When migrating your on-premises solution to Google Cloud, you will need to maintain a connection between your on-premises systems and Google Cloud until the migration is complete. You can use Cloud VPN to create a secure, reliable connection between your on-premises environment and your Google Cloud Virtual Private Cloud (VPC) network.
To ensure that all your on-premises systems remain reachable during this period, you need to organize your networking in Google Cloud carefully. This involves selecting an appropriate IP address range for your Google Cloud VPC network.
Option A, which suggests using the same IP range on Google Cloud as you use on-premises, may lead to IP address conflicts and routing problems. This option is not recommended.
Option B suggests using the same IP range on Google Cloud as you use on-premises for your primary IP range and using a secondary range that does not overlap with the range you use on-premises. This option can work, but it is more complicated to set up and manage. Additionally, it may require modifying your on-premises routing tables to ensure that traffic is correctly routed to the correct network.
Option C is the simplest and most recommended approach. This option involves using an IP range on Google Cloud that does not overlap with the range you use on-premises. This approach avoids potential conflicts and routing issues, and it makes it easy to manage your networking configuration.
Option D, which suggests using an IP range on Google Cloud that does not overlap with the range you use on-premises for your primary IP range and using a secondary range with the same IP range as you use on-premises, can also work. However, it is more complex than option C and requires more careful management to avoid potential routing problems.
In summary, the best option for organizing your networking in Google Cloud when using Cloud VPN to maintain a connection between your on-premises systems and Google Cloud is to use an IP range on Google Cloud that does not overlap with the range you use on-premises (Option C). This approach simplifies your networking configuration and helps avoid potential conflicts and routing issues.
