9 Years of OpenNebula!

nine

Today is the 9th anniversary of the founding of the OpenNebula open source project. We still remember the early days of OpenNebula, when we decided to start an open-source project to grow, distribute and support the software prototypes that we developed to support our research in virtualization management on distributed infrastructures. Yet here we are, nine years later, with one of the most successful projects in the open cloud ecosystem.

OpenNebula has grown into a widely-used user-driven project, with lots of examples of production use in academia, research and industry, over 100K downloads from the project repositories in the last year, more than 1,500 clouds connected to our marketplace, and large-scale infrastructures with tens of data centers and hundreds of thousands of cores. We are very proud of this growth as the only fully-open enterprise-ready management platform to build clouds.

None of it would be possible without your help, the hard work of thousands of users and contributors!

How We Use OpenNebula at Fuze

fuze_logo
Fuze, headquartered in Cambridge, MA with additional locations in North America, Europe, Asia and Australia, is a global, cloud-based unified communications platform that empowers productivity and delivers insights across the enterprise through a single unified voice, video, and messaging application. Fuze allows the modern, mobile workforce to seamlessly communicate anytime, anywhere, across any device. With Fuze, customers have a single global carrier network leveraging a resilient private cloud infrastructure and QoS-engineered network to deliver the best enterprise-class IP PBX voice service available.

Given the company’s record momentum and growth, scaling the private cloud infrastructure to meet the global expansions and growth is a key to its customers’ satisfaction. In mid-2015, we deployed OpenNebula as part of the Fuze Private Cloud Management Stack to achieve a continuously reliable growing private cloud spanning Fuze global infrastructure.

Here’s a quick look at the key features of OpenNebula that powered Fuze Private Cloud:

  • Simple and lightweight deployment and easily extendable being open source.
  • Self-Serve capability through GUI (Sunstone), CLI and API.
  • Multi-tenancy built-in providing segregation among internal workloads.
  • Supporting Agile DevOps by abstracting underlying infrastructure and supporting mainstream hypervisors besides public cloud bursting.
  • Automated VM Orchestration via contextualization that personalize instances on instantiation time.
  • Service Orchestration provided by OneFlow and OneGate that support multi-tier applications using role based instances. Besides, OneFlow has the ability to apply auto-scaling and recovery rule support based on either generic or custom application attributes pushed via OneGate.

Currently, Fuze Private Cloud has a central OpenNebula deployment in a data center in the eastern part of the US. This fault tolerant OpenNebula deployment is configured to connect and manage Fuze data centers across US East/ West, Australia, Asia, and Europe.

cloud_orchestration_v2

VMware ESXi/vCenter 6.0 is the dominant virtualization technology used across its data centers backed by SAN-based storage and we also use Amazon Web Services. OpenNebula leverages the SOAP API offered by each DC vCenter to manage the entire global cloud infrastructure and present it to the different engineering teams as an effective single orchestration pane of glass. In addition, we connected OpenNebula to a few AWS Virtual Private Cloud (VPCs) with dedicated tenancy that it bursts into where applicable.

We are currently running OpenNebula 5.0 which brought in enhanced user experience through Sunstone and renamed lifecycle states along a redesigned Marketplace. We will upgrade to OpenNebula 5.2 soon to make use of the upgraded hybrid cloud drivers.

Overall, the OpenNebula project has taken Fuze Global Private Cloud to the next level and continues to be a fundamental factor for continuous innovation and customer satisfaction.

New OpenNebula VCLOUD driver: Building Hybrid Clouds with VMware cloud providers

Based in its definition, the “Hybrid Cloud Computing” is a model which combines the use of multiple Cloud services across different deployment models, including combining the use of services of public cloud services private cloud outside or inside organization / institution.

Most companies and organizations have not been born in the “cloud”, a situation that often causes the cloud resources are to be connected to traditional systems or applications with some criticality and are usually located in their own premises. This type of architecture is the most common where the keys to their success pass take into account aspects such as integration capabilities, hyper-converged management, etc.

Cloud bursting is always welcome!

Today we are one_vcloudsharing exciting news about the expansion of the number of public clouds supported by OpenNebula to build hybrid cloud deployments. As a result of the collaboration between OpenNebula and CSUC, a new addon to support VCLOUD providers has been added to OpenNebula catalogue.

