Application Decomposition Strategy Template
Documenting how applications are decomposed into services using domain-driven design boundaries
The Application Decomposition Strategy template provides a structured approach to documenting how applications are decomposed into services using domain-driven design boundaries.
Template Sections
This template includes 7 sections.
Decomposition Overview
Describe the motivation for decomposition, the current state (monolith or distributed), and the target service...
Current State Architecture
Diagram section
Target State Architecture
Diagram section
Decomposition Pattern
Document the chosen decomposition approach (strangler fig, branch by abstraction, parallel run) and the rationale
Current to Target Gap Analysis
Identify the gaps between current and target architectures across technology, team structure, and data ownership
Migration Steps
Document the phased migration plan from current to target state, with dependencies and success criteria
Decomposition Risks
Document risks including distributed system complexity, data consistency challenges, and team readiness
