Description: This pattern deploys a fully private serverless architecture using API Gateway Private Custom Domain, Lambda, SQS, DynamoDB, and SNS, ensuring secure communication within a VPC and eliminating public internet exposure. The API Gateway is configured with a private custom domain secured by an ACM certificate and accessible only through a VPC endpoint. Route 53's private hosted zone ensures that DNS resolution occurs exclusively within the VPC.
