Cloud SQL Second Generation Pricing
Second Generation pricing is composed of the following charges:
Instance pricing for Second Generation is charged for every minute that the instance is running
(the activation policy is not set to
NEVER). The charge depends on the machine
type you choose for the instance.
Instance sizing is based on the corresponding Google Compute Engine machine type. However, not all values correspond exactly.
You can change the machine type for an existing instance. For help with editing an instance, see Editing Instances.
|Machine Type||Virtual CPUs||RAM (GB)||Maximum Storage Capacity||Price ($/hour)||Sustained Use Price ($/hour)|
Storage and Networking Pricing
The following storage and networking prices apply to Second Generation instances.
|Network||Ingress to Cloud SQL: Free
Note: Egress charges may apply on the source. For example, egress from Google Compute Engine is charged at the external IP addresses rate.
Egress from Cloud SQL: See Network Egress Pricing
Network Egress Pricing
When network traffic leaves a Google Cloud SQL instance, the charge applied depends on the destination of the traffic, and in some cases, whether a partner is involved.
Internet egress is network traffic leaving a Cloud SQL instance to a client that is not a Google product, such as using a local server to read data from Cloud SQL.
|Google Compute Engine instances||Within the same region: free
Between regions within North America: $0.01/GB
Between regions outside of North America: $0.12/GB
|Google Products (except Google Compute Engine)||
|Internet egress using Google Cloud Interconnect||$0.05/GB|
|Internet egress (not using Google Cloud Interconnect)||$0.19/GB|
Cloud SQL First Generation Pricing
For First Generation instances, Google offers two billing
plans: Packages and
Which plan you should select depends on how
your database will be used, but generally it is more economical to use the Package plan if your instance is used for more than
450 hours each month. If your instance is used sporadically, you can reduce costs by using the Per-use
plan and setting your activation policy to
ON DEMAND. Learn more.
When charging in local currency, Google will convert the prices listed into applicable local currency pursuant to the conversion rates published by leading financial institutions.
Packages Billing Plan
The following packages are available:
|Tier||RAM||Included Storage||Max Storage more info||Included I/O per Day||Charge per Day||Maximum Concurrent Connections|
You can change an instance's tier at any time, with just a few seconds of downtime.
At the end of a billing period, you are charged based on the number of days during which the database exists (measured at US Pacific Time). Storage for backups created using the scheduled backup service is not part of the package limits and is not charged. The number of I/O requests to storage made by your database instance depends on your queries, workload and data set. Cloud SQL will cache data in memory to serve your queries efficiently and to minimize the number of I/O requests. Use of storage or I/O over the included quota is charged at the Per-Use rate ($0.24 per GB per month for storage, $0.10 per Million of I/Os).
Storage is measured as the filespace used by the MySQL database. The size of all instances is limited to 250GB by default. Note that you only pay for the storage that you use, so you don’t need to reserve this storage in advance. If you require more storage, up to 500GB, contact email@example.com.
A newly created database uses about 270MB of space for system tables and InnoDB logs. If you create a per-use instance but do not use it, you are still charged for the storage cost. For an example pricing calculation covering this scenario, see Pricing examples.
Per-Use Billing Plan
The following resources are available, charged per minute of use:
|D0 Database Instance (0.125GB RAM)||$0.025 per hour|
|D1 Database Instance (0.5GB RAM)||$0.10 per hour|
|D2 Database Instance (1GB RAM)||$0.19 per hour|
|D4 Database Instance (2GB RAM)||$0.29 per hour|
|D8 Database Instance (4GB RAM)||$0.58 per hour|
|D16 Database Instance (8GB RAM)||$1.16 per hour|
|D32 Database Instance (16GB RAM)||$2.31 per hour|
|1GB Storage||$0.24 per month|
|I/O||$0.10 per Million|
- The maximum concurrent connections allowed for each tier is the same as for the Packages Billing Plan.
- Use of instances is charged per minute for periods of continuous use. (see the FAQ for more details).
