Microservice Design (with EventStorming, DDD)

If you want to learn the core of DDD for sure!

Microservices design
More flexible, more powerful.

What is important in order to independently deploy and change microservices in an MSA structure? It is to identify microservices that are functionally cohesive and have few dependencies on other services . In addition, the internal structure of microservices must be flexible to technological changes, allowing for agile response to business changes.

For this purpose, domain-driven design (DDD) techniques are mainly used for microservice design, and hexagonal architecture is mainly used for internal architecture. In this lecture, we will explain how to design microservices with a cohesive and flexible structure based on domain-driven design and hexagonal architecture.

2 Hottest Techniques in Microservices Design 🌳

Only for this lecture
Check out the features 📗

• The lecture is given in a raw voice, based on the experience of practitioners. 😁
• We aim for the ideal of microservices, but present an approach that reflects reality.
• This course consists of concepts and hands-on practice using online tools.
• We introduce hot field standards and judgment(?) techniques used in actual microservice design .

So, this is helpful for these people! 🏃‍♀️

Microservices Design 💻

Understanding the concept of domain driven design

Domain-Driven Design - Learn about several concepts of strategic design: domain models, subdomains, ubiquitous language, and bounded contexts.

The most practical microservice derivation technique: Event Storming

We will explain the Event Storming Workshop, the easiest and simplest microservice derivation technique.

Introduction to various microservice business logic implementation patterns

We'll explore several patterns for designing business logic inside microservices (transaction scripts, active records, domain models, etc.) and what choices to make.

Understand various internal architecture patterns for defining the internal structure of microservices.

Let's think about the desirable internal structure of microservices through comparison with the limitations of the traditional layered architecture and the features of the hexagonal and clean architectures.

Event Storming Workshop Practice

We will conduct an event storming workshop using the online tool Miro on the topic of book lending system.

Practice creating context mapping diagrams

Define relationships in the bounded context identified through event storming and define candidate microservices.

Domain Modeling Practice

Let's design the heart domain model of a microservice using the tactical design tools of domain-driven design.
