Operation charges apply when you perform operations within Cloud Storage. An operation is an action that makes changes to or requests information about resources such as buckets and objects in Cloud Storage.

Operations are divided into three categories: Class A, Class B, and free. See below for a breakdown of which operations fall into each class.

For buckets located in a single region:

For buckets located in a dual-region or multi-region:

Operations that fall into each class

The following table lists the operations that fall into each class for the JSON API, XML API, and gRPC. Keep in mind the following:

• Except as noted in the footnotes, each request is considered one operation, regardless of the content sent or received as part of the request.
• Tools such as the Google API console, the Google Cloud CLI, and the Cloud Storage client libraries might use two or more operations to perform a task. For example, when you click on a bucket name in the Google Cloud console, the system performs an operation to get the list of objects in the bucket and a separate operation to get the metadata for the bucket.
• The Google API console uses the JSON API to make requests. Other tools might use either or both the JSON API and XML API. Consult the tool's reference documentation for information about the underlying API that it uses.

In Hierarchical Namespace buckets, iterative (recursive) folder operations are billed as class A for each child operation. There are two types of iterative folder operations:

1. Operations that create missing parent folders automatically. Each parent folder created is considered a child operation. This includes the following operations (and their equivalents in the XML API, if applicable):
2. storage.objects.insert
3. storage.objects.compose
4. storage.objects.copy
5. storage.objects.move
6. storage.objects.rewrite
7. storage.objects.restore
8. storage.managedFolders.insert
9. storage.folders.insert (when recursive is set to true)
10. Complete a multipart upload (this is a POST operation in the XML API)
11. The rename folder operation. Each child folder under the top-level folder being renamed is considered a child operation.

¹A rewrite or resumable upload of a single object performed using the JSON API or gRPC is billed as a single Class A operation, even though these actions can require multiple requests to complete.

²Applies specifically to Object Change Notifications. For Pub/Sub notifications, see Pub/Sub pricing.

³Tag operations are not eligible for the Cloud Storage Always Free program.

Note: Generally, you are not charged for operations that return 307, 4xx, or 5xx responses. The exception is 404 responses returned by buckets with Website Configuration enabled and the NotFoundPage property set to a public object in that bucket.

A retrieval fee applies when you read, copy, move, or rewrite object data or metadata that is stored using Nearline storage, Coldline storage, or Archive storage. This cost is in addition to any operations charges and network charges associated with reading the data.

The following table shows the retrieval rates for each storage class:

Retrieval fees do not apply when an object exists in a bucket that has Autoclass enabled.

Retrieval fees do not apply when restoring soft-deleted objects.

Retrieval fees do not apply for data read from Anywhere Cache.

Inter-region replication is billed on a per-GB basis for all data written to buckets located in a dual-region or multi-region location. Writes include puts, rewrites, copies, and any other actions that create new objects.

Inter-region replication fees do not apply when restoring soft-deleted objects.

The following additional charges are associated with buckets that use the Autoclass feature:

Autoclass management fee: Buckets that have Autoclass enabled incur a fee of $0.0025 for every 1000 objects stored for 30 days within them.

• Objects smaller than 128 kibibytes are not managed by Autoclass and are thus not counted when determining the fee.
• The fee is prorated to the millisecond for each object that isn't stored for the 30-day period.
• The fee is also prorated to the millisecond when disabling Autoclass.
• Soft-deleted objects do not incur this fee.

Autoclass enablement charge: Buckets that enable Autoclass have a one-time charge for configuring existing objects to use Autoclass. This charge applies even if you immediately disable Autoclass and includes the following, as applicable:

• Early delete charges for objects that haven't met their minimum storage duration
• Retrieval fees for objects not currently in Standard storage
• A Class A operation charge for each object in the bucket, in order to transition them to Autoclass pricing and Standard storage
• Objects that are smaller than 128 kibibytes, and already stored in Standard storage at the time Autoclass is enabled are excluded from this operation charge

The Autoclass enablement charge does not apply to soft-deleted objects, which retain their existing storage classes and are billed as such until the end of their soft delete retention duration.

