Amazon DocumentDB pricing is a reflection of its architecture: decoupled, scalable, and automated. While the pricing model involves multiple moving parts—compute instances, storage growth, and I/O operations—it offers the flexibility to match infrastructure costs directly to business value. By understanding the interplay between read replicas, I/O throughput, and the serverless option, organizations can deploy scalable document databases without succumbing to bill shock.
