AI-Driven Application Modernization for Regulated Industries on AWS


In regulated industries, modernization is never just a technology upgrade. For healthcare and life sciences organizations, financial institutions and other compliance-heavy enterprises, legacy transformation must move faster without losing the controls that protect trust, resilience and regulatory integrity. That means balancing speed with governance, innovation with oversight, and AI acceleration with auditability.

Publicis Sapient helps organizations modernize core applications on AWS with that balance built in from the start. By combining AI-assisted modernization, human oversight, cloud-native engineering, modern data foundations and embedded security, we help enterprises transform legacy systems into scalable, compliant platforms ready for what comes next.

The goal is not simply to translate old code into a newer language. It is to create an AI-ready, cloud-native foundation that supports continuous change, stronger traceability and future innovation in environments where control matters as much as speed.

Why regulated industries need a different modernization model


Legacy technology creates familiar problems across industries: high maintenance costs, dependence on scarce skills, slow release cycles and fragmented data. But in regulated sectors, the stakes are higher. Core systems often support sensitive data, critical operations and business processes that must remain transparent, secure and defensible.

That is why modernization in these environments cannot be approached as a lift-and-shift exercise or a one-time code conversion project. Enterprises need a modernization model that supports:


For buyers in healthcare and life sciences, financial services and other highly governed sectors, the real question is not whether modernization can move faster. It is whether it can move faster while remaining explainable, testable and accountable.

Accelerate modernization with AI—without surrendering control


Publicis Sapient uses AI to make application modernization significantly faster and more practical, while keeping human intervention at the center of delivery. Using large language models, contextual knowledge and pre-built prompt libraries, teams can analyze existing code, generate target-state documentation, automate testing and transition applications toward modern architectures.

This approach helps address one of the biggest barriers in regulated modernization programs: the difficulty of understanding decades of legacy logic and translating it into usable specifications for modern engineering teams. Instead of treating AI as a black box, Publicis Sapient applies it to create practical outputs that improve transparency and execution. These include feature summaries, detailed specifications, transformed architecture, test cases, unit tests and automation test scripts.

Sapient Slingshot plays a central role in this process. Built on Bodhi, Publicis Sapient’s enterprise-ready AI platform on AWS, it turns existing code into verified specifications and generates modern software with full traceability. That matters in regulated environments, where modernization success depends not only on speed, but on the ability to show how changes were made, tested and validated.

Across more than 100 end-to-end modernization experiments, Publicis Sapient’s AI-enabled accelerators demonstrated the potential for more than 50% reduction in modernization costs, 50% fewer defects with expanded coverage of requirements and test cases, and a 50% increase in migration speed. Actual results vary by client context, but the direction is clear: AI can help enterprises modernize faster while strengthening quality and traceability.

Build secure AWS foundations for compliance-heavy transformation


In regulated industries, modernization cannot stop at the application layer. Long-term value depends on the quality of the cloud foundation underneath it.

Publicis Sapient helps enterprises establish secure, scalable AWS environments across strategy, mobilization, build, migration and operations. That includes cloud transformation strategy, foundation setup, database setup, infrastructure planning, FinOps management and secure cloud-native architecture. Security is embedded throughout the journey through data security, cloud-native security, security mesh and network security activities.

This foundation is critical because modern delivery requires more than a landing zone. It requires an environment that supports continuous change without creating new governance gaps. On AWS, Publicis Sapient helps organizations reduce legacy silos, improve resilience, dynamically scale resources and modernize with stronger operational confidence.

For regulated enterprises, that translates into a more practical path to modernization: one that supports both engineering velocity and enterprise control.

Turn legacy systems into AI-ready platforms


In healthcare and life sciences, modernization must support sensitive data, interoperability, reliability and seamless experiences across patients, clinicians, researchers and partners. In financial services, transformation must align with risk management, security, performance and the demands of highly scrutinized customer and advisor experiences. Across both sectors, the challenge is the same: legacy systems were not built for today’s pace of change or tomorrow’s AI ambitions.

Publicis Sapient approaches modernization as a connected transformation across Strategy, Product, Experience, Engineering and Data & AI. That means aligning application modernization to business outcomes, operating models and future AI opportunities rather than treating it as a standalone technology program.

A cloud-native architecture creates the flexibility to scale services, improve resilience and support modular delivery. Modern data foundations help unify fragmented information and make trusted data more usable across the enterprise. Together, these elements create the conditions for secure automation, real-time insight, personalization and future agentic AI use cases.

In other words, modernization becomes the platform for what comes next—not just the replacement of what came before.

Governance, traceability and responsible oversight by design


Publicis Sapient’s approach is designed for enterprises that need modernization with accountability built in. AI can accelerate documentation, code understanding, testing and delivery, but regulated organizations still need confidence that outputs are transparent, validated and aligned to internal and external requirements.

That is why human oversight is embedded throughout the modernization process. AI-generated outputs are designed to be reviewed, refined and validated by engineering teams, improving both quality and trust. Traceable specifications and automated testing help create a stronger record of how systems are evolving. DevOps engineering, infrastructure as code, standardized environments, continuous integration and Agile DevSecOps practices help extend governance across the delivery lifecycle.

Observability also matters. Publicis Sapient brings full-stack monitoring, logging, alerting, reporting and dashboarding to modern AWS environments so teams can improve visibility into system behavior, identify issues earlier and support more resilient operations in production.

The result is a modernization journey that does not trade rigor for momentum. It uses AI to increase both.

Industry-specific modernization with enterprise AWS strength


Publicis Sapient brings deep transformation experience across industries together with a strong AWS relationship designed to accelerate enterprise modernization. As an AWS Premier Tier Services Partner with broad specializations, a five-year global strategic collaboration agreement focused on IT modernization and a large base of AWS-trained professionals, Publicis Sapient helps organizations move from roadmap to execution with less friction.

That matters in regulated sectors, where enterprises are looking for more than technical migration support. They need a partner that can connect cloud, engineering, security, data and AI into one governed modernization journey.

Publicis Sapient combines that end-to-end capability with enterprise platforms built for production. Bodhi helps organizations deploy and scale AI use cases with enterprise-grade safeguards, data protections and responsible AI principles. Sapient Slingshot helps modernize legacy systems with speed and full traceability. Together on AWS, they help regulated enterprises move beyond isolated pilots and toward production-ready transformation.

Modernize for innovation you can trust


The strongest modernization programs in regulated industries do more than retire aging systems. They create a secure, governed and adaptable foundation for continuous innovation.

Publicis Sapient helps healthcare and life sciences organizations, financial institutions and other compliance-heavy enterprises modernize core systems on AWS with AI-assisted delivery, embedded security, modern data foundations and human oversight throughout. The outcome is faster modernization with stronger quality, clearer traceability and a more durable platform for future AI-driven growth.
