Application Modernization with a Systematic Approach.
Are your applications slow, difficult to maintain or not cloud-ready? With our Application Modernization services, we transform legacy systems to be ready for DevOps, API integration, and scalable operations.
Legacy systems slow down your growth – we make your platform modern and scalable.
Outdated applications, complex deployments and missing integrations are slowing down many IT platforms. Long release cycles, manual processes and high operating costs lead to costs, uncertainty and a growing technical debt burden.
At the same time, expectations are rising: agile development, API-first architectures and automated operation are now standard. Without targeted modernisation, IT becomes a risk – both technically and economically.
Application Modernization is the key to making existing systems fit for the future. With a well thought-out strategy, modern architecture and integrated automation, companies create the basis for stable, scalable and high-performance platforms – ready for what is to come.
Technology meets Application Modernization – for future-proof platform architectures.
- API-first architectures with REST, events & interface governance

- CI/CD mit GitLab, Azure DevOps, ArgoCD & Infrastructure as Code
- Containerisation with Kubernetes & Docker for scalable deployments
- Monitoring & Observability with Prometheus, Grafana, ELK
- Integration of logging & alerting in central SIEM systems
- Zero Downtime Releases & Canary Deployment Patterns
- Cloud-ready operation in the Sovereign Cloud & hybrid environments
What are the specific benefits?
Stronger architecture, automated workflows, and a future-ready platform.
How we support you.
We support you throughout the entire Application Modernization journey – from technical assessment and architecture design to implementation and reliable operations. Whether you are running legacy systems, monolithic applications, or historically grown platforms, together we define the optimal modernization roadmap – step by step, with minimal risk and long-term sustainability.
For our experts, Application Modernization is not a one-off project but a strategic transformation of your IT landscape. Through DevOps enablement, API-first integration, and scalable platform operations, we lay the foundation for agile development, secure deployments, and high-performance, cloud-ready architectures – if required, also in the CONVOTIS Sovereign Cloud, ensuring maximum control over data, infrastructure, and compliance.
The result: applications that not only run, but truly deliver impact.
We analyse your existing system landscape in a structured manner – including applications, data flows, interfaces and technical dependencies. In doing so, we assess the maintainability, release capability, scalability and security of your platform in relation to future requirements.
The aim is to highlight technological legacy issues and modernisation potential at the code, architecture and operational levels. We identify weak points with regard to API capability, cloud suitability and automation capability and formulate clear recommendations for the next steps in modernising your application.
Together, we develop a modernisation strategy tailored to your company, based on technical analysis, process understanding and strategic objectives. Whether refactoring individual modules, replatforming entire systems or developing new ones step by step: we create clarity about the best path for your application modernisation.
Refactoring for scalability means: modularisation of existing applications, containerised microservices and the use of cloud-native patterns - as the basis for a flexible, future-proof platform architecture.
We take into account technological dependencies, API readiness, infrastructure requirements and economic feasibility. The resulting roadmap prioritises measures, minimises risks and ensures a measurable impact - for a future-proof, scalable and maintainable application platform.
We design a modern, maintainable software architecture that are service-oriented, cloud-ready and with clear modularisation. The focus is on API-first principles, standardised interface formats (REST, events) and loose coupling between components. The aim is a flexible platform structure that enables rapid deployment, simple integration and technological development.
At the same time, we integrate existing systems and third-party solutions into the new architecture concept in a structured, comprehensible manner and designed for maximum reusability. This creates a stable foundation for a modern platform that maps your business logic and supports future growth.
We create the operational basis for the continuous delivery of your applications - with CI/CD pipelines, infrastructure as code and integrated toolchains such as Azure DevOps, GitLab or ArgoCD. These automated processes minimise manual intervention, reduce sources of error and significantly shorten release cycles.
We also support the introduction of DevOps principles in the team, including process definition, tool set selection and training. In this way, we combine development and operation in a stable process model that supports your application modernisation not only technically but also organisationally.

Still have questions?
Legacy systems cause high maintenance costs, security gaps and slow release cycles. They block innovation and make it difficult to integrate modern technologies. Application modernisation makes it possible to gradually transform existing applications into future-proof platforms: with modular architecture, automation and DevOps capability. This not only improves operations, but also creates the basis for greater agility, scalability and sustainable competitiveness.
Common approaches include rehosting (lift & shift), replatforming (technological relocation with customisation), refactoring (structured restructuring of the code) and new development (greenfield). The most suitable method depends on factors such as code quality, integration requirements, operating model and strategic goals. A well-founded preliminary analysis is crucial in order to avoid technical debt and define the best path to transformation.
Successful modernisation must be iterative, controlled and transparent. The risks of failure can be minimised with a clear roadmap, step-by-step migration paths and parallel operation. DevOps processes, automated tests and CI/CD pipelines ensure quality and accelerate transitions. The aim is modernisation "on the fly" – without system downtime or data loss, but with clearly visible progress.
We work in a technology-neutral way, but consistently in accordance with modern standards: API-first architectures, microservices, containerisation (Docker, Kubernetes), infrastructure as code (Terraform, Bicep) and observability (Prometheus, Grafana) are central building blocks. Toolchains such as Azure DevOps, GitLab or ArgoCD enable continuous delivery. The decisive factor is not the tool, but the interaction – tailored to your company, your processes and your IT strategy.
Application modernisation is an investment, but a highly impactful one. Specific costs depend on system size, complexity, objectives and existing infrastructure. Thanks to automation, lower maintenance costs and faster time-to-market, projects often amortise within a short period of time. We draw up a detailed business case in advance, analysing the costs and benefits so that decision-makers can make cost-effective decisions at all times.
