+In Azure, VNet peering and connected groups are two methods of establishing connectivity between virtual networks (VNets). While VNet peering works by creating a 1:1 mapping between each peered VNet, connected groups use a new construct that establishes connectivity without such a mapping. In a connected group, all virtual networks are connected without individual peering relationships.  For example, if VNetA, VNetB, and VNetC are part of the same connected group, connectivity is enabled between each VNet without the need for individual peering relationships.
