A virtual network, or VNet, is a set of virtual machines (VMs) within which you can administer users and groups, security policies, and other policies. The VNet is a logical container for a set of resources. It enables Azure virtual machines (VM) to communicate with each other, and with the internet.
Within the VNet, you can assign resources. You can also segment the VNet into subnets. Each subnet in a VNet is a logical endpoint and is identified by an IP address. For more information, see
Azure documentation.
The VNet that you create for the Big Data Management implementation contains the following elements:
Various storage elements, such as ADLS and blob (or “general”) storage
Azure HDInsight cluster
Azure SQL databases, used for Informatica domain repositories
