Question 1

What's the difference between Cloud VPN Gateway and Cloud Interconnect?

Accepted Answer

Cloud VPN Gateway (Cloud VPN) uses encrypted IPsec tunnels over the public internet. It’s typically faster to set up and works well for moderate bandwidth needs. Cloud Interconnect is a dedicated physical connection to Google’s network (not over the public internet), usually offering higher throughput and more consistent latency, but it takes longer to provision and often costs more. Many organizations use Cloud VPN as a primary option for smaller needs or as a backup to Interconnect.

Question 2

When should I use Cloud VPN Gateway?

Accepted Answer

Use it when you need a secure, encrypted connection between your on-premises network (or another cloud) and a Google Cloud VPC, especially when you want quick setup, don’t need extremely high bandwidth, or want a cost-effective hybrid connection. It’s also commonly used as a backup path for Cloud Interconnect, or for temporary connectivity during migrations.

Question 3

How much does Cloud VPN Gateway cost?

Accepted Answer

Costs typically include (1) hourly charges for the VPN gateway resources (for example, HA VPN gateways), and (2) network egress charges for traffic leaving Google Cloud. Your on-premises VPN device and internet connectivity also have their own costs. Pricing varies by region and usage, so the main factors are gateway hours, amount of data transferred, and where the traffic is going.
