Janus AI Studio Professional Services

TSRI’s Migration and Modernization service helps enterprises transform complex mainframe and legacy systems into secure, scalable, and cloud-native solutions on AWS—without disrupting ongoing business operations. With nearly 30 years of experience modernizing mission-critical systems, TSRI combines deep domain expertise with JANUS Studio®, its advanced automation platform, to deliver predictable, low-risk modernization at enterprise scale.

Many organizations running COBOL, PL/I, PowerBuilder, RPG, or other legacy technologies face rising infrastructure costs, shrinking talent pools, vendor lock-in, and mounting technical debt. Traditional approaches such as rehosting (“lift and shift”) or emulation often preserve legacy constraints in the cloud, limiting agility and perpetuating high total cost of ownership. Manual rewrites, on the other hand, are risky, expensive, and time-consuming, frequently taking years and introducing operational disruption.

TSRI takes a fundamentally different approach: automated code transformation and refactoring that produces clean, maintainable, and cloud-aligned applications optimized for AWS. Using JANUS Studio®, TSRI performs a comprehensive assessment of the existing application portfolio, including code quality, architecture, dependencies, data structures, and business rules. This data-driven analysis informs a precise modernization roadmap aligned with AWS Well-Architected Framework principles.

The transformation process leverages near-100% automation to translate legacy code into modern languages such as Java or C#, while restructuring the application architecture to support microservices, APIs, containers, and serverless capabilities where appropriate. Instead of replicating outdated design patterns, TSRI delivers scalable, modular codebases that integrate seamlessly with AWS services including Amazon EC2, ECS, EKS, Lambda, RDS, and other managed services. This ensures improved performance, security, resilience, and elasticity in the cloud environment.

A key differentiator of TSRI’s approach is business continuity. Because automation preserves embedded business logic and rules with high fidelity, organizations can modernize without losing decades of institutional knowledge encoded in their systems. Parallel testing, validation, and incremental deployment strategies minimize operational risk and support smooth cutover to AWS environments.

Beyond initial migration, TSRI offers a Continuous Modernization model that treats modernization as an ongoing operational capability rather than a one-time project. This OpEx-based approach enables enterprises to iteratively optimize applications, reduce technical debt, enhance security posture, and adopt new AWS innovations over time. The result is a future-ready technology foundation that supports digital transformation initiatives, advanced analytics, AI/ML integration, and evolving regulatory requirements.

By eliminating proprietary runtime dependencies and vendor lock-in, TSRI expands access to modern development talent and improves long-term maintainability. Automated transformation significantly accelerates timelines—often reducing multi-year efforts to months—while lowering total cost of ownership compared to manual rewrites or extended mainframe retention.

The outcome is not simply migration to AWS, but true modernization: clean, cloud-native applications designed for scalability, resilience, security, and innovation. Enterprises gain the agility to respond to market demands, the financial flexibility of optimized cloud consumption, and the confidence that their most critical systems are built on a sustainable, future-proof architecture.

Through proven methodology, automation-driven precision, and deep expertise in both legacy platforms and AWS cloud architectures, TSRI and JANUS Studio® enable organizations to modernize with certainty—transforming legacy complexity into cloud-enabled competitive advantage.
