With Oracle Solaris network virtualization features, you can achieve goals such as the following:
Workload consolidation
Consolidating multiple workloads into a single system is a common practice in large deployments.
Private virtual networks
Virtualizatoin enables you to create private virtual networks for the following purposes:
Security – Create a private virtual network behind a virtual firewall to better insulate virtual machines from the physical network and also to better insulate the physical network from the virtual network.
Testing and simulation – Create a private virtual network within a box to test different features or simulate the behavior of a feature under a given network load before actually implementing that new feature or network configuration.
Network consolidation – Consolidate multiple hosts, network functions, and various network devices such as routers, firewalls, load balancers, and so on, within a box.
Cloud networking
A cloud architecture is a network administration approach that uses a utility computing model to deploy workloads. This architecture is highly dynamic where multiple tenants share the same cloud and therefore must be isolated from one another. Cloud administrators can easily provision, control, and observe per-tenant virtual networks that are isolated and secure.
