Architecture

App Modernization

Monolithic applications become bottlenecks. We decompose strategically, enabling independent teams and faster delivery.

The Problem

What It Looks Like

  • Monolithic application that's become unmaintainable
  • Can't deploy individual features — everything ships together
  • Scaling requires scaling the entire application
  • Single point of failure affects everything
  • Different teams blocked waiting for each other

What It Costs

  • Release cycles measured in months, not days
  • High coordination overhead across teams
  • Scaling costs 5-10x higher than necessary
  • Innovation blocked by architectural constraints
  • Team velocity decreases as application grows

The Real Risk: Monoliths don't scale — not the application, not the team. You'll hit a wall where adding engineers doesn't increase output. Competitors with modular architectures will ship 10x faster.

The Solution Approach: AI-Driven Decomposition

Use AI to understand your monolith before you break it apart. Extract domain boundaries intelligently, validate service boundaries, then modernize systematically.

1

Vibe Document: Understand the Current State (1-2 weeks)

Create the blueprint for decomposition by understanding your monolith's real structure and pain points.

What Gets Documented
  • • Current architecture, teams, and deployment model
  • • Pain points: slow deployments, scaling bottlenecks, coordination overhead
  • • Implicit business domains and how they interact
  • • Data flows and dependencies between systems
AI-Powered Analysis
  • Code Archaeology: Identify hidden service boundaries
  • Dependency Mapper: Visualize data and function coupling
  • Team Topology: Match code structure to team structure

Result: A shared understanding of what needs to change and why. This document guides all future decisions.

2

Validate: Prove Service Boundaries (1-2 weeks)

Don't guess at service boundaries. Validate them against real code to ensure clean extraction.

Validation Process
  • • Analyze code for cross-domain coupling
  • • Identify shared data structures and dependencies
  • • Map team responsibilities to proposed services
  • • Prioritize services by value and extraction difficulty
Deliverables
  • • Service map with clear boundaries
  • • Extraction roadmap (which services first)
  • • Data migration strategy per service
  • • Integration points and contracts

Why this works: AI analyzes coupling across 100k+ lines of code in hours. You get validated boundaries, not guesses. Prevents expensive extraction mistakes.

Context (Reverse-Engineering): Extract Domain Knowledge (2-4 weeks)

Before extracting a service, AI reverse-engineers what it actually does from the monolith code.

AI-Powered Archaeology
  • Code Comprehension: Understand service logic from monolith
  • Test Extraction: Reverse-engineer specs from existing tests
  • API Discovery: Identify current internal API contracts
  • Data Mapping: Track data flows and transformations
Deliverables
  • • Service specification document
  • • API contract (what data flows in/out)
  • • Database schema for service
  • • Business logic explanation

Why this matters: You understand exactly what behavior must be preserved when you extract. No surprises when the new service goes live.

4

Spec: Define Requirements & Architecture (2-3 weeks)

Design the new service using AI agents that enforce best practices and document decisions.

Requirements Agent
  • • Converts context doc into structured requirements
  • • Identifies edge cases and boundary conditions
  • • Documents API contracts for integration
Architecture Agent
  • • Proposes service architecture and tech stack
  • • Designs database schema from requirements
  • • Documents integration patterns and data flows

Result: Complete service specification with requirements, architecture, and API contracts. Your team can start building with confidence.

5

Testing & Security: Build Validation (2-3 weeks)

Generate tests and security validation before building the service. Catch issues early.

Testing Agent
  • • Generates test suite from requirements (70%+ coverage)
  • • Creates golden path tests for legacy behavior validation
  • • Defines performance and load test scenarios
Compliance Agent
  • • Validates against security standards (OWASP, encryption)
  • • Reviews API design for vulnerabilities
  • • Ensures data protection and compliance requirements

Why upfront: Build tests before implementation. Implementation follows test contracts. No late-stage surprises.

6

Operation: Build, Deploy & Validate (Ongoing)

Implement the service with AI-assisted development, then safely transition from monolith to microservice.

Implementation
  • • Code Generation Agent scaffolds service
  • • Builds against test suite (TDD)
  • • Integrates with existing APIs
Validation & Switchover
  • • Run against golden path tests
  • • Run new service parallel with monolith
  • • Compare outputs before switchover
Documentation
  • • Documentation Agent auto-generates docs
  • • Operation runbooks created
  • • Knowledge transferred to your team
