Atlas supports deploying clusters and serverless instances onto Google Cloud Platform (GCP).

Atlas supports the following Google Cloud regions. While all of the following regions support dedicated clusters (M10+), some regions don't support free and shared clusters (M0/M2/M5) or serverless instances. The Atlas API uses the corresponding Atlas Region.

Cluster Configuration Options

Each Atlas cluster tier comes with a default set of resources. Atlas provides the following resource configuration options.

Custom Storage Size

Storage size reflects the size of the server root volume. Atlas clusters deployed onto Google Cloud use SSD persistent storage [1].

Note

RAM Availability

The actual amount of RAM available to each cluster tier might be slightly less than the stated amount, due to memory that the kernel reserves.

The following cluster tiers are available:

Note

Cluster Tier & API Naming Conventions

For purposes of management with the Atlas Administration 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.

Important

Multi-Cloud Low-CPU clusters

Low-CPU cluster tiers (R40, R50, R60, etc) are available in multi-cloud cluster configurations as long as the cluster tier is available for all the regions that the cluster uses.

Workloads typically require less than 2TB of storage.

Atlas configures the following resources automatically and does not allow user modification:

  • Storage Speed

  • Encrypted Storage Volumes

Storage Speed

Storage speed is the number of input/output operations per second (IOPS) [1] that the system performs. This value is fixed at:

  • 30 IOPS per GB for reads

  • 30 IOPS per GB for writes, for a total of 60 IOPS per GB

For example, an M30 cluster with 40 GB of default storage has a maximum read speed of 1,200 IOPS and a maximum write speed of 1,200 IOPS. If you increase the storage size to 100 GB per cluster, this increases the maximum read speed by 3,000 IOPS and a maximum write speed by 3,000 IOPS.

IOPS smaller than 16B are counted as one IO. IOPS larger than 16KB are counted as multiple IOs. For example, a 128KB IO counts as eight IOs.

Encrypted Storage Volumes

Google Cloud storage volumes are always encrypted.

GCP Zones

Each Google Cloud 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 multiple zones, such as 2Z (for two zones) or 3Z (for 3 zones), Atlas deploys clusters across these zones.

The Atlas Add New Cluster form marks regions that support 3Z clusters as Recommended, as they provide higher availability.

To learn more, see regions and zones in the Google documentation.

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.

Regions with at Least Three Zones

If the selected Google Cloud 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.

[1](1, 2, 3) To learn more, see Storage Options in the Google documentation.

Dedicated Search Nodes

Supported Regions

Atlas supports deploying separate Search Nodes for M10 and higher clusters in any Google Cloud region.

Available Search Tiers

Atlas provides different search tiers for Search Nodes deployed on Google Cloud. These search tiers are available for each class of hardware, low-CPU or high-CPU:

Note

Most Search Nodes use NVMe-attached Local SSD disks for storage. Search nodes with the following search tiers use SCSI-attached SSD Persistent Disks [1]:

  • S20 High-CPU Instances

  • S30 Low-CPU Instances

Integrations

Along with global region support, the following product integrations enable applications running on Google Cloud, such as Google Compute Engine, Google Cloud Functions, Google Cloud Run, and Google App Engine, to use Atlas instances easily and securely.
