Roadrunner SMB

Roadrunner SMB™ delivers Elastic SMB for Amazon EFS - native Windows file services on the elastic, AWS-native storage you already run. It deploys as a configurable 1-to-4 node SMB3 gateway that gives Windows users, applications, and virtual desktops domain-joined file shares backed by EFS, without building or maintaining your own Samba infrastructure.

It integrates with Active Directory, supports Kerberos authentication, enforces Windows ACLs, and preserves native permission inheritance, so users reach shared files over familiar UNC paths with standard Windows clients. Typical workloads include VDI and Windows DaaS desktops (Amazon WorkSpaces, Citrix, Windows 365), departmental shares, home directories, user profiles, and Windows file migrations to AWS.

An Elastic SMB™ metadata acceleration layer reduces metadata latency for bursty, small-file Windows and VDI workloads using an L1 RAM cache with DynamoDB-backed distributed state, addressing the metadata-heavy access patterns common to profile, desktop, and departmental shares.

Deployment is via AWS CloudFormation into your existing VPC, provisioning the required resources: Network Load Balancer, ECS cluster, IAM roles, security groups, and EFS-backed share integration. A browser-based Admin UI handles first-time setup, Active Directory configuration, share management, cluster health, and software updates.

Node sizing is configurable from 1 to 4. A single node is intended for evaluation and low-cost non-HA use; multi-node deployments are designed for high-availability production and can span Availability Zones. Node-target changes are made in the Admin UI and applied through the Roadrunner SMB CloudFormation stack as the system of record. Automatic software updates are enabled by default, delivering approved fixes and improvements through the AWS Marketplace container image release channel - no manual stack edits.

Roadrunner SMB is built for IT teams, MSPs, and AWS customers modernizing Windows file services, replacing self-managed Windows or Samba file servers, or moving Windows file workloads to AWS while preserving native SMB access and Active Directory security semantics.

Key capabilities:

• SMB3 file sharing backed by Amazon EFS
• Active Directory domain join and Kerberos authentication
• Windows ACL enforcement and permission inheritance
• Configurable 1-to-4 node deployment model
• Multi-node high-availability posture for production workloads
• Elastic SMB metadata acceleration for Windows and VDI workloads
• Browser-based Admin UI for setup, shares, health, updates, and support reports
• CloudFormation deployment into your existing VPC
• Pay only for the Windows SMB shares and EFS GB of storage you actually use, billed hourly.

Roadrunner SMB software is billed through AWS Marketplace. Standard AWS infrastructure charges, including Amazon EFS and EC2/ECS resources, are billed separately by AWS.
