# MongoDB Pricing

MongoDB is a source-available cross-platform document-oriented database program for high-volume storage. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

There are two kinds of database cluster plans you can choose from: single node clusters and high availability clusters.

- **Single node clusters** begin at $15.00 per month for a single node cluster with 1 GiB of RAM. Single node clusters are not highly available. We recommend these clusters for preliminary development and testing.
- **High availability clusters** begin at $15.00 per month for a 2 GB RAM/1 vCPU primary node with at least two $15.00 per month standby nodes for automatic failover.

  We only support three node replica sets for high availability MongoDB clusters. For more information about MongoDB’s high availability cluster architecture, see [MongoDB’s official documentation](https://docs.mongodb.com/manual/replication/).

Traffic to and from [managed databases](https://docs.digitalocean.com/products/databases/index.html.md) does not count against your bandwidth billing transfer allowance.

## Plans for Cluster Nodes

All managed databases are deployed onto Droplets with either [shared or dedicated CPU](https://docs.digitalocean.com/products/droplets/concepts/choosing-a-plan/index.html.md#shared-vs-dedicated). For a list of the Droplet plans we offer for MongoDB, see the [Managed Databases pricing page](https://www.digitalocean.com/pricing/managed-databases#mongodb).
