AWS Certified Solutions Architect Associate (SAA-C03) - VPC Peering

The video tutorial explains VPC peering, a method to connect two virtual private clouds (VPCs) in AWS. It compares VPC peering to WAN connections and highlights its non-transitive nature, meaning direct peering is required between each pair of VPCs for communication. The process of creating VPC peers involves initiating and accepting requests, ensuring unique CIDR blocks, and configuring routing and security group rules. Best practices include maintaining unique CIDR blocks for each VPC and tracking them using a spreadsheet.
