Question

Your company is migrating its workloads to Google Cloud due to an expiring data center contract. The on-premises environment and Google Cloud are not connected. You have decided to follow a lift- and-shift approach, and you plan to modernize the workloads in a future project. Several old applications connect to each other through hard-coded internal IP addresses. You want to migrate these workloads quickly without modifying the application code. You also want to maintain all functionality. What should you do?

  • BMigrate your DNS server first. Configure Cloud DNS with a forwarding zone to your migrated DNS

Explanation

Creating a VPC with the same CIDR ranges as your on-premises network and assigning each migrated workload the same static internal IP address allows you to maintain compatibility with the old applications that rely on hard-coded internal IP addresses. This solution ensures that the workloads can continue to communicate using the same IP addresses as they did in the on- premises environment, making the migration process smoother without modifying the application