- Storage is charged by the GB, and measured every
minute so your charges closely follow your usage. Storage charges are incurred whether the
instance is on or off.
- Storage for backups created using the scheduled backup service is not charged.
- A newly created database uses a small amount of space (270MB) for system tables and InnoDB logs. This is included in the charged storage. For an example pricing calculation covering this scenario, see Pricing examples.
- The default and maximum storage for an instance are the same as the Packages Billing Plan (see Storage Size).
- You can change an instance's tier at any time, with just a few seconds of downtime.
- The number of I/O requests to storage made by your database instance depends on your queries, workload and data set. Cloud SQL will cache data in memory to serve your queries efficiently and to minimize the number of I/O. I/Os are rounded up to the nearest million. Queries that do not access storage are not charged for I/Os.
|Internet Egress||$0.12 per GB|
Network use is charged for both packages and per-use billing plans. Only internet egress is charged, such as traffic to an admin or reporting tool or application hosted outside of the Google cloud. Network usage between Google App Engine applications, Google Compute Engine, or Google Cloud Storage and Cloud SQL are not charged.
Google Cloud SQL supports read replicas where the replica instances are other Cloud SQL instances or external MySQL instances.
- The only extra charge for replicating a Cloud SQL instance to another Cloud SQL instance is the cost of the replica instance.
- The only extra charge for replicating a Cloud SQL instance to external replicas is for the internet egress cost.
For more information about read replicas, see Requirements and Tips for Configuring Replication.
Instance IPv4 addresses
|Instance IPv4 Address||$0.01 per hour idle|
The use of an external IPv4 address for instances on the per-use billing plan is charged at $0.01 per hour for the time that the connection is idle. For example, if your per-use instance is idle, on average, 50% of the time, then an external IP address for the instance would cost $43.83 for one year.
Each Google Cloud SQL instance has an IPv6 address that you can also use to connect to the instance. The IPv6 address is independent of whether you assign and use an IPv4 address. Use of the instance IPv6 address is not charged. For more information, see Configuring access for IP connections.
First Generation Pricing examples
You can use the Google Cloud Platform Pricing Calculator to get pricing estimates for your Cloud SQL usage scenarios.
If your Cloud Platform Console project has Google Cloud SQL enabled but you have no Cloud SQL instances, then your project incurs no Google Cloud SQL charges. Your project starts to incur Google Cloud SQL charges when you create an instance. You are charged for the storage cost whether you use the instance or not. For example, if you create a D0 instance and never connect to it, the cost for the instance on the packages billing plan is $10.80 per month (for a 30 day month).
Per-use instance for trying out Cloud SQL
You can create a small Cloud SQL instance for less than $1 per month. For example, suppose your usage while trying out Cloud SQL has the following characteristics:
- Uses a D0 instance, storing less than 1GB of data.
- Uses the instance for 5 hours every week with a low number of I/O operations.
You can estimate a charge of less than $1 for one month for this scenario with the following selections in the Pricing Calculator:
- Usage equal to Part Time.
- Instance size equal to D0.
- Storage equal to 1 GB.
- I/O Operations over free quota per day equal to 0.
- Average hours per day each server is running equal to 5 hours.
- Average days per week each server is running equal to 1 day.
Per-use instance used only during business hours
Now consider a scenario where you move beyond just trying out Google Cloud SQL. For example, suppose your application has the following characteristics:
- Uses a D2 instance, storing less than 10 GB of data.
- Uses the instance exclusively during business hours (i.e., 160 hours per month), with a high number of I/O operations during those hours.
You can estimate a charge of less than $40 for one month for this scenario with the following selections in the Pricing Calculator:
- Usage equal to Part Time.
- Instance size equal to D2.
- Storage equal to 10 GB.
- I/O Operations over free quota per day equal to 100000.
- Average hours per day each server is running equal to 8 hour.
- Average days per week each server is running equal to 5 days.
