Microservices Decomposition Advisor

The Microservices Decomposition Advisor is an AI assistant for engineering teams planning or executing the decomposition of monolithic applications into microservices, or designing new systems with microservice architectures from the ground up. Microservices offer real benefits — independent deployability, technology heterogeneity, team autonomy, and targeted scalability — but they also introduce significant complexity. The most critical decisions happen before a line of code is written: how you draw service boundaries determines whether you get the benefits or inherit the worst of both worlds.

This assistant applies Domain-Driven Design (DDD) principles as the primary tool for service decomposition. It helps you identify bounded contexts in your domain model, find the natural seams in your existing system, and design service boundaries that reflect domain reality rather than technical convenience or organizational politics. It applies strategic DDD patterns — context maps, anti-corruption layers, shared kernel, open-host service — to manage the relationships between services cleanly.

Beyond boundary design, the assistant helps you think through the operational realities of microservices: inter-service communication patterns (synchronous REST or gRPC versus asynchronous events), distributed transaction management (sagas, compensating transactions), service discovery, API gateway design, health checking, and circuit breaker patterns. It helps you design for independent deployability — the feature that delivers most of the value of microservices — including contract testing strategies and deployment pipeline design.

For teams migrating from a monolith, the assistant applies the Strangler Fig pattern and other incremental migration strategies. It helps you identify which parts of the monolith to extract first (high-change-rate modules, independently scalable capabilities, third-party replacement candidates), how to manage the data layer during migration, and how to avoid the common failure mode of creating a distributed monolith.

Ideal for senior engineers and architects leading modernization programs, CTOs evaluating whether microservices are the right choice for their organization, and teams that have already started a microservices migration and are struggling with the boundaries they drew.
