Pricing & Usage

RRSMB software is billed on AWS Marketplace as hourly consumption. You pay only for Windows SMB shares connected to EFS, plus mounted EFS storage — not per cluster node. Standard AWS EFS charges are billed separately by AWS.

🗂️
$0.10
per Windows SMB share connected to EFS / hour

Billed as ShareHours — one unit per share on EFS each hour. Delete a share in the Admin UI to stop accruing for that share on the next hourly billing tick.

Amazon EFS
$0.00007
per mounted EFS GB-hour

Billed as ManagedStorageGBHours. Standard AWS EFS storage and access charges apply separately.

Pause & resume with zero software charges

Scale the Auto Scaling Group to 0 (or terminate the rrsmb nodes) to pause the appliance. While offline, RRSMB records SKIPPED_OFFLINE billing rows with quantity zero — no ShareHours or ManagedStorageGBHours accrue during paused periods.

Ideal for weekends, holidays, dev/test environments, or any time you do not need SMB service running. Resume by scaling the ASG back up; billing resumes only while the cluster is running.

This is separate from AWS EFS storage charges, which continue for data at rest in EFS regardless of appliance state — the same as any EFS workload.

Node count

Dual-AZ production clusters are configurable from 2 to 8 nodes (9-16 is Experimental). The Eval Kit is a fixed 2-node single-AZ deployment for evaluation and non-HA use only. Marketplace fees above apply per connected share and mounted storage — not per node.

The TCO point that holds: Elastic Throughput

Morning login storms need a burst of backend throughput. FSx for Windows bills a provisioned throughput tier 24x7. Roadrunner SMB on Amazon EFS Elastic Throughput follows that storm and the quiet hours after it. That is the durable savings mechanism - not a 40-60% claim across every configuration.

Illustrative week: 24x7 provisioned FSx peak stays flat; Roadrunner SMB on EFS Elastic Throughput tracks morning login storms
Illustrative week. Actual AWS charges vary by workload, Region, and pricing. See the architecture comparison.

Elastic storage and Infrequent Access

Amazon EFS Lifecycle Management can move eligible files into Infrequent Access automatically while users keep the same SMB shares. That is elastic storage with automatic IA for idle data - an Amazon EFS capability in your account. Configuration options are too wide for a single comparative savings claim. See Product & Architecture for performance, stability, flexibility, and active-active scale-out.

Stop permanently

Delete the CloudFormation stack when finished evaluating or decommissioning. Software charges stop; your files remain in Amazon EFS in your account. Unsubscribe from the Marketplace listing if you no longer need the product.

Charges appear on your AWS bill under AWS Marketplace as hourly consumption.

Low-risk to try

Hourly metered billing on AWS Marketplace — run only the shares and storage you need. Scale to 0 to pause with zero software charges, or delete the stack when you are done.
