Event Sourcing Explained: A Deep Dive into System Architecture & Microservices

Description

In this detailed tutorial, we unpack the architecture behind the Event Sourcing pattern — how storing immutable events instead of just current state unlocks auditability, state-replay, and flexibility in your system design. You’ll learn about key components like the event store, event streams, aggregates, projections and how they interact in both monoliths and microservices. We’ll compare with the related patterns like CQRS (Command Query Responsibility Segregation) and show how event-sourced architectures differ from plain event-driven design. Whether you’re designing a fintech ledger, audit-driven workflow, or scalable microservice system, this deep dive will give you the architecture roadmap, trade-offs, and implementation strategies you need.
