SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams decide whether and how to break down a monolithic application into microservices by identifying logical boundaries based on business capabilities and domain-driven design principles.

Core Features & Use Cases

Monolith Analysis: Evaluates the suitability of decomposing a system.
Bounded Context Identification: Uses Domain-Driven Design (DDD) to find natural seams.
Dependency Mapping: Visualizes inter-service communication.
Event Contract Design: Defines schemas for inter-service events.
Decomposition Sequencing: Provides a strategic order for extraction.
Anti-Pattern Avoidance: Highlights common pitfalls like distributed monoliths.
Use Case: A team is considering migrating a large e-commerce monolith to microservices. They will use this Skill to identify potential service boundaries for areas like 'Orders', 'Users', and 'Products', and plan the extraction sequence.

Quick Start

Use the service-decomposition skill to analyze the current monolith and identify potential service boundaries for the 'user-management' domain.

FAQPage Schema

How do I decompose a monolith into microservices?▼

To decompose a monolith into microservices, you identify business capabilities and bounded contexts using Domain-Driven Design principles. This process maps system dependencies, designs event contracts for inter-service communication, and sequences the extraction strategy to avoid distributed monoliths.

How does Domain-Driven Design identify bounded contexts for microservices?▼

Domain-Driven Design identifies bounded contexts by analyzing the monolith to find natural seams matching business capabilities. This reveals logical service boundaries for domains like 'Orders' and 'Users', ensuring microservices are decoupled and independently deployable.

What is the best way to sequence service extraction from a monolith?▼

The best way to sequence service extraction is by evaluating monolith suitability and mapping inter-service dependencies. A strategic extraction order is then designed to isolate bounded contexts progressively, preventing anti-patterns like distributed monoliths during the migration.

How do I design event contracts for inter-service communication?▼

Designing event contracts for inter-service communication involves defining schemas for events exchanged between newly extracted microservices. This decouples services by ensuring asynchronous communication rather than relying on tight synchronous dependencies within the original monolith.

Why does microservice decomposition create a distributed monolith?▼

Microservice decomposition creates a distributed monolith when bounded contexts are improperly separated, leaving tight inter-service dependencies. Avoiding this anti-pattern requires analyzing system dependencies and designing proper event contracts before sequencing extraction.

When do I need to analyze monolith suitability for microservices?▼

You need to analyze monolith suitability for microservices when considering migrating large applications. This evaluation determines if the system can be decomposed into bounded contexts and identifies the strategic extraction order required to prevent distributed monoliths.
