Monolith, Modular Monolith & Microservices — Visually Explained

Monolith, modular monolith, and microservices—what changes when we keep an application's parts together or let them run separately? This animated explanation follows one online shop through all three approaches. See how code boundaries, deployment, data ownership, network failures, scaling, and teams affect the choice—and why a modular monolith can be the right long-term answer. No prior knowledge of software architecture needed.
