Cloud Bigtable pricing

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.

When you use Bigtable, you are charged for the following:

  1. The type of Bigtable instance and the total number of nodes in your instance's clusters.
  2. The amount of storage that your tables use.
  3. 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 for the physical storage used by Bigtable's internal representation on disk. Bigtable compresses your data, reducing the amount of storage it occupies. In addition, Bigtable regularly goes through a process called compaction to further reduce your storage cost. Compaction typically happens within a week of data being written or deleted.

Deleted data becomes inaccessible immediately; however, you are charged for storage of the data until Bigtable compacts the table. In addition, if you store multiple versions of a value in a column and set an expiration time for older versions or limit the number of versions, you are also charged to store the expired values prior to garbage collection, which follows a similar cadence to compaction.

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.

If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

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.

If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

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

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 rate for replication to 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 the standard network rate for replication 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, the rate for network traffic within the US for replication. 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 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 rate for replication 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 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 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.
