Oracle Solaris provides a complete OpenStack distribution. OpenStack is the open source cloud computing software that provides comprehensive self-service environments for sharing and managing compute, network, and storage resources in the data center or multitenant cloud environment through a centralized web-based portal. OpenStack is integrated into all the core technology foundations of Oracle Solaris 11, so you can now set up an enterprise-ready private cloud infrastructure as a service (IaaS) environment in minutes.
OpenStack Neutron provides network virtualization. EVS in Oracle Solaris implements OpenStack Neutron APIs to provide network connectivity between VMs either through VLANs or VXLANs. For more information, see Installing and Configuring OpenStack (Havana) in Oracle Solaris.
