OpenNebula 4.4 Retina bringing simplicity to enterprise cloud computing

MADRID, SPAIN: The OpenNebula Project is excited to announce the nineteenth stable release of its widely deployed OpenNebula cloud management platform, a fully open-source solution for data center management and enterprise cloud computing.

With a sysadmin-centric approach, OpenNebula is the open operating system of choice in the converged data centre, combining a powerful virtualization manager that supports traditional IT features such as fault tolerance and failover, with the dynamic provisioning, elasticity and multi-tenancy of the enterprise cloud.

OpenNebula 4.4 Retina includes support for multiple system datastores, which enables the definition of scheduling policies for storage load balancing. The monitoring subsystem has switched from a pulling mechanism to a massively scalable pushing model, being now able to monitor hundreds of thousands of VMs in a few minutes.

An important effort has been also made in enhancing the support for cloud bursting to Amazon, enabling a transparent offload of computing power whenever the local infrastructure cannot cope with the demand. Moreover, the Amazon EC2 and EBS interfaces implemented by OpenNebula have been revisited and extended to support new functionality.
