Amazon Documentdb Price [patched] -

Date: April 14, 2026 Subject: Cost structure, components, and optimization strategies for Amazon DocumentDB 1. Executive Summary Amazon DocumentDB is a fully managed, scalable NoSQL database service designed for JSON workloads. Unlike traditional licensing models, DocumentDB pricing is consumption-based, combining compute (instance hours), storage (GB-month), and I/O requests. There are no upfront license fees , but costs can scale rapidly with high I/O workloads. The most cost-effective option for production is 1-year or 3-year Reserved Instances , which can reduce compute costs by up to 60% compared to On-Demand. 2. Core Pricing Components | Component | Billing Unit | Key Details | |-----------|--------------|--------------| | Compute (Instances) | Per instance hour | Cost varies by instance class, region, and deployment type (Single-AZ vs Multi-AZ). | | Storage | GB per month | Automatic scaling from 10 GB to 64 TB. No pre-provisioning needed. | | I/O Requests | Per 1 million requests | Charged for both read and write I/Os. Often the largest variable cost. | | Backup Storage | GB per month | Backup storage up to 100% of provisioned database storage is free. Additional backup storage incurs charges. | | Data Transfer | GB transferred | Outbound internet data transfer is charged (inbound is free). | Note: There are no charges for cloning a database cluster within the same AWS region. 3.
