Services / App Modernization
Evolve the systems that run your business.
Your core applications hold decades of business logic. We modernise them incrementally — strangling the monolith, decomposing domains and replatforming onto containers and managed services — so value flows from month one, not year three.
Capabilities
What we deliver
Portfolio rationalisation
Application scoring across business value, technical health and risk to prioritise what to retire, retain or rebuild.
Monolith decomposition
Strangler-fig patterns and domain-driven design to carve out services safely, one capability at a time.
Replatforming
Java, .NET and legacy runtimes containerised onto GKE, Cloud Run, EKS and ECS with minimal code change.
Mainframe modernisation
COBOL and batch workloads refactored or emulated with AWS Mainframe Modernization and Google Dual Run.
API enablement
Expose legacy capabilities as secure, governed APIs to unlock digital channels and partners.
AI-assisted refactoring
Gemini Code Assist and Amazon Q accelerate code analysis, test generation and language translation.
Technology
Native on both clouds
Google Cloud
AWS

FAQ
Common questions
Do we have to rewrite everything?
Rarely. Most value comes from targeted refactoring and replatforming; full rewrites are reserved for where they clearly pay back.
How do you keep the lights on during modernisation?
Incremental delivery and parallel running mean the legacy system keeps serving customers until each capability is proven.
