DDD-based MSA: Event Storming Design & Microservices Pattern

This introduces explanations of microservice architecture and the advantages of microservice architecture over traditional monolithic architecture in responding to client needs.

It provides methods for designing DDD (Domain-Driven Design), which is customer-driven design at the core of microservice architecture, through event storming.

At this time, based on client requirements scenarios, event storming design practice is conducted to explain the purpose definition for each sticker and introduce how to proceed with design arrangement.

This explains event storming by dividing it into two phases: the strategic phase, which designs events (results of state changes), commands (that cause state changes), actors (subjects of actions), policies (reactions to events), read models (data that assists decision-making), aggregates (data storage), and bounded contexts (expressing limited contexts); and the tactical phase, which focuses on designing aggregate attributes, configuring command methods, and setting event triggers and attributes.

In the implementation phase, starting with understanding event storming model-based code generation, it explains fundamental theories about various microservice patterns such as Gateway, CQRS, Pub/Sub, Keycloak, and more, and provides an environment where you can actually practice these concepts.

Following the completion of all microservice pattern learning, the course covers the deployment and operations section, focusing on the essential steps for cluster deployment: packaging, dockerization, and cluster deployment. Students will learn the process of creating images using Dockerfile and the subsequent deployment procedures