“With this addon, real hybrid architectures can use OpenNebula’s rich set of infrastructure management tools to manage cloud deployments across VCLOUD private, public and hosted cloud platforms.”

 

The driver is developed for Opennebula 5.x and VCLOUD 5.5 version and is released today to be available for testing. The integration has been carried out using the ruby_vcloud_sdk, which interacts with the vCloud Director API, enabling a complete control of the lifecycle of Virtual Machines in a transparent way within an OpenNebula cloud. Thanks to these new addon, private resources can be easily supplemented with resources from external providers to meet fluctuating demands.

https://github.com/OpenNebula/addon-vcloud-driver

Description

This addon gives Opennebula the posibility to manage resources in VMware vCloud infraestructures. It includes virtualization and monitoring drivers.

This driver is based on vCenter Driver and uses a modified version of ruby_vcloud_sdk.

Features

This addon has the following capabilities:

  • Deploy, stop, shutdown, reboot, save, suspend, resume and delete VM’s in the Virtual Data Centers hosted in vCloud.
  • Create, delete and revert snapshots of VM’s.
  • Change RAM and CPU values of VM.
  • It’s able to hot-attach and detach NICs to VM’s.
  • Automatized customization of the VMs instanciated.
  • Obtain monitoring information from the VDC, Datastore and VM’s.
  • In this development version we manage vApps with one VMs inside (A VM in OpenNebula equals a vApp with one VM in vCloud).
  • Each Virtual Data Center (VDC) in vCloud is managed as a Host in OpenNebula.
  • Import networks, hosts, templates and datastores hosted in vCloud using onevcloud script.

Managing Docker Hosts Deployments with Rancher and OpenNebula

Rancher is an open source software platform that enables organisations to deploy and manage container-based applications. Rancher supplies the entire software stack needed to manage containers in production using most of the commonly available container orchestration frameworks (Rancher Cattle, Docker Swarm, Kubernetes, Mesos).

Rancher has support for Docker Machine-based provisioning making it really easy to create Docker hosts on cloud providers. It creates servers, installs Docker on them, and configures the Docker client to talk to them. Using the Machine integration in Rancher, we can launch compute nodes directly from the Rancher UI.

Rancher recently has added support for docker-machine plugins, so it is possible to add Machine Drivers in order to create Docker hosts on any cloud providers.

This post will introduce Rancher and show how to launch OpenNebula Virtual Machines from the Rancher UI and provision them to run Docker compute hosts, which can then be used to run Docker containers. In the next steps we are going to install Rancher and use the OpenNebula docker-machine plugin to add virtual machine as hosts to Rancher environments.

Step 1 – Rancher Installation

Let’s first create a VM with docker, by using docker-machine

$ docker-machine create --driver opennebula rancher-server

Once the machine is created, we can install the rancher server

$ eval $(docker-machine env rancher-server)
$ docker run -d --restart=unless-stopped -p 8080:8080 rancher/server

After about a minute, your host should be ready and you can browse to http://rancher-server-ip:8080 and bring up the Rancher UI. If you deploy the Rancher server on a VM with access to the to the Internet, it’s a good idea to set up access control (via github, LDAP …). For more information regarding the Rancher installation (single node and HA setup and the authentication) you can refer to the official documentation

Step 2 – Adding OpenNebula Machine Driver

In order to add OpenNebula Virtual Machines as hosts to Rancher we need to add the docker machine plugin binary in the Admin Machine Drivers settings.

rancheradminmachinedrivers

A Linux binary of the OpenNebula machine driver is available at https://github.com/OpenNebula/docker-machine-opennebula/releases/download/release-0.2.0/docker-machine-driver-opennebula.tgz.

 

addmachinedriverOnce you added the machine driver, a screen with the OpenNebula driver should be active.

opennebulamachinedriver

Step 3 – Adding OpenNebula Hosts

The first time adding a host, you will see a screen asking you to confirm the IP address your Rancher server is available on, i.e. where the compute nodes will connect.

addhostsettings

Once you save the settings, you can proceed to create the first Rancher host.

selectopennebuladriver

Select the opennebula driver and insert at least the following options:

  • Authentication: user, password
  • OpenNebula endpoint: xmlrpcurl (http://one:2633/RPC2)
  • ImageID
  • NetworkID

and then you can proceed to create the host. After few minutes, when the creation process is complete, you should get a screen with the active host.

