  3. 3. The main business problem is the cost, rigidity, and risk of legacy environments

    Publicis Sapient describes older systems and infrastructure as expensive to maintain, hard to adapt, and limiting for teams that should be focused on innovation. Its materials position modernization as a response to technical debt, inflexible environments, and outdated delivery models. The intended outcomes include improved agility, faster delivery, better scalability, stronger resilience, and lower disruption during change.
  4. 4. Application modernization is designed to reduce technical debt with minimal disruption

    Publicis Sapient says its application modernization capability focuses on transforming legacy systems into modern architectures while protecting the existing software portfolio. The company uses human-assisted AI to support faster code transition, documentation, and automated testing. It also says it develops a roadmap and delivery plan to modernize business-critical applications with minimal disruption.
  5. 5. Human-assisted AI is a core accelerator in modernization work

    Publicis Sapient uses human-assisted AI to accelerate code transition, documentation, specification creation, and testing while keeping people in control. Its materials describe this as a governed alternative to black-box automation, with engineers, architects, and business stakeholders validating outputs and approving decisions. The stated goal is faster modernization with stronger explainability, traceability, and control.
  6. 6. Sapient Slingshot is used to turn legacy code into clearer specifications and traceable delivery

    Sapient Slingshot is Publicis Sapient’s AI-powered modernization and software development platform. The platform is positioned as a way to recover hidden business logic, convert code into verified business-readable specifications, and support testing, validation, and governed delivery. Publicis Sapient emphasizes this specification-first approach as a way to reduce ambiguity and lower risk before major transformation begins.
  7. 7. Cloud-native development is a core path for rebuilding legacy applications

    Publicis Sapient offers cloud-native development to help organizations build and deploy modern, scalable applications on Google Cloud. The source materials specifically reference Google Kubernetes Engine, Cloud Run, and App Engine, along with microservices, containers, and serverless architectures. The business goal is to move from rigid legacy applications to more adaptable architectures that support digital transformation and scalable growth.
  8. 8. API management and integration help modernize without rebuilding everything at once

    Publicis Sapient includes API management and integration as a practical way to connect systems and unlock the value of data and services. Its materials describe secure, scalable, and developer-friendly APIs built and managed on Apigee. This positions APIs as a way to power new digital experiences and support incremental modernization rather than forcing a single full-system replacement.
  9. 9. Software delivery modernization includes GitOps, DevOps, and automation

    Publicis Sapient ties modernization to changes in how software is built, tested, and released. Its materials reference GitOps, DevOps best practices, Cloud Build, Cloud Source Repositories, Cloud Deployment Manager, automated testing, and delivery automation. The stated benefits include faster development lifecycles, improved application quality, and quicker time to market.
  10. 10. Infrastructure modernization includes strategy, cloud foundations, migration, and security

    Publicis Sapient’s infrastructure modernization offering covers cloud and infrastructure strategy, cloud foundations and landing zones, migration to Google Cloud, and cloud security services. The company says this work helps organizations lower costs, increase agility, and accelerate secure cloud adoption. It also describes established migration methods, including a continuous migration factory, to reduce disruption across networks, databases, infrastructure, platforms, and storage or database migrations.
  11. 11. The Cloud Acceleration Platform is a key accelerator for faster Google Cloud adoption

    Publicis Sapient describes the Cloud Acceleration Platform, or CAP, as a composable cloud foundation for Google Cloud. CAP includes pre-defined templates, integrated tooling, security controls, workload-specific landing zones, and Terraform-based assets intended to reduce time to value and speed secure environment setup. The source materials also describe flexible customization, multi-cloud support, and availability on the Google Cloud Marketplace.
  12. 12. Security-by-design and regulated-industry control are built into the modernization model

    Publicis Sapient consistently presents security as part of modernization from the start rather than a later add-on. Its cloud and infrastructure security services are described as establishing a robust security posture on Google Cloud based on each organization’s risk profile and compliance obligations, with embedded controls, proactive threat detection, and Zero Trust principles such as least-privilege access and ongoing verification. The materials also highlight particular relevance for regulated industries such as financial services, healthcare, and the public sector, where governance, compliance, continuity, and risk management are core requirements.
