Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
IOPS is the number of input/output operations that a storage system completes per second.
- How it is used
- Frames storage performance decisions for EBS volumes, EC2 instances, and EFS filesystems.
- How deep it goes
- Defines operation counting, workload effects, service limits, and monitoring, but does not derive storage-performance internals.
- Examples
- Uses EBS volume comparisons, small-file web workloads, shared home directories, and large-scale analytics as examples.
- What you can do after
- Evaluate storage workloads, select suitable EBS or EFS performance settings, and monitor EFS I/O limits with CloudWatch.

MongoDB 8.0 in Action, Third Edition
IOPS is the number of input and output operations that a storage system can perform per second.
- How it is used
- Supports Atlas storage-performance configuration by setting a cluster’s maximum IOPS rate.
- How deep it goes
- Explains provisioned-rate benefits and provider-specific change behavior, but does not develop an independent performance model.
- Examples
- Uses AWS-backed M30+ clusters, general-purpose SSD volumes, NVMe storage, and provider-specific storage changes.
- What you can do after
- Operate/configure Atlas storage by selecting provisioned IOPS and anticipating provider-specific capacity-change consequences.
