VPC Peering #
VPC’s can be connected via a VPC Peering connection. VPC peering has no aggregate bandwidth limits. This can be done across regions. VPC peering is a one-to-one relationship. Meaning that traffic cannot follow to another VPC via a newly linked VPC. If communication is needed you would have to create a mesh design. An environment with 10 VPC would have up to 100 peering connections or a full mesh. To get around this you can use a Transit Gateway to cut down on the peering connections but does have bandwidth tradeoffs.
