The OpenNebula Project has just announced the first update of the fourth series 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 4.2 gives users and administrators an easy way to create, publish, share, and manage multi-tier cloud applications and define auto-scaling policies based on service level metrics and time schedule. The new service flow functionality converts an infrastructure cloud into a powerful environment for the execution of elastic business applications. OpenNebula 4.2 also includes improved VMware drivers, enhanced support for Xen4, a new simple provisioning tab for Sunstone, and other minor enhancements like datastore monitoring and more hooks.
