Application modernization
Your core systems are the backbone of the business, but they often hold back the pace of innovation. With application modernization you can transform technical debt and complexity into modern, scalable and cost‑effective platforms that drive digital development instead of hindering it.
What you get with application modernization
Many companies are stuck in an environment of legacy systems, manual processes and high costs for operations and licenses. The challenges are well known:
- Outdated technology and technical debt
- High maintenance costs
- Security risks and compliance challenges
- Silo thinking and lack of integration
Create a modern, modular architecture where your business‑critical applications can evolve at the pace of your business:
- Less technical debt when you modernize step by step and remove what no longer creates value.
- Lower costs as operations, licenses, and maintenance are optimized through smarter platforms.
- Better security and control by replacing outdated technology and ensuring compliance.
- More capacity for innovation when resources are freed up for new digital initiatives instead of maintenance.
Application modernization tailored to your business
Upgrading legacy systems is not just about technology. It’s about creating better conditions for growth, efficiency and stable operations. Modernization happens incrementally, with clear priorities and minimal impact on business operations.
Technologies we often use:
- Azure App Service / Azure Kubernetes Service (AKS): cloud‑based hosting for modernized applications.
- Azure DevOps / GitHub Actions: controlled release and version management.
- Application Insights / Azure Monitor: monitoring and operational reliability.
- .NET 8 / Java Spring Boot / Python FastAPI: modern and sustainable backend stack.
Typical deliverables:
- A modernization plan per system with prioritization based on business value and risk.
- Replatformed applications: moved to the cloud while maintaining functionality.
- Automated CI/CD pipelines for testing, release and operations.
- Monitoring and alert dashboards for application health and performance.
Common roles involved:
Solution Architect, Cloud Engineer, DevOps Engineer and Application Owner.
By mapping applications, assessing risks and prioritizing efforts, you create a clear, data‑driven roadmap for modernization. The result is a controlled journey that minimizes risk and maximizes business value, both short‑ and long‑term.
Technologies we often use:
- CAST Highlight / LeanIX / Azure Migrate: system inventory and technical debt analysis.
- Power BI / Fabric: analysis and visualization of cost and portfolio data.
- Excel / Miro / PowerPoint roadmap tools: structured planning and communicative roadmaps.
Typical deliverables:
- Inventory of the application portfolio including functionality, technology and dependencies.
- Risk and business‑value analysis for each system.
- Modernization roadmap (3–18 months) with clear steps and priorities.
- Decision support for CIO and CFO ahead of investments and initiatives.
Common roles involved:
Enterprise Architect, Advisory Lead, PMO and Business Analyst.
Through cloud adoption, refactoring and API‑fying, we strengthen both operational reliability and development speed. The result is an IT environment that is stable enough for mission‑critical processes, and at the same time flexible enough for rapid innovation.
Technologies we often use:
- Containerization (Docker, AKS): standardized and portable runtime environments.
- Azure API Management / REST / GraphQL: API‑fying and modern access to legacy applications.
- Serverless Functions (Azure Functions): flexible logic without need for own infrastructure.
- Infrastructure as Code (Terraform / Bicep): controlled and reproducible environment setup.
Typical deliverables:
- Refactored applications with modern and sustainable codebase.
- API‑layers on top of existing systems for easier integration and further development.
- Cloud architecture with redundancy, security and scalability.
- DevOps pipeline enabling faster, safer and more predictable releases.
Common roles involved:
Modernization Engineer (.NET/Java), Integration Architect, DevOps Engineer and QA Lead.
Modernization yields concrete effects: lower operational costs, higher availability, improved quality and an IT environment that better supports business objectives. The results become apparent in economy, stability and user experience.
Technologies we often use:
- Azure Cost Management + Power BI: continuous cost monitoring and analysis.
- Azure Application Insights / Log Analytics: measuring quality, performance and incident patterns.
- ITSM systems (ServiceNow / Jira Service Management): improved incident, change and release management.
Typical deliverables:
- TCO report and ROI calculation for each modernized system.
- Improved SLA and availability, measured before and after modernization efforts.
- Real‑time quality reporting via Power BI.
- Optimization recommendations for licenses, servers and storage.
Common roles involved:
Program Manager, Finance Controller, QA/Test Lead and Operations Manager.
By modernizing legacy solutions and replacing them with scalable, cloud‑based platforms, technical debt turns into strategic assets. The organization gains a stable foundation that makes it easier to deliver value, innovate and evolve over time.
Technologies we often use:
- Azure Landing Zones / Well‑Architected Framework: sustainable and secure cloud base.
- Power Platform / Low‑code modern apps: quick replacement of simpler legacy applications.
- Fabric & Synapse: data integration, modeling and reporting.
- Azure AI Services: future‑proof solutions such as anomaly detection, automation and analytics.
Typical deliverables:
- New cloud‑based applications that replace older, outdated systems.
- A common integration and data platform for the entire organization.
- A roadmap for AI‑ and data‑driven applications tailored to business goals.
- Knowledge transfer and governance structure for the customer’s IT organization.
Common roles involved:
Enterprise Architect, Cloud Strategy Lead, Data Architect and Change Manager.
