Microservices Modernization Assessment

An evaluation of where your organization actually is on the path from monolith to genuinely decomposed services — and a sequenced, evidence-based plan for closing the gap. We distinguish genuine service independence from distributed coupling, map team topology alignment, and identify the next meaningful steps that don't require rewriting everything at once.

The Situation

A CTO or VP Engineering at a mid-market or enterprise organization that has been "doing microservices" for two to four years — and is now dealing with all the operational complexity of a distributed system without the independence benefits they were promised. Services deploy together because the team is afraid to deploy them separately. API contracts were never formalized. The architecture called "microservices" is functionally a distributed monolith, and nobody has named it clearly.

The Value

By assessing the current service architecture against decomposition principles — deployment independence, data ownership, API contract stability, team topology alignment — this engagement produces an honest picture of where the organization stands, and a sequenced next-steps plan that improves the architecture incrementally rather than proposing a rewrite.

How It Works

  1. Service Inventory & Dependency Mapping — all services cataloged with ownership, deployment frequency, and dependency documentation.
  2. Decomposition Analysis & Team Topology Review — each service boundary scored; coupling heat map produced; team ownership alignment reviewed.
  3. Remediation Path & Investment Rationale — for multi-domain environments, remediation paths and investment rationale developed and sequenced.

What You Get

DeliverableDescriptionValue to You
Service MapInventory of all services with ownership, deployment frequency, and dependency documentationEstablishes the current state with specificity — most organizations don't have this documented
Decomposition AnalysisScoring of each service boundary against deployment independence, data ownership, and contract stabilityNames which services are genuinely decomposed vs. distributed monolith components
Coupling Heat MapStructured representation of coupling density and type across the service landscapeIdentifies the highest-leverage places to invest remediation effort
Team Topology Alignment ReviewAssessment of whether team ownership supports or contradicts intended service boundariesSurfaces the organizational dimension architecture diagrams don't show
Recommended Next StepsSequenced remediation plan with investment rationale per stepA path forward without a big-bang rewrite

Typical Duration

3–4 weeks. A single product domain with a moderate service count (under 20) and accessible documentation completes in 3 weeks. Multi-domain environments or legacy integration layers typically require 4 weeks.

Why Now

The cost of a distributed monolith is paid continuously: slow deployments, high coordination overhead, fragile releases, and an architecture that makes independent scaling impossible. Each new service added without addressing structural issues adds coupling surface — organizations that address decomposition while it is still tractable spend significantly less than those who wait.

Grounded in Real Experience

Grounded in Tony’s tenure as CTO of Professional Access, where he expanded the firm's practice into Magento, commercetools, and custom microservices for enterprise commerce clients.
