Pricing

A Databases for PostgreSQL Standard plan deploys as one highly available PostgreSQL cluster with two data members, with your data replicated on both members. The Standard plan is priced based on the total amount of disk storage, RAM, dedicated cores, and backup storage that is allocated to deployments, prorated hourly. Databases for PostgreSQL deployments have a minimum of 5 GB of disk and 1 GB of RAM per data member.

Using the Pricing Calculator

Templates are provided for ease of use and provide balanced resource allocations appropriate for general-purpose workloads. The Custom tab can be used to configure Disk, RAM, and vCPU, as wanted.

For pricing estimation, use the Add to Estimate button on the Databases for PostgreSQL catalog page. Input your total consumption across two data members into the calculator. This is roughly double the size of your data because your data is replicated to both members. For example, 5 GB of disk and 1 GB of RAM across two data members would be priced at 10 GB of disk and 2 GB of RAM respectively.

Backups Pricing

You receive your total disk space purchased, per database, in free backup storage. For example, in a given month, if you have a Databases for PostgreSQL deployment that has 20 GB of disk per member, and has three data members, you receive 60 GB of backup storage free for that month. If your backup storage utilization is greater than 60 GB for the month (in this scenario), you are charged an overage of $0.03/month per gigabyte.

By default, Cloud Databases provides a daily backup that is stored for 30 days. These backups, and any on-demand backups you make, all count toward the above allocation.

In the above example, if your database contains 2 GB of data and you have not taken any on-demand backups, then your total backup size is 2 GB x 30 = 60 GB. Your backup costs are nil.

If your database contains 15 GB of data and you have not taken any on-demand backups, then your total backup size is 15 GB x 30 = 450 GB. In this scenario, your backup costs are (450 GB - 60 GB) * 0.03 = $11.7 per month.

Most deployments will not ever go over the allotted credit.

Dedicated Cores Pricing

You have the option of selecting the CPU allocation for your deployment. With dedicated cores, your resource group is given a single-tenant host with a guaranteed minimum reserve of cpu shares. Your deployments are then allocated the number of CPUs you specify. The cost of dedicated cores is $30 per core per month, and each member gets the selected number of cores. For example, if you provision a deployment with three dedicated cores per member that is a total of six cores and billed at $180 per month.

Dedicated cores are an optional feature. The default Shared CPU setting provisions your deployment on hosts with shared compute resources and incurs no additional charge.

Scaling per Member

Databases for PostgreSQL deployments have minimum and maximum allocation for disk and RAM as shown. Scaling deployments through the API/CLI provides more granularity and also allows a user to scale a database instance up to 4 TB of disk per member.

Table 1. Per Member Scaling Limits
Resource Minimum Maximum Scaling Granularity (API/CLI)
Disk 5 GB per member 4 TB per member 1024 MB per member
RAM 1 GB per member 112 GB per member 128 MB per member
CPU (if enabled) 3 CPUs per member 28 CPUs per member 1 CPU per member
