vOneCloud services and enables one click smooth upgrades to newer versions, introducing features to aid in the troubleshooting of the appliance.

The above features and components add to the already present ability to expose a multi-tenant cloud-like provisioning layer through the use of virtual datacenters, 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.

New Open Cloud Reference Architecture

We are excited to announce the release of the first version of the Open Cloud Reference Architecture. The OpenNebula Reference Architecture is a blueprint to guide IT architects, consultants, administrators and field practitioners in the design and deployment of public and private clouds fully based on open-source platforms and technologies. This Reference Architecture has been created from the collective information and experiences from hundreds of users and cloud client engagements. Besides main logical components and interrelationships, this reference documents software products, configurations, and requirements of infrastructure platforms recommended for a smooth OpenNebula installation. Three optional functionalities complete the architecture: high availability, cloud bursting for workload outsourcing, and federation of geographically dispersed data centers.

The document describes the reference architecture for Basic (small to medium-scale) and Advanced (medium to large-scale) OpenNebula Clouds and provides recommended software for main architectural components, and the rationale behind the recommendations. Each section also provides information about other open-source infrastructure platforms tested and certified by OpenNebula to work in enterprise environments. To complement these certified components, the OpenNebula add-on catalog can be browsed for other options supported by the community and partners. Moreover, there are other components in the open cloud ecosystem that are not part of the reference architecture, but are nonetheless important to consider at the time of designing a cloud, like for example Configuration Management and Automation Tools for configuring cloud infrastructure and manage large number of devices.

You can download a copy from the Jumpstart Packages page at the OpenNebula Systems web site.

Thank you!

OpenNebula Newsletter – March 2015

This Newsletter is intended to OpenNebula users, developers and members of the community, and compiles the highlights of the OpenNebula project during this last month and what are the planned actions for the upcoming months.

Technology

The OpenNebula team released this month the latest stable release, 4.12 Cotton Candy. This is a stable release and so a recommended update for all production deployments. Cotton Candy comes with several improvements in different subsystems and components. OpenNebula is now able to generate cost reports that can be integrated with chargeback and billing platforms, and also presented to both the administrators and the end users.

Moreover Virtual Datacenters have been redefined as a new kind of OpenNebula resource. Making VDCs a separate resource has several advantages, for instance they can have one or more Groups added to them. This gives the Cloud Admin greater resource assignment flexibility.

Other perks of upgrading your installation to 4.12 include SPICE support, the excellent addition of Security Groups -allowing administrators to define the firewall rules and apply them to the Virtual Machines-, support for VXLAN, huge improvements in vCenter -import running VMs, network management, new vCenter cloud view, VM contextualization support, etc -,system datastore flushing, and many more minor features and important bugfixes. As usual, the migration path has been thoroughly designed and tested so updating to Cotton Candy from previous versions is a breeze. No excuses then for not bringing your OpenNebula to the latest state of the art in cloud management platforms!
Also this month a new release of vOneCloud, 1.2.1, the open replacement for VMware vCloud, was made available to the general public, meaning that all users without an active support subscription are able to upgrade through the Control Panel with a single click. If you are using vOneCloud 1.2, take this chance to get an improved version, including VLAN support through Sunstone, notifications of new releases, better log display at the Control Panel and more. And if you are still not using vOneCloud give it a try! We’ve packed 1.2.1 in an OVA for your convenience, just to keep you without excuses again :)

Community

We certainly love our community, and it seems like you love us back! We are very proud of having Runtastic among our users, and when they explain why they chose us, we feel elated. They started with OpenNebula using the virtualization management features, and are continuously evolving towards more cloudy features. Way to go!

Our newly-launched machines are automatically included into Chef, and start doing their work within a minute

Good to know that OpenNebula clouds are expanding, this means they are healthy clouds. Like this one by bpsNode, expanding to Miami and Dallas. We are also excited by awesome user stories like this one featuring Altus IT with Lenovo delivering IT infrastructures in Croatia using OpenNebula. Way to go!

How good is your Russian? If you are fluent, enjoy the reasons of why Yuterra chose OpenNebula and Ceph for its Private Cloud. Moreover, fluent in German as well? Check out this OpenNebula webinar then.

Spreading the word is also something we deeply value from our community, hence we want to welcome the newly born Barcelona User Group! If you are in Barcelona, check it out, you won’t be disappointed. Also,we have like this example in FOSSAsia. And it is quite funny too, do not miss.

We love also this kind of feedback, how OpenNebula plays nice with other components in the ecosystem. Keeping our marketplace healthy and up to date is also kudos for the community, like this addition of ArchLinux to the catalog. Thanks!

A big thanks as well to all those members of the community that make possible to have a multi language Sunstone. This really foster adoption and we never could have done it without you! And last, but not least, it is very gratifying to see how OpenNebula helps build robust products like this one.
