Design Microservices Architecture with Patterns & Principles

This course is will be the journey of software architecture design with step by step evolving architecture from monolithic to event driven microservices.

We will start the basics of software architecture with designing e-commerce Monolithic architecture that handles low amount of requests.

After that step by step evolves the architecture with;

• Layered Architecture

• Clean Architecture

• Modular Monolithic Architecture

• Microservices

• Event-Driven Microservices Architectures

• and lastly Serverless Microservices Architectures with designing together that handle millions of requests. This is a step-by-step process for software system design and evolve from monolithic to microservices following the patterns & principles.

We will discuss microservices architectures with all aspects,

• Microservices Decomposition

• Microservices Communications (Sync / Async Message-Based Communication, API Gateways)

• Microservices Data Management (Databases / Query / Commands)

• Microservices Transaction Management

• Microservices Distributed Caching

• Microservices Deployments with Containers and Orchestrators

• Microservices Resilience

with applying microservices design patterns and practices.

We are going to design with together and step by step with refactor architectures with all aspects of microservices pillars.

We will start with designing Monolithic Architecture. And you can see that we have Functional and Non-functional requirements that should cover our design and we have patterns and principles toolbox that we will learn and use these principles when evolving architectures.

Way of Learning — The Course Flow

We will always starts with the problem and try to solve this problem with learning and designing new architectures, patterns and best practices.

• Problem -> Learn -> Design -> Adapt -> Evaluate

We will complete this circle for every section of the course. You will find that we will add new requirements in order to handle millions of request and learn new patterns and practices that will use these principles when evolving architectures.

You will find that we will add new requirements in order to handle millions of request and learn new patterns and practices that will use these principles when evolving architectures.

We will see full of patterns and principle toolbox is loading with new patterns and apply them into current designs. We will see latest patterns that we use more than 30 patterns and practices with implementing high scalability, high availability and handle millions of request requirements.

Let me write some microservices pattern which we covered in this course:

• The Database-per-Service Pattern

• API Gateway Pattern, Gateway Routing/Aggregation/Offloading Pattern

• Backends for Frontends pattern BFF

• Service Aggregator Pattern, Service Registry/Discovery Pattern

• Fan-out Publish/Subscribe Messaging Pattern

• Topic-Queue Chaining & Load Balancing Pattern

• The Shared Database Anti-Pattern and Polyglot Persistence

• Database Sharding Pattern, CAP Theorem

• Materialized View Pattern

• CQRS and Event Sourcing Patterns

• SAGA Pattern — Choreography-based/Orchestration-based SAGA

• Compensating Transaction Pattern

• Transactional Outbox Pattern

• Dual Write Problem

• CDC — Change Data Capture with Outbox Pattern

• Event Hubs and Real-time Event Streaming in Event-Driven Microservices Architecture

• Cache-Aside Pattern for Microservices Distributed Caching

• Sidecar Pattern

• Service Mesh Pattern

• DevOps and CI/CD Pipelines for Microservices Deployments

• Deployment Strategies for Microservices: Blue-green, Rolling and Canary deployments

• Infrastructure as Code (IaC) and usage in Microservices Deployments

• Microservices Resilience, Observability and Monitoring Patterns

• Retry and Circuit Breaker Patterns

• Bulkhead / Timeout / Cache / Fallback Patterns

• Elastic Stack for Microservices Observability with Distributed Logging

• Microservices Health Checks: Liveness, Readiness and Performance Checks

• Serverless Microservices Architecture implementation on AWS

So the course flow will be the both theoretical and practical information:

• We will always start with a business problem

• We will learn a specific pattern, why and where we should use

• After that we will see the Reference architectures that applied these patterns

• After that we will design our architecture with applying this newly learned pattern with together

• And lastly we will decide which Technologies can be choices for that architectures.

And at the last section, we will made Code Review for Existing Microservices Architecture Repository on GitHub for practical implementation of microservices architecture.

So this course will includes:

• Hands-on Design Activities

• Iterate Design Architecture from On-Premises to Cloud Server-less architectures

• Evolves architecture monolithic to Event-Driven Microservices Architectures

• Refactoring System Design for handling million of requests

• Apply best practices with microservices design patterns and principles

• Examine microservices patterns with all aspects like Communications, Data Management, Caching and Deployments

• Prepare for Software Architecture Interviews

• Prepare for System Design Architecture Interview exams.

I have been joined several famous company's architecture position interviews, also involved software architect positions assessment process more than 50+ interviews collect the architecture requirements for software industry positions.

So with this course, you will gain real-world experience about all architecture positions from monolithic to event-driven microservices architectures.

This course prepared for the beginner but at least you should familiar with basics of software architectures. This course will have good theoretical information but also will be 90% of hands-on design activities. All course architecture steps will designed step by step and together.

I hope you'll join me on this journey and develop this project with me.
