Modular Monolith Architecture & Microservices Reversal
A Modular Monolith is a single-deployable application architecture structured into logically independent bounded contexts using Domain-Driven Design (DDD). It achieves the operational simplicity and zero-latency RAM data passing of monolithic software while preserving clean module isolation, enabling organizations to eliminate microservices network overhead and cut AWS egress costs by up to 90% without sacrificing architectural flexibility. System Architecture Overview Answer-first: Modular Monolith architecture encapsulates distinct bounded contexts (e.g., Billing, Inventory, Orders) into a single Go binary process space, isolating domain data across PostgreSQL schemas while replacing external gRPC network hops with zero-allocation in-memory event channels. ...
