OpenNebula is an open-source toolkit to easily build any type of cloud: private, public and hybrid. OpenNebula has been designed to be integrated with any networking and storage solution and so to fit into any existing data center.

With OpenNebula you can transform your data center into a flexible and agile virtual infrastructure which dynamically adapts to the changing demands of the service workload.

OpenNebula orchestrates storage, network and virtualization technologies to enable the dynamic placement of multi-tier services (groups of interconnected virtual machines) on distributed infrastructures, combining both data center resources and remote cloud resources, according to allocation policies.

• Faster respond to infrastructure needs for services with dynamic resizing of the physical infrastructure by adding new hosts, and dynamic cluster partitioning to meet capacity requirements of services
• Centralized management of all the virtual and physical distributed infrastructure
• Higher utilization of existing resources with the creation of a infrastructure incorporating the heterogeneous resources in the data center, and infrastructure sharing between different departments managing their own production clusters, so removing application silos
• Operational saving with server consolidation to a reduced number of physical systems, so reducing space, administration effort, power and cooling requirements
• Lower infrastructure expenses with the combination of local and remote Cloud resources, so eliminating the over-purchase of systems to meet peaks demands

• Faster delivery and scalability of services to meet dynamic demands of service end-users
• Support for heterogeneous execution environments with multiple, even conflicting, software requirements on the same shared infrastructure
• Full control of the lifecycle of virtualized services management

• Fits into any existing data center thanks to its open, flexible and extensible interfaces, architecture and components
• Builds any type of Cloud deployment
• Open source software, Apache license
• Seamless integration with any product and service in the virtualization/cloud ecosystem and management tool in the data center, such as cloud providers, VM managers, virtual image managers, service managers, management tools, schedulers…
