Technology

Spring is slowly fading into summer (at least in the north hemisphere, that is), and meanwhile we are slowly (but hectically, make no mistake) cooking OpenNebula 5.0 to deliver a new release of the state of the art cloud management platform that you cherish.
Most seek after features are ready and now undergoing the relentless certification process:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  • vCenter storage management, including datastore selection, disk hotplug, vmdk creation, cloning and deletion; and full integration with the new Marketplace functionality. Also, vCenter resource pool selection for deployed VMs will be possible
  • fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula
  • revisited Sunstone style and interface changes (sneak peek), including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience
  • instantiate to persistent! Do not lose your VM changes, OpenNebula will create a new VM Template and preserver the disks of a VM, even if they are non-persistent

Check the full list of feature in the development portal.

Take a look at the sneak peak of the new Sunstone layout, do you like it? Let us know!

Let’s see what’ve been brewing in our amazing community this past month.

Our friends at LINBIT have published an excellent blog post describing the new DRBD manage add-on for OpenNebula to achieve High Availability in the storage backend. Very interesting, keep up the good work!

opennebula-diskless
CipherSpace have contributed an awesome blog post describing their experiences adapting OpenNebula to their needs to serve their customers. In particular, it is very interesting the extensions to build Private Virtual Datacenters. A must read!

With the flexibility provided by the OpenNebula platform, we were able to create a valuably different solution in the PvDC model with nearly all our effort in the conceptual development of what we wanted to offer and the testing of small adaptations of OpenNebula

Other contributions are also welcome! For instance this extension to the EC2 server authorization, a Devuan (for those init lovers!) OpenNebula ready image in the marketplace and also a new CoreOS image also in the marketplace. Also interesting this automated way of deploying OpenNebula in HA.
We want to thank the community for their active involvement in the OpenNebula forum. Helps for helping the newcomers and having such a good vibe!

New DRBD Manage add-on for Highly Available storage

DRBD backed storage is now integrated into OpenNebula with the new DRBD Manage addon.

DRBD provides transparent, real-time replication of block devices without the need for specialty hardware. DRBD Manage is an administrative tool which facilitates easy Logical Volume Management (LVM) and configuration files for multi-node DRBD clusters.

With the DRBD Manage driver, create each new image for your virtual infrastructure as a DRBD volume. Volumes intelligently balance the load on your storage nodes. Alternatively, assign volumes to the specific nodes that you want in use. This is a simple scale-out storage solution, supporting the capability to add new nodes to your storage cluster at any time. This, combined with the flexibility of LVM, allows DRBD to keep up with your ever-increasing storage requirements.

DRBD 9 and DRBD Manage allow transferring Images to Virtualization hosts via the DRBD Transport protocol. This allows images to be available nearly instantly on host nodes without requiring them to have storage space available.

Below is a diagram showing a simple OpenNebula cluster using the DRBD Manage Driver. This cluster has a Front End, two storage nodes, and a single virtualization host. The host has two images attached to it via DRBD Transport. Both images are deployed to double redundancy and are being replicated in real time across both storage nodes. This means that the failure of a single storage node will not disrupt IO on the host. All nodes have a local copy of DRBD Manage’s control volume.

opennebula-diskless

Features

  • Data redundancy
  • Automatic fail-overs if a storage node fails
  • Database and high I/O application compatible
  • Transfers images over the network with DRBD Transport
  • Quickly attaches images to VMs
  • Fast image clones

OpenNebula 5.0 is brewing and the team is closing new features and liking the overall feeling of the next major upgrade. We are set for a beta release of 5.0 this very same upcoming month of April, so stay tuned for the following:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  • vCenter storage management, including datastore selection and disk hotplug, a full integration with the new Marketplace functionality. Share VMDKs among OpenNebula instances! Also, vCenter resource pool selection for deployed VMs will be possible.
  • fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula
  • revisited Sunstone style and interface changes (sneak peek), including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience

There are more new bits and bobs, check the full list of feature in the development portal.
Continuing with the series of Docker integration posts, this past month this entry explained how to get Docker Swarms deployed with OpenNebula. The idea is to get Docker Swarm to build a cluster out of a collection of Docker Engine VMs deployed in OpenNebula with Docker Machine. Docker Swarm is native clustering for Docker, delivering many advantages, like scheduling, high availability, etc.

docker-swarm-opennebula
If you need professional support for your OpenNebula cloud, remember that OpenNebula Systems has extended the support services portfolio to include the Operating System of the virtualization nodes and the controller (which can be CentOS and/or Ubuntu), the hypervisor (libvirt and KVM), networking technologies as VXLAN/VLAN 802.1Q and Ceph as storage backend.

Community

The OpenNebula community never ceases to amaze us. Contributions to the common knowledge pool around OpenNebula deployments add huge value to the open source project. Several contributions were made this past month in this regard, let’s see the highlights.
A great addition is related to the LXCoNe addon with a very detailed and complete post. LXCoNE, a virtualization and monitoring driver for OpenNebula that comes as an add-on to provide OpenNebula with the ability to deploy LXC containers. It contributes to achieve better interoperability, performance and scalability in OpenNebula clouds. Right now, the driver is stable and ready for its release.
Also do not miss this post and contribution by TeleData, enabling the feed of monitoring data in the form of graphite metrics. Great work! And we blush with your words too!

