From Monolith to Microservices: The Redistribution of Complexity

March 12, 2026 · 1830 words · 9 min

Microservices are often introduced with a deceptively simple narrative: monoliths become too complex, microservices make systems easier to manage, therefore system evolution naturally moves from monolith to microservices. The problem with this narrative is not that it is entirely wrong. The problem is that it hides the more important truth: microservices usually do not remove complexity. They redistribute it.

In a monolith, complexity is concentrated inside the codebase. It shows up as coupling between modules, risky deployments, a rigid technology stack, and increasing coordination costs inside one delivery unit. Microservices attempt to break that delivery unit apart so teams can evolve parts of the system independently. But once the split happens, complexity does not disappear. It moves from in-process calls, local transactions, and shared code into service boundaries, network uncertainty, data consistency, runtime governance, and organizational coordination.

Principles Of Microservice Architecture

The microservices architecture is a method of building complex applications as a collection of small services, where each service runs in its own independent process and is typically built around specific business capabilities. These services communicate through well-defined APIs, often HTTP RESTful APIs or lightweight messaging systems. When designing a microservices architecture, it is crucial to follow a series of core principles to ensure the maintainability, scalability, and flexibility of the system.
