RF-SMART Goes Serverless to Power Global Reliability

Clearscale re-architected the company’s APIs on AWS with a multi-region serverless design, improving performance and reducing deployment risk.

Client Profile

Industry Supply Chain / Mobile Inventory Management

Overview

RF-SMART needed to ensure its APIs were highly reliable and globally available for customers relying on warehouse management systems. Clearscale delivered a multi-region, serverless architecture on AWS, improving consistency and reducing exposure to deployment errors. The solution enabled RF-SMART to operate with greater confidence and set the stage for future modernization.

Meet Our Hero

RF-SMART provides mobile inventory management solutions that integrate with warehouse management systems (WMS) across industries, from retail to healthcare. Its technology helps businesses track, manage, and optimize inventory with real-time accuracy. But RF-SMART faced challenges in keeping its APIs consistently available worldwide. Deployment errors created risks, and its legacy architecture was not designed for global failover. To ensure uninterrupted supply chain operations, RF-SMART needed a modern solution that could deliver reliability, consistency, and automation across regions.

The Goal

  • Implement a multi-region, serverless architecture for APIs
  • Reduce deployment errors through automation
  • Enable CI/CD with Blue/Green deployments
  • Ensure high reliability with global failover and geolocation routing.
  • Provide a secure, scalable foundation for future growth

The Challenge

Challenge 01 Inconsistent WMS performance across regions
Challenge 02 APIs lacked resiliency and exposed customers to disruptions
Challenge 03 Manual deployments increased risk of errors
Challenge 04 No global failover strategy to ensure uninterrupted service
Challenge 05 Needed to minimize downtime and strengthen customer trust

The Solution

Clearscale partnered with RF-SMART to build a globally resilient serverless architecture.

Step 01: Multi-Region Serverless Design

  • Implemented APIs with AWS Lambda and API Gateway
  • Used Amazon DynamoDB Global Tables for asynchronous replication
  • Designed routing with Amazon Route 53 for geolocation-based failover

Step 02: CI/CD Automation

  • Built CI/CD pipelines with AWS CodePipeline and CodeDeploy
  • Implemented Blue/Green deployments to minimize risk
  • Automated testing and release workflows

Step 03: Infrastructure as Code

  •  Applied Infrastructure as Code (IaC) principles to ensure consistent, repeatable deployments
  • Created a framework extendable to future applications

Step 04: Resiliency and Scalability

  • Delivered a high-availability environment across multiple AWS regions
  • Provided RF-SMART with a roadmap for further application refactoring

The Impact

Globally reliable APIs, ensuring uninterrupted WMS performance

Reduced deployment errors through Blue/Green CI/CD automation

High availability and resiliency, supported by multi-region design
Infrastructure as Code foundation, enabling consistency and scalability
Future-ready roadmap, allowing RF-SMART to extend the architecture to other applications
“The Clearscale team has enabled us to quickly meet our needs for increased reliability of our application. This allowed our development teams to continue their focus on the application’s functionality, which transforms our customers and changes lives.” — David Lomneck, Director of Development NetSuite, RF-SMART
