    • Integrate neW storpool features
      Multi site
15:30 – 16:00: Disaster Recovery solution with OpenNebula and StorPool

Boyan Krosnov,Chief of Product of StorPool

In this talk we’ll explore a DR solution based on OpenNebula, developed by StorPool and deployed at a financial services organization. This solution represents a break-through for OpenNebula and StorPool technologies in a very conservative sector.
The solution uses two OpenNebula orchestrators using the federated identities scheme and two StorPool storage systems connected to each other with an encrypted site-to-site link.
It highlights how easy it is to extend OpenNebula to perform additional functionality, even without modifying the upstream OpenNebula software.

16:30 – 17:00: Demo OpenNebula and VMware vCenter

Javi Fontán, OpenNebula Developer

In this demo OpenNebula will be shown managing a vCenter infrastructure.

Make sure you register soon as the seats are almost gone! There will be a live stream of the event so stay tuned for more information.

Hybrid Clouds: Dancing with Virtual Machines

Today, the model of hybrid cloud comes under the eyes of a lot of organizations. The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer. The case of CSUC, acting as Opennebula powered cloud provider and at the same time as user of external IaaS and PaaS services, is analyzed sharing its first experiences in the way to archive a real multicloud architecture.

hybrid_cloud

Figure 1- The Hybrid Cloud, acts as a slicing bridge.

The majority of organizations have not been born in the “cloud”, situation that produces a lot of cases where the cloud resources have to interact or to be connected to traditional systems and applications with some criticality and usually are situated in its own dependencies. This kind of architecture is the most usual, where the main keys for its success go through to be aware about things like the integration capabilities or the impact in the organization roles where could exist different interpretation of the same concept.

For a solutions designer the model has to offer flexibility, speed and capacity. In the case of the infrastructure team it’s easy to think that more “different things” have to be managed. The business development staff will ask if it will be more expensive and which is the value that the hybrid model will contribute.

From the IT infrastructure perspective, when a public cloud provider is selected/procured, a good approach to start with in the adoption of hybrid cloud model is to focus in these first three challenges.

  • Networking: to extend your network layers with capable “dedicated” circuits provision with bandwidth control outside and inside public cloud provider(s).
  • Management: to consolidate a truly global infrastructure management platform through a cloud orchestrator and its cloud bursting capabilities.
  • Security: to extend to public cloud provider current security layers (platforms, tools, policies,…) under the current organizations umbrella.

Definitely, the model or architecture to implement will be different depending on each case where the applications/services have a lot to say and have to be listened. The pure reality is that nowadays almost all the organizations work in two different speeds and this is something that the technology departments have to work with. Some very changing environments like web and mobile applications and other more robust systems associated to critical processes with high levels of stability and security. A real cloud hybrid model should support the combination of this two speed ecosystems maintaining its specific dependences and needs.

The CSUC use case: driving to a hybrid cloud architecture

CSUC, in these last two years has worked in these challenges with some actions that are transforming roles, the management models at ICT infrastructure level, the way of services provision, etc.

The first action was to start a procurement process to provision the first IaaS provider with the idea of infrastructure and services optimization in a new model of payment by use. In parallel as RREN, the adoption of a orchestrator role with its own cloud management platform (Opennebula based) to manage distributed resources in a real multicloud environment. The network design, the unified management and security conditioned the strategy.

Regarding the new external cloud provider and after an a intense procurement process, the company Nexica  resulted adjudicator for four years of the provision of IaaS services for Catalan Universities and CSUC.

Nowadays, the catalan institutions who are using this shared service are:

What work has already been done:

  • First IaaS provider procurement process.
  • Service catalog, service-level agreements and governance.
    Architecture redefinition.
  • RREN extended to the provider: Layers 2&3.
  • A new Opennebula cloud bursting driver was developed (VCLOUD compliance)
  • Integration of CSUC opencloud orchestrator.
  • Deployment of first production services.

If you are interested to see more details, please contact with us.  This initiative will be presented in the next TNC17 , the annual Géant congress, at Linz – Austria [31/5/2017] (see the full paper here).

TechDay in Prague March 7th

In less two weeks we are going to have our first TechDay this year. We want to thank our friends at CESNET for organizing it!

This time the TechDay is a little bit different and instead of talks we will have an open session where people can ask questiosn on how to use OpenNebula. Experienced users from CESNET will answer your questions. We are still having the tutorial in the morning for people that never used OpenNebula.

If you want to know more head to the TechDay page or head directly to the registration page, it’s free!

LXDoNe – Lightweight Virtualization for OpenNebula

Operating system (OS) level virtualization is a technology that has recently emerged into the cloud services paradigm. It has the advantage of providing better performance, elasticity and scalability than para-virtualization or full virtualization. This happens because HVM hypervisors need to emulate hardware and use a new kernel for each virtual machine that will be deployed. OS level virtualization follows a completely different approach. This technology allows you to share the kernel with the virtual portion of the system, in other words, the kernel is the same for the host and the “virtual machines” running on top of it. A container is a virtual environment, with its own process and network space that makes use of Linux kernel Control Groups and Namespaces to provide hardware isolation. Containers have their own view of the OS, process ID space, file system structure and network’s interfaces. Since they use kernel features, and there’s no emulation of hardware at all, the impact on performance is minimal.

LXD is not just an Operating system level virtualization technology, it’s a hypervisor technology for containers. This means LXD containers look and act like virtual machines, but have the lightweight performance and scalability of process containers [1]. LXD has proven dramatic improvements over HVM hypervisors such as KVM [2] and ESX [3] in aspects such as density, speed and latency. 

LXDoNe-logo

LXDoNe is an add-on that allows OpenNebula  to manage LXD containers. It contains a virtualization and monitoring drivers. Right now it’s deployed in Universidad Tecnológica de La Habana José Antonio Echeverría‘s Data Center, alongside with KVM for special cases that implies a different kernel. We are actively working on adding more features and any reported bug will be prioritized by our team.

Features and Limitations.

Right now, the driver has the following features:

  • Life cycle control: deploy, shutdown, restart, reset, suspend and resume containers.
  • Support for Direct Attached Storage (DAS) filesystems such as ext4 and btrfs.
  • Support for Storage Area Networks (SAN) implemented with Ceph.
  • Monitor hosts and containers.
  • Limit container’s resources usage: RAM and CPU.
  • Support for VNC sessions.
  • Deploy containers with several disks and Network Interface Cards (NICs)
  • Support for dummy and VLAN network drivers.
  • Full support for OpenNebula’s contextualization in LXD containers (using special LXD images that will be uploaded to the market).

Features we are currently working on, most of them should be ready in the next couple of weeks:

  • Migration.
  • Snapshots.
  • Hot attach and detach NICs and disks.
  • LVM support.
  • Bandwidth limitation.

Known bugs:

  • VNC session only works with the first machine on each node. This is the reason for this behavior.

The driver has been released here. You can check there the installation guide for start using LXD with OpenNebula.

Contributions, feedback and issues are very much welcome by interacting with us in the GitHub repository or writing a mail:

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!
