The “Cloud” Need Not Be A Commodity

CipherSpace has a heritage of providing managed ICT infrastructure and services to clients who need customized “enterprise-quality” solutions on small to medium-sized business scales. Historically this demanded versatility, so that we could both provide each client with the right solutions for them and also with the expertise and judgment to guide them in the choice of their best solutions. As a consequence, we have used many approaches to virtualization over the years: FreeBSD Jails, Parallels, VMWare ESX/ESXi, Citrix XenServer, and Linux KVM, as well as working with others in non-production testing and evaluation. Because we have diverse clients with services in technically close proximity to each other, security has always been a critical focus of our work. We also have a strong preference for open source software, based not only on the obvious cost advantage but also for its adaptability and more transparent (and historically better) security. We’re not OSS purists in any sense, but openness is an important feature of many solutions we offer, as is the availability of commercial support for critical instances of critical tools, both for ourselves and our customers.

It became clear to us in 2011 that “Cloud” architectures were maturing in a way which made it imperative for us to create our own suite of solutions that would serve our clients differently and better than what they could get from the commodity sector. Read more

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.

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

About NodeWeaver

NodeWeaver is a new kind of hyperconverged appliance-bringing together storage, networking and virtualization, completely self-managing and designed to be simple to operate and exceptionally reliable. We have chosen from the start to take advantage of the OpenNebula orchestrator as our main component, a choice driven by its simplicity, reliability and its open design and development process. Our choice has been demonstrated, over and over, an excellent one: OpenNebula simplicity has been extremely appreciated by our customers, and the modularity of its architecture substantially reduced the complexity of adapting and extending it. In three years of experimentation, and several mission critical deployments, OpenNebula has exceeded all our expectations.

We are pleased to announce the agenda for the upcoming Cloud Technology Days that will be held in April in USA and Canada:

They feature a 4-hour hands-on tutorial in which you will learn how to install and configure an OpenNebula Cloud from scratch, and presentations from community members and users.

The event in Dallas, TX is hosted by Improving, a complete IT services firm, offering training, consulting, recruiting, and project services. The event is also sponsored by Digital Ocean, a cloud infrastructure provider focused on simplifying web infrastructure for software developers. In addition to the hands-on tutorial that will be held in the morning we will have the following talks during the afternoon:

  • Javier Fontán from OpenNebula Systems will talk about Customizing Virtual Machine Images and Docker Machine and Swarm on OpenNebula

 

The event in Toronto, Canada is hosted by Canada151 Data Centers, which provides carrier neutral, highly redundant Colocation and Disaster Recovery services from their West Toronto facility.  The event is also sponsored by Solgenia, a Cloud technology provider specializing in SaaS, PaaS and IaaS solutions. In addition to the hands-on tutorial that will be held in the morning we will have the following talks during the afternoon:

The OpenNebula monthly newsletter, with latest developments, events and future plans for the upcoming months from the OpenNebula project. Read this newsletter to keep up to date with your favorite Cloud Management Platform.

The OpenNebula Conf 2016 is due in October in Barcelona, Spain, and the Call for Speakers is now Open!. If you are a OpenNebula practitioner, user, architect, devop, admin or developer and have something to share, we welcome your submission. You might be also interested in taking a look at the sponsorship opportunities. Also check out the projected OpenNebula TechDays for this year in case one is close to your location. Upcoming TechDays in April will be held in Dallas,Toronto and Cambridge. Also, there is some (but just a few!) seats left for the OpenNebula course OpenNebula Systems is giving in Cambridge.

Technology

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.

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!
