If you want to make use of a virtual network, you must also configure the following components:
- Subnets
Subnets are a required part of a virtual network. You need TCP/IP subnets, which will designate addresses that are used on that network. Public and private address ranges are often used. When that’s not possible, addresses are often assigned by CSPs. Virtual networks can be segmented into one or more subnets. - Routers or Routing Tables
For any network, you must configure routers or routing tables on any virtual machine connected to the network so that packets can be routed appropriately. - DNS
DNS server addresses must be provided, either assigned by you or your CSP. - CSP Region or Zones
Virtual networks operating in different CSP regions must be specified. Doing so will also allow you to connect virtual networks in different regions. If needed, you can configure isolation between regions as well. - Traffic Filters
Configuring your traffic filters to the specifications of your security protocols will only allow approved traffic to pass through your network. Filters can be applied at NIC in virtual machines, to a subnet or to a cloud service. When necessary, you will do this with a network virtual appliance.
