Google Cloud published a blog post detailing the routing options available for VPC networks. Instead of relying on physical routing devices, Google Cloud uses a distributed approach that offers scalability and flexibility. The blog post explains the different types of routes, including system-generated routes, custom routes, VPC Network Peering, and Network Connectivity Center routes.
I found the section on "Policy-based routes" particularly interesting. These routes allow you to route traffic based on the destination IP address, IP protocol, and source IP address, providing granular control over traffic flow. They can be used to insert appliances such as firewalls into the network traffic path, enhancing the security posture.
Furthermore, the blog post provides a useful decision table that summarizes different routing scenarios and the corresponding routing options. This is a valuable resource for anyone designing or managing VPC networks on Google Cloud.
Overall, this Google Cloud blog post is a must-read for anyone looking to understand the routing options available in Google Cloud. It provides a comprehensive overview of the topic and includes practical examples and tips. I highly recommend it to anyone responsible for Google Cloud networks.
