Internal Node Network

The above diagram only shows one cloud space:

• 3 virtual machines
• 1 virtual firewall
• 1 virtual switch, connecting the cloud space to the VXLAN (via the VTEP)

Color scheme:

• Red: virtual machines
  • The one that is labeled as fw_00ca is running the MikroTik RouterOS, turning the VM into a network router; there is one per cloud space, implementing various additional features, such as firewalling
  • The other ones in the picture are the virtual machines created for running end-user workloads
• Green: Open vSwitch virtual switches
  • The one that is labeled as space_00aa is the virtual switch of the cloud space VXLAN
  • public
  • gw_mgmt
  • vxbackend
• yellow: VXLAN tunnel endpoints (VTEPs)
