12th Japan CloudStack User Group Meetup MidoNet with scalable virtual router
The document presents an overview of CloudStack's default virtual router and the limitations it faces, including scalability issues and bottlenecks caused by VLAN configurations. Midonet is introduced as a solution that leverages a clustered network state database to enhance scalability and efficiency in network management. The presentation encourages discussion on potential features to further improve its integration with CloudStack.
