OpenNebula Newsletter – April 2015

This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

Technology

An important milestone was reached this month with the publication of the Open Cloud Reference Architecture for Basic and Advanced cloud deployments. This Reference Architecture has been created from the collective information and experiences from hundreds of users and cloud client engagements. Besides main logical components and interrelationships, the document describes software products, configurations, and requirements of infrastructure platforms recommended for a smooth OpenNebula installation.

A maintenance release for Cotton Candy,4.12.1, was released this month by the OpenNebula Team. This release comes with several bug fixes found after the 4.12 release. These bug fixes covers different OpenNebula components, like for instance the scheduler, the Cloud View self service portal, Sunstone web interface, OpenNebula Core and several drivers (VM, Auth, Network). Besides the bug fixes mentioned above, 4.12.1 includes several improvements, like the ability to have VNC capabilities imported from vCenter VMs, a logrotate script for OpenNebula logs and, specially, the scheduler has been revisited to cope with large XML files. Now OpenNebula instances are able to manage even more VMs!

Also April saw the release of a new stable version of vOneCloud, the open replacement of vCloud to cloudify vSphere infrastructures. vOneCloud 1.4 comes with outstanding new features for vCenter resource management, like for instance the inclusion of Showback capabilities. The VDC model has been revisited to enable resource sharing easily among different groups, as well as the interfaces, in order to smooth the workflow of importing vCenter resources. The main highlight though is the addition of multi-vm management capabilities, enabling the management of services, including the ability to set up elasticity rules to automatically increase or decrease the number of nodes composing a service. vOneCloud is zero intrusive, try it out with without the need to commit to it!

Community

Technical posts are definitely our sort of thing. And if they come as detailed and rounded as this amazing piece showing how to install OpenNebula on HA with Ceph and IPoIB in CentOS, the better. Check it out for a awesome script laying out all the steps needed to reproduce this setup. Another example is this excellent post about securing noVNC connections for Sunstone, with detailed explanation on how to create your own CA for VNC connections.

In depth analysis of the OpenNebula technology by third parties is a great way to promote OpenNebula, giving users leeway to choose among the IaaS technology that better fit their needs. This blog post by OlinData is a great example.

Our community is always giving back, and that is the spirit of open source. For instance, people sharing his work to make other people’s life easier, is a great example of the health of OpenNebula community. This new addon enabling the integration of OpenNebula and StorPool broads the integration capabilities of OpenNebula. Also important this example of a nodejs boilerplate to interact with OpenNebula. Thanks!

As you may know, OpenNebula is participating in the BEACON project, flagship European project in federated cloud networking. You can check the profile of OpenNebula Systems in the project blog.

We run on feedback. Seriously, it is never enough. If you are doing an OpenNebula deployment we want to hear from you! As they say, through thick and thin. Have you just installed a Windows 10 VM using OpenNebula?. We want to hear from you!

Outreach

The upcoming third edition of the OpenNebulaConf will be held in Barcelona this October 2015.You are still in time for getting a good price deal for tickets. Also, your company may be interested in the sponsorship opportunities for OpenNebulaConf 2015.

We have two Cloud Technology Days planned for US, in Chicago and Boston, for the end of June. We will publish the details in a few days. If there is anyone interested to host a TechDay in the east coast (in particular, we are looking for hosts in New York), drop us a line.

During the following months, members of the OpenNebula team will be speaking in the following events:

If you are interested in receiving OpenNebula training, check the schedule for 2015 public classes at OpenNebula Headquarters. Please contact us if your would like to request training near you.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.
