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. The Atlas API uses the corresponding Atlas Region.
- Americas
- Asia Pacific
- Europe

Cluster Configuration Options¶
Each Atlas cluster tier 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 cluster tiers are available:
| Cluster Tiers | Default Storage | Default RAM |
|---|---|---|
| M2 | 2 GB | Shared |
| M5 | 5 GB | Shared |
| M10 | 10 GB | 1.7 GB |
| M20 | 20 GB | 3.8 GB |
| M30 | 40 GB | 7.5 GB |
| M40 | 80 GB | 15 GB |
| M40 Low-CPU (R40) 2 | 80 GB | 16 GB |

Cluster Tier & API Naming Conventions
For purposes of management with the Atlas API, cluster
tier names that are prepended with R instead of an M (R40
for example) run a low-CPU version of the cluster.
When creating or modifying a cluster with the API, be sure to specify
your desired cluster class by name with the
providerSettings.instanceSizeName attribute.
Workloads typically require less than 2TB of storage.
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 for a total of 60 IOPS per GB.
Example
The M30 cluster has a default storage size of 40 GB. This
results in a maximum read speed of 1,200 IOPS and a maximum write
speed of 1,200 IOPS. Increasing the storage size to 100 GB per
cluster increases the maximum read speed of 3,000 IOPS and a
maximum write speed of 3,000 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 effect 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.
