Topology Instance#

The CyberRangeCZ Platform Terraform Client transforms a Topology Definition (user-defined topology) with the Topology Instance Management sub-infrastructure into the Terraform Template, which is then used by Terraform to create a virtual infrastructure we call a Topology Instance.

Note

For clarity reasons, there are missing links from man-network to the left Router and left Host.

Topology Instance Management#

Every Topology Instance is created with management sub-infrastructure, which consists of the following.

  • MAN (Management Access Node): The only node connected to the network outside the Topology Instance.

  • man-network (management network): All nodes in the Topology Instance are connected to this network so that every node is accessible from MAN and can be configured through it. CIDR of this network should be specified in the configuration.
