How can ABC setup this scenario?
It is not possible to configure VPC peering since each department has a separate AWS account.
Setup VPC peering for the VPCs of Admin and Finance.
Setup VPC peering for the VPCs of Finance and HR as well as between the VPCs of Finance and Admin.
Setup VPC peering for the VPCs of Admin and HR
Explanations:
VPC peering can be configured between VPCs in different AWS accounts, provided the necessary permissions and configurations are set.
Only peering between Admin and Finance does not allow Finance to access HR’s employee data, which is essential for salary calculation.
This option allows Finance to access both HR’s data (for on-roll employees) and Admin’s data (for attendance), enabling complete salary calculations.
Peering between Admin and HR does not provide Finance access to HR’s data, making it insufficient for salary calculations.
