Application Modernization
Strangler-fig migration of legacy monoliths to cloud-native architecture — rehost, replatform, refactor, or replace per workload, not by ideology. Dependency mapping, API-first service boundaries, CI/CD pipelines, and incremental reversible steps that deliver value before the full programme completes.
Overview
Most business software was built for a world that no longer exists. Monoliths that will not scale. Languages nobody supports anymore. Release cycles measured in quarters. Application modernisation moves legacy estates onto cloud-native foundations without throwing away the logic that makes money. We map what each application does and how it couples to everything else, then pick the cheapest path that actually removes the pain — rehost, replatform, refactor, or replace. The goal: shorter release cycles, lower run cost, and a system your team can change without fear.
Clevertek scopes every engagement to your environment — capacity, sites, compliance and support model — so you get a tailored plan rather than a fixed SKU. Pricing is quote-only, and our solutions architects will work through your requirements before any proposal.
Our approach
We assess your entire application portfolio, rank every application by business value and technical risk, and produce a sequenced modernisation roadmap. Then we execute in reversible steps: containerising without rewriting, breaking monoliths into services only where it earns its keep, and leaving alone what is not hurting you.
Why work with us
Pragmatic, not purist
We do not push cloud-native for its own sake. Every decision is driven by measurable business outcomes, not architectural fashion.
Incremental, reversible steps
Each phase ships value within weeks using strangler-fig patterns. You see progress, validate assumptions, and adjust scope.
Risk-managed throughout
Rollback plans and reversible steps ensure business continuity. Modernisation never means stopping the business.
Key benefits
What this solution delivers for your business.
Faster release cycles
Move from quarterly releases to continuous delivery with automated CI/CD and containerised deployments.
Lower operational cost
Right-size workloads for cloud and managed services. Reduce infrastructure and licensing spend.
Easier talent retention
Modern stacks attract and retain engineering talent better than legacy platforms nobody wants to maintain.
What's included
Part of this managed service.
Portfolio assessment
We inventory applications, rank by business value and technical risk, and produce a roadmap finance can approve.
- Dependency and coupling mapping
- Business value versus technical debt scoring
- Sequenced multi-phase roadmap
- Risk and cost projections
Replatforming
Move to managed services and containers where a full rewrite is not justified. Capture most benefits at lower cost.
- Lift to managed databases
- Containerisation without code changes
- Reduced patching and ops burden
- Cloud-native compatibility
Refactoring
Break monoliths into well-defined services around the parts that change most often.
- Strangler-fig incremental migration
- API-first service boundaries
- Incremental database decomposition
- Reversible, testable steps
Measurable outcomes
Modernisation is not complete until release cadence, cost, and incident frequency show measurable improvement.
- Shortened release cycles
- Lower infrastructure cost
- Fewer production incidents
- Improved team velocity
Where it helps
Real-world scenarios where this solution delivers measurable outcomes.
A core ERP that will not scale
Refactor the bottleneck modules behind APIs so the rest of the monolith keeps running while you modernise the parts that hurt.
A product nobody can safely change
Introduce tests and service boundaries around the riskiest module first. Changes stop being events.
Questions buyers actually ask
Do we have to rewrite everything?
Almost never. Rewriting working software is the most expensive and risky option. We sequence changes so each step pays for itself.
How long before we see a result?
The first reversible improvement ships in weeks, not years. The full sequence matches your risk appetite and budget.
Will our team be able to maintain it?
Yes. We hand over code your engineers can read, plus the guardrails that keep it safe after we leave.
