Pricing Calculator [updated]: Documentdb

: Compare Standard storage (lower base cost, pay-per-I/O) versus I/O-Optimized (higher base cost, I/O included).

While on-demand pricing is the default, Reserved Instances can provide up to 55% savings for 1- or 3-year commitments. 2. Storage Configurations

Would you like a sample that auto-calculates DocumentDB costs based on instance type, replicas, I/O, and storage? Or a comparison with DynamoDB pricing for similar workloads? documentdb pricing calculator

For the configuration, the calculator requires an estimate of your monthly I/O operations (read/write requests). AWS bills this at roughly $0.20 per 1 million requests. If your I/O costs exceed 25% of your total database spend, the I/O-Optimized tier typically becomes more cost-effective. 4. Backup Storage

| Strategy | Impact | |----------|--------| | | Save 40–60% on compute (1-yr or 3-yr commitment) | | Right-size instances | Monitor CPU & RAM – don't over-provision | | Reduce replicas | For dev/test, use 0 replicas | | Optimize I/O | Use projection ( field:1 ) to avoid large document reads. Batch writes. | | Enable TTL indexes | Automatically delete old data to reduce storage + I/O | | Backup pruning | Delete old manual snapshots | | Use same AZ | Avoid cross-AZ data transfer costs (for replicas) | | Stop idle clusters | Non-production clusters can be stopped (no compute charge, but storage remains) | : Compare Standard storage (lower base cost, pay-per-I/O)

Options range from the cost-effective db.t3.medium (starting at roughly $0.078/hr in some regions) to large, memory-optimized db.r8g Graviton instances for heavy workloads.

DocumentDB provides equal to the total storage of your cluster (for automated backups). Additional backup storage (or manual snapshots beyond retention) costs: Storage Configurations Would you like a sample that
