Syllabus

Microservices Communications - The Basics

In this module, we will cover the core principles of microservices communication, focusing on key differences with monolithic systems. You will explore synchronous vs asynchronous communication and learn how to design and implement RESTful APIs for seamless service interaction.

Microservices Communication Patterns - API Gateways

In this module, we will dive into API Gateway patterns, exploring how they help manage and route traffic between microservices. You’ll design and implement the e-shop architecture using API Gateways, optimizing routing and communication for different client requirements.

Microservices Asynchronous Communication & Event-driven Architecture

In this module, we will introduce asynchronous communication and event-driven architecture (EDA), exploring how these patterns support scalability and resilience. You will design and implement a publish/subscribe model in the e-shop’s microservices to optimize communication and system performance.

Microservices Data Management - Choosing the Right Database

In this module, we will explore the principles and patterns of microservices data management, including how to choose the right database. You will learn about database-per-service, polyglot persistence, and scaling strategies like sharding to ensure data consistency and high performance in your microservices.

Microservices Data Management - Commands and Queries

In this module, we will discuss advanced microservices data management patterns like CQRS and event sourcing. You will learn how to separate commands and queries to improve performance and scalability, and design a system that ensures eventual consistency across distributed transactions.
