Synopsis¶
Atlas supports deploying clusters onto Google Cloud Platform (GCP). This page provides reference material related to Atlas cluster deployments on GCP.
Atlas supports the following GCP regions:

Instance Configuration Options¶
Each Atlas instance size comes with a default set of resources. Atlas provides the following resource configuration options:
- Custom Storage Size
The size of the server root volume. Atlas clusters deployed onto GCP use SSD persistent storage [1].
The following instance sizes are available:
Instance size Maximum disk storage M0512MB M22GB M55GB M1080GB M20180GB M30370GB M40750GB M503TB M604TB M804TB M2004TB M3004TB Workloads typically require less than
2TB.
Atlas configures the following resources automatically and does not allow user modification:
- Storage Speed
The input/output operations per second (IOPS) [1] the system can perform. This value is fixed at 30 IOPS per GB for reads and 30 IOPS per GB for writes.
Example
The
M30instance size has a default storage size of 40GB per instance and a max storage speed of 1200 max IOPS. Increasing the storage size to 100GB per instance increases the max storage speed to( 30 IOPS / GB * 100 GB)or 3000 IOPS.- Encrypted Storage Volumes
- GCP storage volumes are always encrypted.
GCP Zones¶
Each GCP region includes a set number of independent zones. Each zone has power, cooling, networking, and control planes that are isolated from other zones. For regions that have at least three zones (3Z), Atlas deploys clusters across three zones. For regions that only have two zones (2Z), Atlas deploys clusters across two zones.
The Atlas Add New Cluster form marks regions that support 3Z clusters as Recommended, as they provide higher availability.
The number of zones in a region has no affect on the number of MongoDB nodes Atlas can deploy. MongoDB Atlas clusters are always made of replica sets with a minimum of three MongoDB nodes.
For general information on GCP regions and zones, see the Google documentation on regions and zones
Regions with at Least Three Zones¶
If the selected GCP region has at least three zones, Atlas clusters are split across three zones. For example, a three node replica set cluster would have one node deployed onto each zone.
3Z clusters have higher availability compared to 2Z clusters. However, not all regions support 3Z clusters.
