The OpenNebula project has just announced the availability of the beta release of OpenNebula 3.4 (Wild Duck). The software brings valuable contributions by many members of its community, and specially from Research in Motion, Logica, Terradue 2.0, CloudWeavers, Clemson University, and Vilnius University. This release is focused on extending the storage capabilities of OpenNebula, including support for multiple datastores. The use of multiple datastores provides extreme flexibility in planning the storage backend and important performance benefits, such as balancing I/O operations between storage servers, defining different SLA and QoS policies for different VM types or users, or easily scaling the cloud storage. OpenNebula 3.4 also features improvements in other systems, especially in the core with the support of logic resource pools, the EC2 API with the support ... (more)

OpenNebula 4.4 Beta Released

You are surely aware of the new features introduced in OpenNebula 4.2 Flame, and its focus to strengthen the most demanded and useful features. So now is time to move forward and implement new features demanded by our uses and that's why  the beta version OpenNebula 4.4 Retina is out for testing!  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 e... (more)

Advance Reservation of Capacity in Virtualized and Cloud Infrastructures

Haizea is an open source lease management architecture that OpenNebula can use as a scheduling backend. Haizea can also be run in simulation, providing a platform for experimenting with scheduling algorithms that depend on VM (Virtual Machine) deployment or on the leasing abstraction. Haizea uses leases as a fundamental resource provisioning abstraction, and implements those leases as virtual machines, taking into account the overhead of using virtual machines (e.g., deploying a disk image for a VM) when scheduling leases. Using OpenNebula with Haizea allows resource providers to... (more)

Researching Cloud Resource Management and Use: The StratusLab Initiative

Formed by CNRS/LAL, GRNET, SixSq Sàrl, and UCM, StratusLab is an informal, open collaboration that focuses on the use cloud technologies in research and commercial environments and on the management of cloud resources in those environments. The key issue with productive use of the technologies is effective management of the cloud resources. For broad adoption, cloud resources must be manageable with the same (or similar) techniques currently used by administrators of data centres. The initial activities of the collaboration will investigate how different management techniques ca... (more)

BoF Session on Cloud Computing API at Open Grid Forum 25

A BoF ("birds of a feather") session on Cloud Computing API was organized at Open Grid Forum 25 in Catania (Italy). The session focused on the charter and the creation of a Group inside OGF to work on the development of an API specification for the dynamic deployment, using an appropriate descriptor language, control and monitor of virtual machines. The scope of the specification will be all the high level functionality required for the life-cycle management of virtual machines which is needed to support automated service elasticity. The new specification will facilitate the in... (more)
