Microservice Architecture and Design Principles

Service boundaries, communication, data and operational trade-offs

Introduction

Why this course

Examine microservice design through theory, practical examples and case studies. Compare decomposition, communication, data management and operations to make informed architecture decisions. The two-day course is a design foundation rather than a promise of complete production implementation.

Learning outcomes

Compare microservices and monoliths and identify benefits and trade-offs.
Apply DDD concepts to proposed service boundaries and context maps.
Evaluate synchronous/asynchronous integration and data-consistency choices.
Outline security, observability, testing and CI/CD strategies.
Analyse case studies and recognise common implementation pitfalls.

Prerequisites

Basic understanding of software architecture concepts
Familiarity with web development and APIs
Knowledge of distributed systems and database concepts

Training outline

8 modules

01Session 1 — Architecture foundations4 topics

Understanding the basics of microservice architecture
Key characteristics and benefits of microservices
Contrasting microservices with monolithic architecture
Microservice ecosystem and components

02Session 2 — Decomposition and DDD4 topics

Identifying monolithic system challenges
Approaches to decomposing monolithic systems into microservices
Domain-driven design (DDD) principles
Defining service boundaries and context mapping

03Session 3 — Communication and integration4 topics

Communication patterns between microservices
Synchronous vs. asynchronous communication
Event-driven architecture and message queues
API gateways and service discovery

04Session 4 — Data management4 topics

Strategies for managing data in a microservice environment
Database per service vs. shared database
Event sourcing and CQRS (Command Query Responsibility Segregation)
Distributed data consistency and eventual consistency

Database ownership, CQRS and event sourcing are evaluated as design choices with operational costs; they are not mandatory for every service.

05Session 5 — Security and authentication4 topics

Common security challenges in microservices
Authentication and authorization strategies
Implementing secure communication between services
Best practices for securing microservices

06Session 6 — Monitoring and logging4 topics

Importance of monitoring and logging in microservices
Monitoring key performance indicators (KPIs) and metrics
Distributed tracing and logging techniques
Using monitoring tools and platforms

07Session 7 — Testing and delivery4 topics

Strategies for testing microservices
Unit testing vs. integration testing
Implementing CI/CD pipelines for microservices
Blue-green deployments and canary releases

08Session 8 — Case studies and review4 topics

Real-world case studies of successful microservice implementations
Lessons learned and best practices from industry examples
Challenges and pitfalls to avoid
Q&A session and closing remarks
