You are migrating a legacy application from an on-premises data center to Google Cloud Platform (GCP) before its maintenance contract expires. The application's required network ports are unknown, and no documentation exists. How do you perform this migration without introducing security risks to your environment?
A
Migrate the application into an isolated project using a ג€Lift & Shiftג€ approach. Enable all internal TCP traffic using VPC Firewall rules. Use VPC Flow logs to determine what traffic should be allowed for the application to work properly.
B
Migrate the application into an isolated project using a ג€Lift & Shiftג€ approach in a custom network. Disable all traffic within the VPC and look at the Firewall logs to determine what traffic should be allowed for the application to work properly.
C
Refactor the application into a micro-services architecture in a GKE cluster. Disable all traffic from outside the cluster using Firewall Rules. Use VPC Flow logs to determine what traffic should be allowed for the application to work properly.
D
Refactor the application into a micro-services architecture hosted in Cloud Functions in an isolated project. Disable all traffic from outside your project using Firewall Rules. Use VPC Flow logs to determine what traffic should be allowed for the application to work properly.
