-The maximum bandwidth per "VPC attachment", AWS Direct Connect gateway, or peered transit gateway connection Up to 50 Gbps

with Transit Gateway, Maximum bandwidth (burst) per Availability Zone per VPC connection is 50 Gbps. VPC peering has no aggregate bandwidth. Individual instance network performance limits and flow limits (10 Gbps within a placement group and 5 Gbps otherwise) apply to both options. Only VPC peering supports placement groups. Reference:

Multi-VPC design. AWS recommends segmenting networks at the VPC level. In this approach, workloads are grouped together at the VPC level instead of the subnet level. All traffic between VPCs will be inspected by network security virtual firewalls at each VPC or at a shared VPC. Design patterns such as Transit VPC or AWS Transit Gateway can be used to achieve this in an automated and scalable fashion.

GCP Limitations: You cannot add or remove network interfaces from an existing VM.
