A company in the United States (US) has acquired a company in Europe. Both companies use the AWS Cloud. The US company has built a new application with a microservices architecture. The US company is hosting the application across five VPCs in the us-east-2 Region. The application must be able to access resources in one VPC in the eu-west-1 Region. However, the application must not be able to access any other VPCs. The VPCs in both Regions have no overlapping CIDR ranges. All accounts are already consolidated in one organization in AWS Organizations. Which solution will meet these requirements MOST cost-effectively?
