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.

2015 OpenNebula Cloud Architecture Survey Results

Executive Summary

This is the third survey of OpenNebula deployments since September 2012. The results of this voluntary survey were answered online between December 3, 2015 and December 11, 2015. While previous surveys were open for several months, responses in this survey were collected only over a period of one week because its goal is to have a snapshot on the architectural components of existing OpenNebula clouds in order to improve support for the most demanded infrastructure platforms and configurations.

Although several hundreds of organizations took part of the survey, we have only included in the analysis the 190 respondents that are using OpenNebula 4.x (latest series) and who we deem reliable because they have provided identification details that allow us to verify the answers of the survey. This is important given that our main aim is to have accurate and useful information about OpenNebula deployments. This Survey is not a market survey and does not express all OpenNebula deployments worldwide. Since the foundation of the open-source project in November 2007, OpenNebula has been downloaded more than 360,000 times from the project site (280,000 times since our first survey in September 2012 and 160,000 times since our latest survey in August 2014), not including other software repositories or third-party distributions.

Regarding the use of OpenNebula, the Survey shows 43% of overall deployments are in Industry and 13% in Research Centers. Most of organizations (80%) are in Europe, Russia or North America and use OpenNebula to build private clouds (93%). When asked about the type of workload, 73% said that they use OpenNebula for running production workloads.

Regarding the size of the clouds, 80% of deployments have fewer than 100 nodes and 10% of deployments have more 500 physical nodes. 51% of deployments consist of more than one OpenNebula zone and 5% run more than 10 zones. Among the advanced components offered by OpenNebula, High Availability at 73% is the most widely used, in correspondence with the predominant production usage of OpenNebula.

Regarding the building blocks of the cloud, KVM at 79% and VMware vCenter at 37% are the dominant virtualization platforms, and CentOS at 44% and Ubuntu at 40% are the most widely used linux distributions for OpenNebula clouds. The preferred choices for the storage back-ends are shared FS and Ceph at 60% and 40% respectively. Regarding networking, most of the deployments, 45%, use the Standard Linux Bridge for network configuration, 35% use 802.1Q, and 33% use Open vSwitch. 44% of deployments use the hybrid cloud functionality offered by OpenNebula. Amazon EC2 at 30% and Microsoft Azure at 16% are the most widely used public clouds.

In comparison to previous survey findings in 2014, there have been some changes:

  • 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 operating systems 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%.
  • The use of LVM as storage solution decreases from 22% to 12%.

On the whole, OpenNebula continues to be loved by its users for its flexibility, 82%, simplicity, 80%, and openness, 72%. These results are aligned with our our mission — to become the simplest cloud enabling platform — and our purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure.

We would like to thank all respondents that took part in the survey!

A. About the Organization

43% of respondents indicated that they work for industry, while 13% work for research centers. These are similar to previous survey results.

Type_Organization

Type of Organization

 

50% of deployments are in Europe and Russia. This means a small reduction compared with previous survey data where the number of deployments in Europe and Russia was 54%. The number of deployments in North America grows from 20% to 30%. 80% of respondents are located in Europe, Russia, and North America.

Geographic

B. About the Type of Cloud

93% of respondents are running a private cloud for internal operations, while 34% are running a public cloud to offer utility services. Compared with previous survey data in 2014, the number of public clouds decreases from 40% and the number of private deployments increases from 84%.

Type

Type of Cloud (people may select more one checkbox)

 

73% of respondents are running non-critical environments or peripheral installations for running testing or development applications, while 73% are using the cloud for running production workloads. We see that OpenNebula is increasingly mature, with more deployments moving into production stage as compared with prior surveys data, from 42% in 2012 and 62% in 2014.

Workload
