Google Cloud Platform has been integrated into Couchbase Server's Fully Managed offering, Capella, providing users with enhanced opportunities for hands-free maintainability. This integration introduces new challenges, particularly in the area of Private Networking, with VPC Peering recommended for secure and efficient communication between the Capella Cluster and Google Cloud. The setup process includes creating a Couchbase Capella Cluster and a VPC in GCP, ensuring that the CIDR blocks do not overlap, and configuring a Virtual Machine within the VPC. Users must establish a peering connection by enabling necessary services and permissions in Google Cloud, followed by executing specific commands through the GCloud command line tools to finalize the private network setup. The successful configuration is verified by ensuring private IP communication between the VM and the Couchbase Cluster, as confirmed by DNS resolution tests and traceroute checks. Resources for further learning and support are available through Couchbase documentation, forums, and community platforms.