Outbound data transfer represents data sent from Cloud Storage in HTTP responses. Data or metadata read from a Cloud Storage bucket are examples of data transfer.

Inbound data transfer represents data sent to Cloud Storage in HTTP requests. Data or metadata written to a Cloud Storage bucket are examples of inbound data transfer.

Network usage charges apply for data transfer and are divided into the following cases:

• Data transfer within Google Cloud, when data transfer is to other Cloud Storage buckets or to Google Cloud services.
• Specialty network services, when data transfer uses certain Google Cloud network products.
• General data transfer, when data transfer is out of Google Cloud or between continents.

Data transfer within Google Cloud applies when you move or copy data from one Cloud Storage bucket to another or when another Google Cloud service accesses data in your Cloud Storage bucket.

The following cases of data transfer from a Cloud Storage bucket to within Google Cloud are free:

You can use Anywhere Cache to avoid data transfer fees associated with multi-region buckets on reads, once data is ingested into the cache.

For all other data transfer from your Cloud Storage buckets to within Google Cloud, pricing is determined by the bucket's location and the destination location, as defined in the following matrix:

If you have chosen to use certain Google Cloud network products, data transfer pricing is based on their pricing tables:

• For Cloud CDN, Cloud Storage data transfer charges are waived, but cache fill charges may apply. For more information, see Cloud CDN pricing.
• For Media CDN, Cloud Storage data transfer charges are waived. For more information, contact sales.
• For CDN Interconnect, see CDN Interconnect pricing.
• For Cloud Interconnect, see Cloud Interconnect pricing. For more information, see the Cloud Interconnect overview.
• For Direct Peering, see Direct Peering pricing.

General network usage applies for any data read from your Cloud Storage bucket that does not fall into one of the above categories or the Always Free usage limits. For example, general network usage applies when data moves from a Cloud Storage bucket to the Internet. You can view your current usage in the billing details for your project.

AI-powered Storage Intelligence provides you with insights to help you manage and optimize storage at scale. Generate storage insights datasets specific to your environment by querying object metadata at scale. Use bucket relocation to minimize application downtime by automatically moving entire buckets while preserving their bucket names. Perform batch operations at scale using managed jobs on millions of objects.

Storage Intelligence charges apply when configuring and using various capabilities as follows:

Standard Tier

When configured for Standard tier the Storage Intelligence Standard Object Management Fee ($2.5 per million objects per month) applies to all objects within the specified Organization / Folder / Project. Unless filters are specified all buckets are included even as new ones are added. Any buckets that are removed from Standard Tier within 30 days of inclusion incur Storage Intelligence Early Termination Fee for the remaining duration. Charges are amortized daily and only apply to objects that exist more than 24 hours.

Insights Datasets

These can be configured for the same Organization / Folder / Project as the Storage Intelligence tier. When configured, daily snapshots are delivered for all the buckets/objects that have been enabled with Standard tier. Any number of Datasets can be configured for the same buckets and the Standard tier fee is only applied once. BigQuery storage fees does apply for every instance for Datasets. Typically 1 TB of Cloud Storage data generates 300 MB of metadata daily however this can vary based on custom metadata stored within objects. Customers can configure the duration of snapshot retention. If Storage Intelligence is disabled for a project then new snapshots will not be delivered however the existing BigQuery data will not be deleted and will continue to incur storage charges. Customers can delete the Datasets configuration at any time to remove their data from BigQuery.

Storage batch operations

• Storage Batch Operations is exclusively available to Storage Intelligence customers. There are no additional charges for using Batch Operations beyond the subscription fee of Storage Intelligence.
• Operations charges: All operations performed by Batch Operations incur operations charges based on the storage class of the object being acted on.
• Deletions performed by Batch Operations do not incur any charges.
• All transformations performed by Batch Operations, except object deletions, incur a Class B operation charge.
• All transformations performed by Batch Operations, except object deletions, incur a Class A operations charge. This operation charge does not apply if the object is already in the desired end state.

