This document explains Cloud Bigtable pricing details. You can also use the Google Cloud Pricing Calculator to estimate the cost of using Bigtable.
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
Overview
When you use Bigtable, you are charged for the following:
- The type of Bigtable instance and the total number of nodes in your instance's clusters.
- The amount of storage that your tables use.
- The amount of network bandwidth that you use.
Storage and bandwidth usage are measured in binary gigabytes (GB), where 1 GB is 230 bytes. This unit of measurement is also known as a gibibyte (GiB).
Storage and bandwidth charges accrue daily. You can view unbilled usage at any time on the Google Cloud Console.
The following sections show the pricing for each component of Bigtable.
Nodes
Bigtable keeps track of how many nodes exist in your instance's clusters during each hour. You are charged each hour for the maximum number of nodes that exist during that hour, multiplied by the hourly rate. Bigtable bills a minimum of one hour for each node you provision.
Node charges are for provisioned resources, regardless of node usage. Charges apply even if your cluster is inactive.
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
Storage
Bigtable frequently measures the average amount of data in your Bigtable tables during a short time interval. For billing purposes, these measurements are combined into an average over a one-month period, and this average is multiplied by the monthly rate.
You are billed only for the storage used by Bigtable's internal representation on disk. For instances that contain multiple clusters, Bigtable keeps a separate copy of your data with every cluster, and you are charged for every copy of your data.
When you delete data from Bigtable, the data becomes inaccessible immediately; however, you are charged for storage of the data until Bigtable compacts the table. This process typically takes up to a week.
In addition, if you store multiple versions of a value in a column, or if you have set an expiration time for one of your table's column families, you can read the obsolete and expired values until Bigtable completes garbage collection for the table. You are also charged for the obsolete and expired values prior to garbage collection. This process typically takes up to a week.
Backups
You are billed only for the backup storage that you use, and a backup can never be larger than the original table. A backup is billed from the time it is created until the time it is deleted. Because of Bigtable's built-in storage optimizations, the cost of the backup might sometimes be less than the cost of a full physical copy of the table backup.
Network
Some types of network egress traffic are subject to bandwidth charges, as shown below.
| Ingress | Free |
| Egress to the same zone | Free |
| Egress between zones in the same region | Free |
| Cross-region network egress to the same continent (per GB) | $0.01 |
| Inter-continental egress | At Internet egress rate |
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
Internet egress rates
One-time, initial replication traffic
Each instance's clusters are located in zones, and each zone is located in a region. If you add a new cluster in a region, and none of the instance's existing clusters are in that region, you are charged a one-time cost for the initial data copy to the new cluster. For this initial copy, you are charged the network egress rate for the existing cluster that is geographically closest to the new cluster, multiplied by the amount of data in your tables. There is no charge for replication between clusters in a single region.
If you restore a new table from a backup, and the new table is in an instance that uses replication, you are charged standard network egress rates for the initial data copy to every cluster in the instance.
To illustrate the cost of adding a cluster to an instance, let's say your
instance has 9 TB of data, and its clusters are in
us-east1 (South Carolina) and europe-west1 (Belgium). If you add a new
cluster to the instance in the us-central1 (Iowa) region, your data is copied
to the new cluster from the existing cluster in us-east1, which is the closest
cluster in the instance. You are charged a rate of
$0.01 per GB, which is the network egress rate for
traffic between regions on the same continent. As a result, the initial
replication cost is $92.16:
9 TB * 1,024 GB/TB * $0.01 per GB = $92.16
In another example, let's say your instance has 9 TB of data, and its clusters
are in us-east1 (South Carolina) and us-west4(Las Vegas). If you add a new
cluster in europe-west2 (London), your data is copied to the new cluster from
the existing cluster in us-east1, which is the closest cluster in the
instance. You are charged a rate of $0.11 per
GB, which is the network cost for replication of 1 TB to 10 TB from the US to
Europe. In this example, the initial replication cost is
$1,013.76:
9 TB * 1,024 GB/TB * $0.11 per GB = $1,013.76
Ongoing replication traffic
When you write to a cluster, Bigtable automatically replicates the write from that cluster (the "source cluster") to all of the other clusters in the instance (the "destination clusters"). If a destination cluster is in a different region than the source cluster, you are charged to replicate the write to the destination cluster. The charge is equal to the network egress rate to the destination cluster, multiplied by the amount of data that you wrote to the source cluster. You incur a separate charge for every destination cluster that is in a different region than the source cluster.
For example, let's say you have a 3-cluster instance with clusters in
us-east1 (South Carolina), europe-west1 (Belgium), and
australia-southeast1 (Sydney). Over the course of a month, if your application
writes 5 TB of data to the cluster in us-east1, that 5 TB of data is
replicated from us-east1 to europe-west1 at the rate of
$0.11 per GB, which is the network cost for
replication of 1 TB to 10 TB from the US to Europe. The data is also replicated
from us-east1 to australia-southeast1 at the rate of
$0.18 per GB, which is the network cost for
replication of 1 TB to 10 TB from the US to Australia. In this example, the
30-day replication cost for the 5 TB of data originally written to the cluster
in us-east1 is $1,484.80:
(5 TB * 1,024 GB/TB * $0.11 per GB) + (5 TB * 1,024 GB/TB * $0.18 per GB) = $1,484.80
Pricing example: Single cluster with one node
Suppose you have a Bigtable instance that has one cluster. The cluster has one node, and your application server is in the same region as Bigtable. During a 30-day billing cycle, you use the following Bigtable resources:
- 1 instance in
us-central1(Iowa) with a single cluster that has 1 node throughout the month - Average of 50 GB of data stored on SSD drives in
us-central1 - No network ingress
- No network egress
Assuming that you are billed in USD, your Bigtable bill for the billing cycle is broken down as follows. Additional fees would apply for any other Google Cloud services used during the billing cycle, such as Compute Engine instances.
