# Microservices Fundamentals Complete Guide

**[Medium](https://daily.dev/sources/medium_js)** · 11 min read · 47 upvotes · 2 comments

## Summary

A foundational guide to microservices architecture covering the monolith vs microservices decision, modular monoliths, and service communication patterns. Explains the defining characteristics of microservices (bounded contexts, independent deployability, decentralized data ownership, failure isolation), when each architecture is appropriate, the distributed monolith failure mode, and the tradeoffs between synchronous and asynchronous communication. Also introduces the CAP theorem as a foundational concept for distributed data patterns. Part 1 of a series focused on Java and Spring Boot.
