Additional Services

Atlas Data Lake incurs costs for the amount of data scanned and returned by the service.

Atlas charges for the total number of bytes that Data Lake scans from your AWS S3 buckets, rounded up to the nearest megabyte. Atlas charges $5.00 per TB of scanned data, with a minimum of 10 MB or $0.00005 per query.

You can use partitioning strategies and compression in AWS S3 to reduce the amount of data scanned.

Atlas charges for the total number of bytes returned by Data Lake. This total is the sum of the following data transfers:

  • The number of bytes transferred between Data Lake service nodes
  • The number of bytes transferred from Data Lake to the client

Returned data is billed as outlined in the Data Transfer Fees section of the Atlas pricing page. The cost of data transfer depends on the Cloud Service Provider charges for same-region, region-to-region, or region-to-internet data transfer.

Atlas supports Encryption at Rest via customer KMS and LDAP User Authentication and Authorization in Atlas projects and clusters.

Excluding MongoDB Atlas Enterprise and MongoDB Atlas Platinum customers, Atlas charges a 45% uplift to the cost of each cluster with LDAP User Authentication and Authorization and/or Encryption at Rest via customer KMS enabled.

Configuring LDAP User Authentication and Authorization for a project enables the feature for all clusters in the project. Configuring Encryption at Rest via customer KMS for a project allows enabling/disabling the feature on per cluster basis.

MongoDB Atlas supports private endpoints on AWS using the AWS PrivateLink feature.

Atlas charges you based on your usage across these dimensions:

In addition to the costs Atlas charges you, AWS charges you for each VPC interface endpoint you create. To ensure cluster availability in the event of a widespread network outage, create VPC interface endpoints in at least two availability zones per region. AWS also charges you for the data volume each VPC interface endpoint processes.

Atlas charges hourly for each region to which you deploy a private endpoint. The hourly cost varies by region.

Additionally, Atlas charges you per hour based on the traffic that your private endpoint processes. The hourly cost varies based on the amount of traffic and the region to which your private endpoint is deployed.

Atlas private endpoint capacity units measure the dimensions on which the Atlas private endpoint processes your traffic. The dimensions measured are:

  • New connections or flows: Number of newly established connections or flows per second.
  • Active connections or flows: Peak concurrent connections or flows, sampled per minute.
  • Processed bytes: The number of bytes processed by the private endpoint in Gigabytes (GB).

For TCP traffic, an Atlas private endpoint capacity unit contains:

  • New connections or flows: 800 new TCP connections per second.
  • Active connections or flows: 100,000 active TCP connections (sampled per minute).
  • Processed bytes: 1 GB per hour.

For UDP traffic, an Atlas private endpoint capacity unit contains:

  • New connections or flows: 400 new UDP flows per second.
  • Active connections or flows: 50,000 active UDP flows (sampled per minute).
  • Processed bytes: 1 GB per hour.

For TLS traffic, an Atlas private endpoint capacity unit contains:

  • New connections or flows: 50 new TLS connections or flows per second.
  • Active connections or flows: 3,000 active TLS connections or flows (sampled per minute).
  • Processed bytes: 1 GB per hour.

Atlas charges you only for the dimension that has the highest usage during each hour across all traffic types.

Example

This provides a breakdown of costs for one hour of TLS network traffic to a private endpoint in the us-east-1 region:

Dimension
Amount
Atlas Private Endpoint Capacity Units Consumed
New connections or flows
25
.50
Active connections or flows
1500
.50
Processed bytes
2.5 GB
2.5

The Processed bytes dimension has the largest capacity unit consumption rate. For this hour, Atlas charges you the following for using Atlas private endpoint capacity units in the us-east-1 region:

Atlas rates for using the AWS PrivateLink feature vary by region:

Atlas supports database auditing. To learn more, see Set up Database Auditing.

Excluding MongoDB Atlas Enterprise and MongoDB Atlas Platinum customers, Atlas charges a 30% uplift in the hourly cost of all dedicated clusters for projects using Database Auditing.

MongoDB Realm applications may incur data transfer and compute costs for each application in a project. If you have MongoDB Realm applications in your organization, your invoice includes these costs as a line item.

Tip

Charts on Atlas is billed based on the volume of data transferred from the Charts web server to web browser clients. Each Charts instance comes with a free 1 GB of data transfers per month. Once the 1 GB of free data usage has been consumed, all subsequent GBs of data transfers are billed at a fixed rate.

If you have an upgraded support plan, the total support cost for the month is listed in the Summary section of your invoice. Support cost line items are listed in the Details section.
