Dear Community, This is the official announcement of OpenNebula 4.4 Retina Beta (4.3.80). This release includes important features that meet real demands from production environments, with a focus on optimization of storage, monitoring, cloud bursting, and public cloud interfaces.
OpenNebula Retina includes support for multiple system datastores, which enables a much more efficient usage of the storage resources for running Virtual Machines. This feature ships with different scheduling policies for storage load balancing, intended to instruct OpenNebula to spread the running Virtual Machines across different storage mediums to optimize their use. This translates in the ability to define more than one disk (or other backend) to hold running VMs in a particular cluster. Monitorization subsystem in OpenNebula underwent a major redesign as well, effectively switching from a pulling mechanism to a pushing model, with the implications in scalability improvements. An important effort has been made in the hybrid cloud model (cloud bursting). Using the AWS API tools have been deprecated in favor of the new Ruby SDK released, which allows the support of new AWS mechanisms like for instance IAM. Also, now is possible to fully support hybrid VM templates. Moreover, the AWS public cloud interface implemented by OpenNebula has been revisited and extended to support new functionality, as well as improved so the instance types are offered to the end user from OpenNebula templates. We are now working on two more features to be added post-beta: support for CephX and native KVM support for glusterFS, the rest of the code is in feature freeze and just bug fixes will be added. Note that this is a beta release aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release. As usual OpenNebula releases are named after a Nebula. The Retina Nebula (IC 4406) is a planetary nebula near the western border of the constellation Lupus, the Wolf. It has dust clouds and has the shape of a torus. Behold the clouds with your Retina, they just look nicer ;) The OpenNebula Team LINKS * Complete Release Notes: http://opennebula.org/software:rnotes:rn-rel4.4beta * Download: http://downloads.opennebula.org/ * Documentation: http://opennebula.org/documentation:rel4.4 -- OpenNebula - Flexible Enterprise Cloud Made Simple -- Constantino Vázquez Blanco, PhD, MSc Senior Infrastructure Architect at C12G Labs www.c12g.com | @C12G | es.linkedin.com/in/tinova -- Confidentiality Warning: The information contained in this e-mail and any accompanying documents, unless otherwise expressly indicated, is confidential and privileged, and is intended solely for the person and/or entity to whom it is addressed (i.e. those identified in the "To" and "cc" box).
