By hybrid connectivity, we mean connectivity between GCP and your on-premises data center. It is important if you want to connect through a secure channel to GCP and not simply traverse the internet. There are a number of ways this connectivity can be achieved. The method you choose will depend on your reliability, bandwidth, and latency requirements.
Now, let's have a look at some possible hybrid connectivity options, that is, VPN Interconnect and peering.
