From Insight to Optimization in Four Steps

A successful modernization begins with understanding what’s already in place. From there, we transform applications step by step into a future-proof, cloud-native environment.

01 Assess & Analyze
Reverse Architect Agent

We’ll thoroughly assess your application and architecture. We’ll use everything you already have in place—both in terms of technology and business logic—as a starting point. The information below will help us quickly get to the heart of your system:

  • Business Objectives & Strategy
  • Processes, Rules, and Policies
  • Dependencies & Architecture
  • Technology Landscape
  • Compliance & Security

Our AI solutions help us quickly gain insight into complex and often inadequately documented applications.

02 Modernize
Refactor / Rebuild Agents

We transform outdated application components into modern, scalable solutions.
Our AI agents help refactor and rebuild applications and make existing business logic reusable through modern integration APIs.

03 Migrate
Replatform Agent

We deploy applications in a controlled manner to the desired cloud or Kubernetes environment.
With automated CI/CD pipelines and Zero Trust security boundaries, we make migrations more secure, consistent, and scalable.

04 Manage & Optimize
Platform Engineering

Modernization doesn't stop once the application has been migrated.
We manage and optimize applications across public and private clouds using cloud-native architecture, continuous observability, and GitOps.

"To maintain our leading market position, the transition to a modern web architecture was a logical choice. In SUE, we found both the technical expertise and the strategic partner we needed to move quickly without taking unnecessary risks. This allows us to condense a multi-year transformation into a single year and continue building a scalable, intelligent SaaS future."

How SUE Helps ISVs Make the Transition to SaaS

The transition from traditional software to a SaaS model requires more than just hosting an application in the cloud. The architecture must support scalability, continuous development, and a consistent user experience. SUE helps ISVs modernize their applications by decoupling the user interface from the underlying business logic. This creates a more flexible architecture that is easier to develop, integrate, and manage as a SaaS platform. For CarWise, SUE applied this approach to modernize the application architecture and create a more solid foundation for further development.

How SUE Private Equity Provides Support

SUE assists private equity firms with vendor due diligence to quickly gain insight into the technological foundation of an investment. We identify risks, scalability, and opportunities for improvement. Our assessment covers areas such as application architecture, cloud, security, and technical scalability. This provides a clear picture of the current situation and a concrete roadmap for modernization, consolidation, and further growth.

Frequently asked questions

All frequently asked questions
Rehosting (lift-and-shift) moves an application 1-to-1 to the cloud with minimal modifications. Replatforming optimizes specific components (such as the transition to managed cloud databases) without changing the core code. Refactoring completely redesigns the application into a scalable, cloud-native microservices architecture. With our Application Modernization Assessment, we determine for each application exactly which approach delivers the highest ROI and the lowest risks.
Rebuilding an application entirely from scratch is often a multi-year project involving high costs and significant risks. By modernizing your existing code, you retain the valuable business logic that has been built up over the years while eliminating the outdated technology surrounding it. SUE helps organizations transform their existing codebase in a targeted manner into a cloud-native architecture. This allows you to benefit much more quickly from modern scalability, security, and performance, without the uncertainty of a “big bang” build-from-scratch project.
Technical debt arises when old code, outdated frameworks, and temporary “quick fixes” accumulate over the years. This makes applications insecure, slow, and extremely expensive to maintain. Furthermore, new talent for legacy languages is becoming increasingly scarce, and your current developers are primarily focused on fixing bugs rather than innovating. With our Application Modernization Assessment, we precisely identify your hidden technical debt and map out a concrete plan for refactoring the code. This reduces operational costs and allows your IT team to refocus on building new, value-adding features.
