Midokura's MidoNet is a distributed, decentralized network virtualization product that is purpose-built for Infrastructure-as-a-Service (IaaS) clouds, such as OpenStack and CloudStack. MidoNet allows end users to build complex and arbitrary network topologies in their cloud environments without requiring more than IP connectivity from the physical network. MidoNet offers a virtual device approach, which includes devices such as switches, routers, firewalls, and load balancers and the ability to connect these devices in an arbitrary way. L2 and L3 layer isolation is also provided for the security-minded user. MidoNet design is distributed and decentralized, so it can scale horizontally as more capacity is needed.
