Monolith Modernisation

Incrementally decompose your monolith into well-bounded modules, without halting feature delivery or risking a costly rewrite.

Monolith Modernisation

Does this sound familiar?

Your monolith was the right call at launch. But invisible coupling has accumulated, and every change is now a gamble.

Release cycles longer than two weeks with rising rollback rates
Teams blocked by shared code ownership and merge conflicts
Fear of refactoring, nobody fully understands the side effects
Database tables with 60+ columns serving multiple contexts
New engineers taking months to become productive
A change in billing breaks checkout

Assess, design, implement, without the big bang

01

Assess

We analyse your codebase, data flows, and team structure to identify natural module boundaries. No code changes, just a clear picture of where coupling hurts most.

  • Static analysis + dependency graphs
  • Domain workshops with senior engineers
  • Coupling hotspot ranking
  • Ownership and data-flow mapping
02

Design

We define bounded contexts aligned to your business capabilities, not arbitrary technical layers, and validate them against real feature requests.

  • Bounded contexts per capability
  • Public API contract per module
  • Event contracts for async comms
  • Ownership model + team topology
03

Implement

We work alongside your teams to extract the first two modules, establishing patterns your engineers replicate for everything that follows. Monolith and new modules run side by side.

  • Incremental extraction, no freeze
  • Feature flags controlling cutover
  • CI, tests, and runbooks included
  • Pattern library your team reuses

What you walk away with

Architecture Assessment Report

Dependency graphs, coupling hotspots, data ownership conflicts, and a risk-rated component list, written for both technical leads and executive stakeholders.

Report

Module Boundary Map

A visual and documented breakdown of proposed bounded contexts, public contracts, ownership, and inter-module communication patterns. The blueprint for every future extraction.

Migration Roadmap

A quarter-by-quarter plan prioritising modules by business impact and extraction complexity, with effort estimates, risk mitigations, and clear milestones leadership can track.

Roadmap

Reference Implementation

The first two extracted modules, fully tested and running in production, complete with event contracts, CI pipelines, and monitoring, as the template for all subsequent work.

Common questions

01 Do we have to stop shipping features during the engagement?

No. Every extraction is incremental and feature-flagged. The monolith and the new modules run side by side, so feature delivery continues uninterrupted throughout the engagement.

02 How long before we see results?

The assessment delivers actionable insight in 2–3 weeks. The first extracted module typically lands in production within 8–12 weeks, and your team takes the pattern from there.

03 Do you take over the codebase or work with our team?

We embed with your engineers. The goal is capability transfer, not consulting dependency, your team owns the codebase and the pattern library when we leave.

04 What if our monolith uses a framework you don't know?

The patterns are framework-agnostic. We've modernised monoliths across Symfony, Laravel, and plain PHP, the approach translates cleanly to any codebase with clear seams.

05 How do you handle shared databases?

We map data ownership as part of the assessment and extract schemas in the same incremental way, private tables per context, event-carried state for cross-context reads, and a clear strangler migration plan for legacy shared tables.
