1. Network Topology
   1. Overview
      1. Network Topology visualization displays the topology of VPC networks and associated metrics
      2. It presents a single view of configuration information and real-time operational data
      3. It makes it easier to understand networking relationships, traffic paths and throughput between VM instances
      4. Lays out information in a graph format, where the nodes and lines represent entities and connections in the network
      5. Collects real-time telemetry and configuration data from Google's infrastructure to visualise resources
      6. Network Topology captures configuration information, metrics, and logs to infer relationships between resources in a project or in multiple projects
   2. Supported traffic
      1. Network Topology supports TCP traffic for certain traffic paths
      2. Traffic in a VPC network, such as traffic between VM instances and internal load balancers that are in the same network
      3. Traffic across peered VPC networks, such as traffic between VM instances and internal load balancers that are in peer VPC networks
      4. Traffic between Google Cloud and clients on the internet, and entities such as VM instances or HTTP(S) load balancers with public IP addresses
      5. Network Topology doesn't show traffic to or from Cloud VPN gateways, Interconnect connections, and managed services like Cloud Storage
