# [Comparing bandwidth prices and network latency between Google Compute zones and regions](/content/posts/comparing-bandwidth-prices-and-network-latency-between-google-compute-zones-and-regions/index.html) Feb 17, 2017 Justin Keller Below is a breakdown of bandwidth prices and network latencies on **[Google Compute Engine](https://cloud.google.com/compute/)** 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](https://cloud.google.com/vpc/network-pricing#internet_egress). ## 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. **us-west1-a to us-west1-a (inner-zone)** ```shell PING 10.138.0.2 (10.138.0.2) 56(84) bytes of data. 64 bytes from 10.138.0.2: icmp_seq=1 ttl=64 time=1.16 ms 64 bytes from 10.138.0.2: icmp_seq=2 ttl=64 time=0.298 ms 64 bytes from 10.138.0.2: icmp_seq=3 ttl=64 time=0.313 ms 64 bytes from 10.138.0.2: icmp_seq=4 ttl=64 time=0.307 ms 64 bytes from 10.138.0.2: icmp_seq=5 ttl=64 time=0.298 ms 64 bytes from 10.138.0.2: icmp_seq=6 ttl=64 time=0.312 ms 64 bytes from 10.138.0.2: icmp_seq=7 ttl=64 time=0.438 ms 64 bytes from 10.138.0.2: icmp_seq=8 ttl=64 time=0.272 ms 64 bytes from 10.138.0.2: icmp_seq=9 ttl=64 time=0.262 ms 64 bytes from 10.138.0.2: icmp_seq=10 ttl=64 time=0.294 ms 64 bytes from 10.138.0.2: icmp_seq=11 ttl=64 time=0.269 ms 64 bytes from 10.138.0.2: icmp_seq=12 ttl=64 time=0.285 ms 64 bytes from 10.138.0.2: icmp_seq=13 ttl=64 time=0.313 ms ^C --- 10.138.0.2 ping statistics --- 13 packets transmitted, 13 received, 0% packet loss, time 12000ms rtt min/avg/max/mdev = 0.262/0.371/1.165/0.233 ms ``` **us-west1-a to us-west1-b (cross-zone)** ```shell PING 10.138.0.4 (10.138.0.4) 56(84) bytes of data. 64 bytes from 10.138.0.4: icmp_seq=1 ttl=64 time=1.88 ms 64 bytes from 10.138.0.4: icmp_seq=2 ttl=64 time=0.439 ms 64 bytes from 10.138.0.4: icmp_seq=3 ttl=64 time=0.447 ms 64 bytes from 10.138.0.4: icmp_seq=4 ttl=64 time=0.399 ms 64 bytes from 10.138.0.4: icmp_seq=5 ttl=64 time=0.520 ms 64 bytes from 10.138.0.4: icmp_seq=6 ttl=64 time=0.389 ms 64 bytes from 10.138.0.4: icmp_seq=7 ttl=64 time=0.425 ms 64 bytes from 10.138.0.4: icmp_seq=8 ttl=64 time=0.452 ms 64 bytes from 10.138.0.4: icmp_seq=9 ttl=64 time=0.409 ms 64 bytes from 10.138.0.4: icmp_seq=10 ttl=64 time=0.397 ms 64 bytes from 10.138.0.4: icmp_seq=11 ttl=64 time=0.393 ms 64 bytes from 10.138.0.4: icmp_seq=12 ttl=64 time=0.418 ms 64 bytes from 10.138.0.4: icmp_seq=13 ttl=64 time=0.355 ms ^C --- 10.138.0.4 ping statistics --- 13 packets transmitted, 13 received, 0% packet loss, time 12000ms rtt min/avg/max/mdev = 0.355/0.532/1.880/0.391 ms ``` **us-west1-a to us-central1-a (cross-region)** ```shell PING 10.128.0.2 (10.128.0.2) 56(84) bytes of data. 64 bytes from 10.128.0.2: icmp_seq=1 ttl=64 time=35.0 ms 64 bytes from 10.128.0.2: icmp_seq=2 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=3 ttl=64 time=34.1 ms 64 bytes from 10.128.0.2: icmp_seq=4 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=5 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=6 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=7 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=8 ttl=64 time=34.1 ms 64 bytes from 10.128.0.2: icmp_seq=9 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=10 ttl=64 time=34.1 ms 64 bytes from 10.128.0.2: icmp_seq=11 ttl=64 time=34.0 ms 64 bytes from 10.128.0.2: icmp_seq=12 ttl=64 time=34.1 ms 64 bytes from 10.128.0.2: icmp_seq=13 ttl=64 time=34.0 ms ^C --- 10.128.0.2 ping statistics --- 13 packets transmitted, 13 received, 0% packet loss, time 12002ms rtt min/avg/max/mdev = 34.027/34.158/35.080/0.270 ms ``` **us-west1-a to us-east1-b (cross-region)** ```shell PING 10.142.0.2 (10.142.0.2) 56(84) bytes of data. 64 bytes from 10.142.0.2: icmp_seq=1 ttl=64 time=67.2 ms 64 bytes from 10.142.0.2: icmp_seq=2 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=3 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=4 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=5 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=6 ttl=64 time=66.7 ms 64 bytes from 10.142.0.2: icmp_seq=7 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=8 ttl=64 time=66.7 ms 64 bytes from 10.142.0.2: icmp_seq=9 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=10 ttl=64 time=66.7 ms 64 bytes from 10.142.0.2: icmp_seq=11 ttl=64 time=66.7 ms 64 bytes from 10.142.0.2: icmp_seq=12 ttl=64 time=66.6 ms 64 bytes from 10.142.0.2: icmp_seq=13 ttl=64 time=66.6 ms ^C --- 10.142.0.2 ping statistics --- 13 packets transmitted, 13 received, 0% packet loss, time 12021ms rtt min/avg/max/mdev = 66.631/66.732/67.296/0.389 ms ```
