02 — Application Modernization
From legacy applications to modern architecture.
Your business applications carry years of know-how — but outdated systems cost money, slow you down and create risk. We modernize them step by step, so you lower costs and move faster, without ever stopping the business.
For your business
What your company gains
Less maintenance of outdated systems and fewer expensive emergency fixes.
New products, services and integrations reach your customers in weeks instead of months.
No risky “big switch” and fewer outages — the business keeps running throughout.
The shift
What changes when you modernize
Legacy today
- A monolith where every change is risky
- Manual deployments and planned downtime
- Outdated frameworks without security updates
- Data locked in silos, no APIs
- Knowledge held by a few people
- Hard to connect to online services and partners
Modern target
- Modular services with clear boundaries
- Automated CI/CD and zero-downtime releases
- Supported, secure technology stack
- Open, documented and secured APIs
- Documentation, tests and observability
- Ready for web, mobile and partner integrations
Our approach
Modernization without the big-bang risk
Assessment & roadmap
We analyse code, architecture, dependencies and risks, then choose the right path per component: rehost, replatform, refactor or rebuild.
API-first integration
We expose existing functions through secure APIs, so new digital services can be built now — before the legacy core is replaced.
Gradual replacement
Module by module, old and new run side by side (strangler pattern) until the legacy system can be switched off safely.
Containers & cloud
Containerization and orchestration on Kubernetes or OpenShift — on-premises, hybrid or in the public cloud.
Data migration
Planned, validated data migration with reconciliation and rollback plans, so no record is lost.
DevSecOps
Automated pipelines, tests, security scanning and monitoring built into the delivery process from day one.
Process
Five steps to a modern platform
Assess
Understand the system, its users and its risks.
Stabilize
Version control, backups, monitoring and a safe release process.
Decouple
Introduce APIs and separate the first modules.
Modernize
Rebuild or refactor module by module on the new platform.
Operate
Run, observe and continuously improve the new architecture.
Example
Core banking system, re-architected
A financial institution relied on a monolithic core system that made every change slow and risky. We moved it to a microservices architecture on the OpenShift platform with event streaming — module by module, while the bank continued to operate.
FAQ
Questions about modernization
Do we have to rewrite the whole application?
Rarely. Most systems have parts that work well and parts that block progress. We modernize where it brings the most value and keep the rest running until it makes sense to replace it.
How long does modernization take?
It depends on the size of the system, but you see the first results — APIs, automated releases, a first modernized module — within weeks, not years.
Will our users notice the change?
Only in a positive way. Old and new components run side by side and releases are made without downtime, so daily work continues uninterrupted.
