Bucket Locations

This page explains the concept of bucket location and the different locations where you can create buckets. To learn how to set the location for your bucket, see Creating Storage Buckets. To learn how to view or change a bucket's location, see Managing Buckets.

Overview of bucket locations

In Google Cloud Storage, you create a bucket to store your data. A bucket has three properties that you specify when you create it: a globally unique name, a default storage class, and a location where the bucket and its contents are stored. For example, if you specify the location eu (European Union) when you create bucket A, then bucket A and any objects in bucket A are stored on servers in the European Union. When you specify a location, Google will keep it there in accordance with our Service Specific Terms.

Typically, a good location for your bucket balances latency, availability, and bandwidth costs for applications and users of the bucket data. For more information, see Choosing the best location for your data.

For a world map showing the locations of Google Cloud Platform services, see the Cloud Locations page.

Types of locations

There are two types of locations where you can create buckets: multi-regional locations and regional locations.

Note that this terminology is distinct from the storage classes Multi-Regional Storage and Regional Storage; however, these storage classes must be created in a location of equivalent type. For example, if you want to create a bucket that has the default storage class Regional Storage, such a bucket must be created in a regional location, such as us-east1. For more information about storage classes, see the Storage Classes page.

Multi-regional locations

A multi-regional location is a general geographical area, such as the United States. Multi-regional locations contain multiple regional locations. The following multi-regional locations are available:

  • asia — Asia Pacific
  • eu — European Union
  • us — United States

Multi-Regional Storage data is stored in a bucket created in a multi-regional location. In addition, Multi-Regional Storage data is geo-redundant, which means the data is redundant across two or more datacenters separated by at least 100 miles within the selected multi-regional location.

Nearline Storage or Coldline Storage data can be stored in a bucket created in either a multi-regional location or a regional locations. When Nearline Storage or Coldline Storage data is stored in a multi-regional location, it is placed within one of the regions that make up the multi-regional location.

You cannot store Regional Storage data in a bucket created in a multi-regional location.

Regional location

A regional location is a specific geographic place, such as Council Bluffs, IA. The following regional locations are available:

  • asia-east1 — Taiwan
  • asia-northeast1 — Tokyo
  • asia-southeast1 — Singapore
  • europe-west1 — Belgium
  • us-central1 — Iowa
  • us-east1 — South Carolina
  • us-west1 — Oregon

All regional locations are separated from other regional locations by at least 100 miles.

Regional Storage data is stored in a bucket created in a regional location. Such data is placed in datacenters located in the specified region.

Nearline Storage or Coldline Storage data can be stored in a bucket created in either a regional location or a multi-regional location. When Nearline Storage or Coldline Storage data is stored in a regional location, it is placed in one of the datacenters located in the specified region. When stored in a multi-regional location, Nearline Storage and Coldline Storage data are placed in one of the regions within the specified multi-region.

You cannot store Multi-Regional Storage data in a bucket created in a regional location.

Zone

An isolated location within a region where you can create Google Compute Engine instances. A zone within a region is independent of other zones in the same region. All Compute Engine instances created within zones in the same region have similar performance accessing Google Cloud Storage.

You can't specify a bucket location as a zone.

Choosing the best location for your data

Multi-regional location

Data stored in a multi-regional location whose storage class is Multi-Regional Storage is redundant across multiple regions. This provides maximum accessibility of your data, even in the event of large-scale disruptions, such as natural disasters. Multi-Regional Storage storage is useful for:

Serving multimedia worldwide

For serving web or mobile content, particularly multimedia, across a continent or the world, storing your data in a multi-regional location maximizes performance and accessibility for end-users.

Geo-redundancy

If your application cannot tolerate the unavailability of data in a single region, use a multi-regional location with the Multi-Regional Storage class.

Data stored in a multi-regional location whose storage class is Nearline Storage or Coldline Storage is stored somewhere within the geographic area covered by the specified multi-regional location. This allows Google to optimally balance availability, performance, and resource efficiency on your behalf.

If you don't have a specific application use or regional need for your data, then store your Nearline Storage or Coldline Storage data in a multi-regional location that is convenient or includes the majority of the data client.

Regional location

Regional locations allow you to store your data in a specific region. You can use a bucket placed in a regional location when you need to optimize latency, availability, and network bandwidth costs for an application in the same region. Data stored in regional location can still be read globally, but if your bucket data is going to be used primarily by clients outside the region, use a multi-regional location instead.

All Cloud Storage and Google Cloud Platform resources in a region share the same network fabric, which reduces the latency and improves the bandwidth of other regional resources accessing specific-region bucket data. Scenarios for storing data in a regional location include:

Data Processing and Analysis

You can place your Regional Storage data within the same region as your Compute Engine instances that you use for data analysis and processing. Doing so gives you better performance for data-intensive computations, as opposed to storing your data in a multi-regional location. In addition, storing your data in a regional location in this scenario can reduce network charges.

If your application isn't sensitive to data availability, for example, batch processing pipelines or data backups, then you can use the Nearline Storage class for your bucket.

Disaster Recovery or Archiving

With a bucket configured for Coldline Storage, you can prepare for a disaster recovery event by placing your data in a region where you would need to recover it, decreasing recovery time and ensuring low-latency access. You can use several buckets placed in different regions together as part of a coordinated, global disaster recovery infrastructure. For examples, see Disaster Recovery Cookbook.

For an archiving application, you can create a Nearline Storage or Coldline Storage bucket that is located geographically close to the data to be archived, thereby reducing network bandwidth charges.