Step 4 – Deploy a container

To test the environment, you can select the host and add a container:

addcontainer

That’s all, we will be back soon with another post about the integration of Rancher and OneFlow to deploy multi-tier services on OpenNebula clouds. Stay tuned!

OpenNebula 5.2 ‘Excession’ Beta is Out!

The OpenNebula project is proud to announce the availability of the first beta release of OpenNebula 5.2 ‘Excession’. OpenNebula 5.2 (Excession) is the second release of the OpenNebula 5 series. A significant effort has been applied in this release to stabilize features introduced in 5.0 Wizard, while keeping an eye in implementing those features more demanded by the community.

As usual almost every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components. Also, new components have been added to enhance the OpenNebula experience.

hyperlinks_sunstone

One important new module is the IPAM subsystem. In order to foster SDN integration, a important step is being able to integrate OpenNebula with existing IPAM modules, in those cases where outsourcing of IP management is required in the datacenter. Fitting in the OpenNebula architecture design principles, the IPAM subsystem interacts with IPAM servers using drives, and as such a IPAM driver lets you delegate IP lease management to an external component. This way you can coordinate IP use with other virtual or bare metal servers in your datacenter. No default integration is provided, but rather to effectively use an external IPAM you need to develop four action scripts that hooks on different points of the IP network/lease life-cycle.

Another great addition in Excession is the ability to use group bound tokens. The goal is to be able to use OpenNebula for different projects, which are identified with different groups. For instance, the same user can use OpenNebula for “WebDevelopment” project and a “BioResearch” one, for instance. This user can request a couple of tokens tied to each of these groups. Upon login with the “WebDevelopment” token, she will only be seeing resources from that particular project, and all new resources (VMs, images, networks) will be created within that group, isolating them from the “BioResearch” group. This feature is available both in the CLI and Sunstone, with helpers and dialogs to create, maintain and use the tokens.

tokens_sunstone

All the OpenNebula drivers have been improved for robustness. For instance, a new default timeout (which is configurable) has been defined to identify hanging operations and kill crashed processes. In this regard, the EC2 drivers has also been thoroughly revisited, being updated to the v2 of the aws ruby gem, ensuring compatibility with all Amazon EC2 regions. Error handling has been improved as well in the EC2 driver, adding operation retries to circumvent those situations where the EC2 API is not consistent, and adding improved logging.

Sunstone is the face of OpenNebula for both administrators and users, and hence a constant target of enhancements to improve usability. Excession brings to the cloud table stabilized features that were introduced in the Wizard maintenance releases, like for instances advanced searches (that now are maintained regardless of tab switching), labels colors and ergonomics, improved vCenter dialogs and import tables (now with feature à la Gmail), hyperlinks to access resources displayed in the info tabs, and many other minor improvements.

labels_searches_sunstone

There are many other improvements in 5.2 like revamped group mapping in LDAP authentication -now being dynamic mapping-, rollback mechanism in failed migrate operations, significantly improved fault tolerant hook -to provide high availability at the VM level-, improved driver timeout, vCenter storage functionality wrinkles ironed out, more robust Ceph drivers -for instance, in volatile disks-, improved SPICE support, improvements in ebtables and Open vSwitch drivers, multiple CLI improvements -imrpved onedb patch, password handling in onevcenter command, default columns reviewed in all commands- and much more. As with previous releases, it is paramount to the prject to help build and maintain robust private, hybrid and public clouds with OpenNebula, fixing reported bugs and improving general usability.

This OpenNebula release is named after the Ian M. Banks novel, a recommended read, as well as having a fitting slang meaning, “something so technologically superior that it appears as magic to the viewer.”. We are confident that OpenNebula, if not really appearing as magic, at least solves elegantly your IaaS needs.

The OpenNebula team is now set to bug-fixing mode. Note that this is a beta release aimed at testers and developers to try the new features, hence not suitable for production environments. Feedback is more than welcome for the final release.

The OpenNebula project would like to thank the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.

The group token functionality and dynamic LDAP group mapping into OpenNebula groups were funded by BlackBerry in the context of the Fund a Feature Program.
