A global pharmaceutical company operates a hybrid cloud network. Its primary AWS workloads run in the us-west-2 Region, connected to its on-premises data center via an AWS Direct Connect connection. After acquiring a biotech firm headquartered in Europe, the company must integrate the biotech’s workloads, which are hosted in several VPCs in the eu-central-1 Region and connected to the biotech's on-premises facility through a separate Direct Connect link. All CIDR blocks are non-overlapping, and the business requires full connectivity between both data centers and all VPCs across the two Regions. The company also wants a scalable solution that minimizes manual network configuration and long-term operational overhead. Which solution will best meet these requirements?