In our opinion OpenNebula works like a charm. It is open and flexible. OpenNebula is one of the most mature, comprehensive and valuable Cloud-Stack available in the market

Overview (Zones + Clusters + Ressources)

And last but not least, our friends at LINBIT have contributed their OpenNebula driver for DRDB integration as an addon! This driver allows for highly available storage using DRBD9 + DRBD Manage in OpenNebula.

We are, as usual, thankful to have this wonderful community. Two thumbs up!

The OpenNebula team keeps working in OpenNebula 5.0, the next major upgrade that will incorporate a wealth of new features, keeping a smooth upgrade path. And no, this is no easy task folks. But we will make it happen.

OpenNebula 5.0 is a revolution around the corner. In a few weeks, a beta version will come out featuring the following highlights:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  • vCenter storage management, including datastore selection and disk hotplug, a full integration with the new Marketplace functionality. Share VMDKs among OpenNebula instances!
  • fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula

5.0 will also feature a myriad of interface changes, including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience and a long list of other features.

As you may have noticed, interest in Docker is surging. We see OpenNebula as the perfect IaaS support for Docker, and as such our strategy regarding integration of Docker ecosystem within OpenNebula is to follow a “container as a service” approach. This is containers within VMs, not replace KVM/ESX with containers to ensure we maintain strong multi-tenancy. First we want to integrate OpenNebula with Docker-Machine to be able to build a container environment within your cloud. This feature is very advanced, as you can see in blog post. The second step would be to integrate tightly with Docker Swarm to be able to create Swarms using the OneFlow component.

Community

Lots of exciting things are happening in the OpenNebula community. Collaborations, contributions, and yes! even praise. Let’s review the highlights.

LINBIT has developed a new set of drivers to give OpenNebula support for the excellent DRBD functionality. Check an informative demo in this video.

A new release of the Perl binding for the OpenNebula Cloud API (OCA) is also worth noting if Perl is your sysadmin scripting language of choice. No excuse to make all the chores automatically in your cloud infrastructure now!

A freshly brewed integration of OpenNebula with professional VDI platform has been announced by UDS Enterprise, to be available in the upcoming 2.0 release of their software.

Our friends at NodeWeavers never stop. Take a look at their new family addition. Cute is an understatement, and since it is based on OpenNebula, powerful another one.

World wide adoption of OpenNebula is a fact. If more proof is needed, this is an excellent one. OpenNebula has been translated to the Persian language! Check this out.

Overall, we are very proud of the OpenNebula community. OpenNebula won’t be half as good without you guys, keep it up!

OpenNebula Newsletter – January 2016

Check this Newsletter to find out the what kept us busy this month: latest developments, events and future plans for the upcoming months.

We are starting this 2016 willing to share with the OpenNebula community another chapter of excellent cloud management. If you, as we do, like planning ahead check the sponsorship opportunities for the next OpenNebula Conf 2016, due in October in Barcelona. Take a look also to the projected OpenNebula TechDays for this year.

Technology

The OpenNebula team, after the release of a new maintenance release for Great A’Tuin, the 4.14.2, is working around the clock on the next upgrade of OpenNebula, v5.0.
This new version will come packed with features and interface changes to iron out the wrinkles in the user experience, to make the experience managing and using an OpenNebula cloud even smoother. vCenter storage management (you are right, including datastore selection and disk hotplug), fully integrated virtual router management (including default and transparent HA for routers), marketplace datastore to easily import/export images to other OpenNebula clouds (we think this is a badass feature), Cloud View improvements, and a long list of other features. As a teaser see this blog entry about resource tagging in Sunstone to keep VMs, networks, images and templates perfectly organized.

Results from the last survey, aimed to understand the use of OpenNebula by the community, has been analyzed and published in the blog. After a careful filter, 190 organizations were chosen as a representative sample of the community. The main changes with respect to the last, 2014 survey are (read a more extensive report here):

  • 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 OS 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%

Community

The OpenNebula community never sleeps! Well, that may be an overstatement, but certainly when they don’t they contribute to the common knowledge as well as come up with cool integrations to enhance the already mighty power of OpenNebula clouds. Floating IPs for OpenNebula can be easily achieved now thanks to this nifty tool developed OpenNebula clouds, developed by the same authors as CloudVAMP and Docker drivers.

Billing is crucial for VPS providers, which will greatly benefit from this provisioning module for Blesta which can be plugged into OpenNebula infrastructures.
It is crucial for an open source project such as your favourite cloud management platform to receive its users feedback. As you may heard from us before (once or twice), our roadmap is defined using our knowledge of our user and community developer needs. This is why it is so important messages like this one, with very useful feedback to be taken into account in future OpenNebula releases. Thanks, keep up the good work!