Bucket relocation

When using bucket relocation, a $0.04 per GB charge applies for all data successfully moved to the destination. In addition, the following charges apply:

• Storage Intelligence: Bucket relocation is a premium feature offered as a part of Storage Intelligence. Storage Intelligence must be enabled on the source bucket to use bucket relocation.
• Data transfer charges: You pay inter-region data transfer charges for moving the data from the source to the destination region. Data transfer is charged per GB of data moved.
• Operation charges: You pay one Class A operation per object moved. Additional Class A operations are charged to resynchronize object metadata for objects whose metadata have been updated since the move started. This can mean up to N additional Class A operations for an object updated N times after the move started.
• Data storage charges: You pay for data storage charges in both the source and destination locations while bucket relocation processes the move, temporarily increasing your storage charges. Once the move has completed, you only pay for data storage based on the new, destination location.
• Data replication charges: If the destination of the move is a multi-region or dual-region bucket, inter-region replication charges apply since the destination data must be replicated to a remote region.
• Data retrieval charges: Retrieval fees are not assessed as part of a bucket relocation.
• Early deletion charges: You are not billed early deletion charges for the data cleanup in the source bucket after the move.

Pricing example for Storage Intelligence

If you have 1000 objects in 1000 buckets that are distributed over 10 projects and you enable Storage Intelligence for all 10 projects, or at Organization level that includes these 10 projects, then you will be charged a monthly Storage Intelligence Standard Object Management Fee of $2.5 for the 1 million objects (1000 objects x 1000 buckets). Charges are applied to the same project where buckets are present.

These charges are applied daily, with $/million objects rate amortized over 30 days. If you have less than a million objects then the charges are amortized so you only pay for the set of objects that are under management for the duration of their existence (over 24 hours).

A 30-day early termination fee which applies when a bucket is removed from a subscription within 30 days of enrollment. Any bucket deletions do not incur this 30-day early termination fee. If you disable Storage Intelligence after 24 days of enablement (6 days remaining) then for example a total of $0.5 Early Termination Fee will be applied on the 25th day for the 1000 buckets that were removed.

Inventory Reports are subject to pricing, where every one million objects contained in an inventory report is charged at the pricing below, dependent upon storage location. For more information about storage locations, see Bucket locations.

Supported locations

Anywhere Cache pricing is based on the following components:

• Cache storage: the amount of data stored in cache
• Cache ingest: the amount of data written into the cache
• Cache data transfer out: the amount of data read from the cache
• Cache data transfer out operations: the amount of read requests served from the cache
• Cache management operations: the amount of bucket-level cache management requests (normally not significant on bills)

The following pricing applies to any bucket where Anywhere Cache is enabled. Anywhere Cache pricing is supplemental to the overall service pricing. Unless explicitly stated, the Cloud Storage service prices provided elsewhere in this document continue to apply in addition to Anywhere Cache prices.

When reading data that is not already cached in the same zone where the data is being read, all normal Cloud Storage prices apply for the request (for example: Class B operations and multi-region data transfer out charges). In addition, the cache ingest charge applies to load the data being read into the cache. Once data is in the cache, cache storage charges apply until it is evicted from the cache.

When the data being read in a particular zone is already cached in that zone’s cache, cache operations charges apply for requests instead of the normal higher priced Class B operations. Cache data transfer out charges are also assessed based on the volume of data read.

Bucket-level cache configuration and management requests incur normal Class A or Class B operations, per the table in the Operation section.

Please see the Anywhere Cache documentation for more detailed information on how you can control costs using Anywhere Cache.

Cache Storage Charges

Data cached by Anywhere Cache incur a per-GB, per-hour storage fee, with charges pro-rated to the second for each byte of data. Prices are set by region and are listed under the Anywhere Cache column under Data Storage above.
