Amazon DocumentDB instance pricing is more expensive than MongoDB Atlas, the fully managed MongoDB service. AWS DocumentDB starts at $200 per month for a single instance, with no free tier. Pricing is per instance-hour consumed, from the time an instance is launched until it is stopped or deleted. Partial instance hours are billed in one-second increments, but there is a 10-minute minimum charge following a billable status change such as creating, modifying, or deleting an instance.
Compare this with MongoDB Atlas, which has a perpetual free tier and starts at $9/mo for shared clusters, and around $60/mo for dedicated clusters.
The pricing comparison below is based on a default 3-node DocumentDB and MongoDB Atlas cluster, with backup storage equal to cluster storage. MongoDB Atlas is 8% to 19% less expensive.
