AWS Mainframe Modernization
heirloom on aws
Overview
Heirloom Applications Execute on Every AWS Cloud Service
Platform lock-in ends here. While other solutions force you into specific AWS services, Heirloom's proven mainframe application modernization technology delivers true AWS flexibility. Our platform-agnostic approach means your modernized applications run natively on any AWS platform—including App Runner, Elastic Beanstalk, EC2, or EKS—without compromise.
Built on AWS from day one, Heirloom gives you complete control over your modernization journey. Deploy once, run anywhere, pivot anytime. Turn the dial between replatforming for immediate cost savings and refactoring for long-term agility. Scale when you need to, and integrate with whatever AWS services drive your innovation.
The result? Mainframe workloads that exploit the full native capabilities of your preferred AWS platforms while delivering sub-second response times at enterprise scale. This is modernization without architectural constraints—your applications, every AWS platform, complete strategic optionality.

Case study
From 1980s Mainframe to AWS Cloud-First Strategy
Venerable faced a critical challenge: modernizing a custom-built system with 1980s roots to meet growth objectives and rising customer expectations. The complexity was extreme, but their cloud-first strategy demanded migration.
Using Heirloom's technology, Venerable successfully migrated their core application to AWS, eliminating their mainframe dependency entirely. The modernized system has been running in production since June 2020, handling high transaction volumes while maintaining the business logic integrity that decades of refinement had built.
Showcase
Enterprise Performance at Cloud Scale
Numbers tell the story of true mainframe-class performance on AWS infrastructure. Our TPC-C benchmark demonstrates what modernized applications can achieve when freed from platform constraints.
Performance Metrics:
- 22,500 concurrent user sessions
- Sub-second response times sustained
- 1,018 transactions per second throughput
- Equivalent to 15,200 MIPS capacity
- 105 MIPS per CPU core efficiency
This isn't theoretical performance—it's production-proven capability running on standard AWS infrastructure. Whether you're processing high-volume transactions, running complex batch jobs, or serving demanding user workloads, Heirloom-modernized applications deliver mainframe reliability with cloud economics.
The benchmark proves that AWS migration doesn't mean performance compromise. It means performance optimization with the flexibility to scale, integrate, and innovate using every AWS service in your toolkit.
