Right-size Instances: Start with smaller instances and scale up as needed. Monitor Amazon CloudWatch metrics to see if your CPU or memory is underutilized.

The following factors affect the pricing of AWS DocumentDB: Right-size Instances: Start with smaller instances and scale
Leverage Reserved Instances: If you plan to use DocumentDB for a year or more, committing to a Reserved Instance (RI) can save you up to 65% compared to On-Demand pricing. It is not just a bill estimator; it
If you are migrating from open-source MongoDB to AWS DocumentDB (a purpose-built database for JSON data), you quickly realize one truth: Performance is elastic, but costs can be rigid. Unlike Amazon S3, where pricing is simple storage arithmetic, DocumentDB pricing is a multi-dimensional chess game involving instances, IOPS, storage, and backups.
Use I/O-Optimized Storage: If you have high-volume I/O workloads, AWS recently introduced a "DocumentDB I/O-Optimized" storage configuration. This offers predictable pricing by eliminating per-million I/O charges in exchange for a higher base storage price.
Most calculators ignore backups. The DocumentDB calculator includes a slider for "Backup Storage (GB)." AWS gives you 100% of your database size for free. If you have 500GB of database, you get 500GB of backup free. The slider is for incremental backup retention beyond that.
