Below is a breakdown of bandwidth prices and network latencies on Google Compute Engine between virtual machines in the same zone, different zones, and different regions.
All VM's used for testing were of instance type f1-micro (1 vCPU, 0.6 GB memory) and used internal IP addresses.
GCE Bandwidth Prices
| Traffic type | Price (per GB) |
|---|---|
| Ingress | Free |
| Egress inner-zone | Free |
| Egress cross-zone in the same region | $0.01 |
| Egress cross-region within the US | $0.01 |
Note: If VM's span regions not within the US, bandwidth costs are significantly higher and billed at standard GCE Internet Egress rates.
GCE Network Latencies
| From zone | To zone | Type | Average ping rtt (latency) |
|---|---|---|---|
| us-west1-a (Oregon) | us-west1-a (Oregon) | inner-zone | 0.37 ms |
| us-west1-a (Oregon) | us-west1-b (Oregon) | cross-zone | 0.53 ms |
| us-west1-a (Oregon) | us-central1-a (Iowa) | cross-region | 34 ms |
| us-west1-a (Oregon) | us-east1-b (South Carolina) | cross-region | 67 ms |
Below are the full ping results of each test as well for completeness.
