A pharmaceutical company operates its infrastructure in a single AWS Region.The company has thousands of VPCs in a various AWS accounts that it wants to interconnect.
Which AWS service or feature should the company use to help simplify management and reduce operational costs?
VPC endpoint
AWS Direct Connect
AWS Transit Gateway
VPC peering
Explanations:
VPC Endpoints allow private connections between VPCs and AWS services without an internet gateway, but they do not enable VPC-to-VPC connectivity directly.
AWS Direct Connect provides a dedicated network connection from on-premises to AWS, not interconnectivity across multiple VPCs in the same region.
AWS Transit Gateway simplifies VPC interconnection by acting as a hub that can connect thousands of VPCs, reducing complexity and management costs.
VPC Peering allows direct communication between two VPCs, but scaling to thousands of VPCs would be complex and costly to manage.
I surmise that the answer is:
AWS Transit Gateway
