Accelerating Legacy to Cloud

AWS re:Invent 2025 once again will underscored its status as the leading forum for cloud innovation, where enterprises gather to explore new capabilities, refine transformation strategies and engage with emerging technologies. Within this landscape, mainframe modernization emerged as one of the core themes, driven by the pressing need to overcome skill shortages, mitigate aging infrastructure risks and advance digital capabilities.

Enterprises understand that legacy workloads do not simply represent technical debt; they often embody the business logic vital to revenue, compliance and operations. The challenge is not the desire to modernize, rather the ability to do so without disrupting production systems or eroding institutional knowledge. In this context, AWS mainframe modernization solutions and its partnership with mLogica provide a structured blueprint for transformation.

mLogica’s participation at re:Invent builds on this foundation and supplies the specialized expertise required for the most complex and historically underserved workloads.

mLogica and AWS have established a partnership grounded in pragmatic modernization, scalable automation and a shared commitment to enterprise resilience. As part of the AWS Mainframe Modernization partner community, mLogica supports organizations facing the difficult realities of converting non-standard legacy artifacts, integrating critical systems and transitioning long-standing operational processes into a cloud-native environment.

Leveraging mLogica’s automated refactoring capabilities for Assembler, Easytrieve, Telon and others, as part of the LIBER*M Modernization Platform, signals a major leap forward for large enterprise organizations. For years, Assembler modernization was viewed as either too risky or too costly to automate. By integrating mLogica’s capabilities into AWS Mainframe Modernization framework, enterprises can now convert Assembler programs into structured, maintainable COBOL or Java that aligns with modern operational models. This expands the modernization universe beyond conventional COBOL-only estates and reinforces the depth of the partnership.

Beyond Assembler, mLogica’s expertise in Easytrieve, Telon, IMS, IDMS and other specialized technologies positions it as a natural complement to AWS’s cloud platform. Many enterprises discovered during their modernization assessments that these “exotic components” comprise the final barriers to full retirement of mainframe footprints. mLogica and AWS address these challenges together, ensuring modernization programs are not abandoned prematurely or re-scoped due to technology blind spots.

The drivers behind modernization are well understood: rising operational costs, shrinking legacy talent pools, escalating security expectations and the need to adopt agile development practices. Yet the obstacles remain significant. Assembler applications, IMS hierarchical databases and Telon-generated systems frequently lack documentation and depend on knowledge that is no longer available within the organization. Traditional modernization tools often bypass these components, leaving enterprises with partial transformations that still rely on expensive mainframe infrastructure.

mLogica emphasizes that the “last mile” of modernization is not a metaphor but a technical reality. It involves precisely these niche technologies that continue to run high-volume financial transactions, logistics systems, manufacturing operations and national-scale services. The partnership between AWS and mLogica directly targets these barriers, offering structured methodologies to uncover hidden dependencies, assess code behavior and convert or integrate legacy workloads without eroding mission-critical functionality.

mLogica brings a discipline to modernization that is grounded in automation, supported by decades of field experience and informed by the breadth of technology embedded in global mainframes. Its LIBER* Modernization Suite enables enterprises to progress from assessment to deployment through consistent, repeatable phases.

What distinguishes mLogica’s approach is its focus on full-stack modernization rather than code translation alone. Legacy systems often include custom utilities, embedded scripting, operational workflows and data formats that are intertwined with application logic. mLogica engineers evaluate each component holistically, ensuring that the migration path accounts for operational dependencies that might otherwise stall transformation efforts. This methodology integrates directly into AWS services strengthening both modernization velocity and cloud-native readiness.

AWS offers the scalable foundation required for enterprises seeking to modernize high-value workloads. Through AWS mainframe modernization solutions, organizations gain access to refactoring and replatforming pathways that support automated language transformation, managed runtimes, DevOps integration and extensive observability. These capabilities help reduce the operational burden associated with maintaining monolithic architectures and enable teams to move toward iterative, agile development practices.

mLogica’s role in this ecosystem is to extend AWS capabilities so they address the full spectrum of mainframe technologies. For example, mLogica supports the Assembler conversion features within AWS’s automated refactoring pipeline, enabling organizations to replace previously opaque low-level code with COBOL or Java optimized for cloud deployment. Similarly, mLogica’s modernization tooling helps translate Easytrieve and Telon logic into modern frameworks, allowing enterprise teams to extend, test and maintain applications with significantly greater transparency.

mLogica’s presence at re:Invent 2025 highlights its alignment with AWS’s modernization agenda and its role in helping organizations adopt more flexible, cost-effective architectures. The company plans to engage with executives, architects and modernization leaders seeking clarity on how to navigate Assembler, Easytrieve, Telon and IMS transitions. As generative AI and automation become more relevant to modernization strategies, mLogica presents forward-looking perspectives on how these technologies will accelerate code analysis, validation and testing in future modernization cycles.

The modernization horizon is shifting quickly. Organizations still anchored to legacy mainframes face rising support costs, narrow hiring pipelines and significant performance limitations. Those with Assembler, Easytrieve, Telon or IMS dependencies are particularly vulnerable to operational stagnation because their technology stacks depend on skills that are rapidly disappearing from the market.

mLogica and AWS offer a modernization model that reduces these risks and provides a structured pathway into scalable, secure and agile cloud environments. For leaders evaluating modernization strategies, now is the optimal time to assess existing workloads, quantify technical debt and define a transformation roadmap aligned to business priorities. The partnership between AWS and mLogica makes this achievable with greater predictability and significantly lower operational disruption.
