VPC Peering
Explore how VPC peering facilitates secure communication between VPCs using private IP addresses within and across AWS regions. Understand the setup process, traffic rules, and the non-transitive, one-to-one nature of peering connections. Learn to monitor network security with VPC flow logs at multiple levels and how to use them for compliance and traffic analysis.
We'll cover the following...
VPC peering is a feature that allows us to connect different VPCs so that their resources communicate with each other such as they reside in the same VPC. These resources communicate with each other through private IP addresses over the AWS global network to route traffic between VPCs. Therefore, VPC peering doesn't use the public internet and is a highly secure mode of connection.
VPC peering has two modes of connection:
Intra-region connection: It allows us to connect VPCs within the same region. We need to ensure ...
