Description
Modern software systems are no longer single applications. They are ecosystems of services, events, integrations, and distributed workflows. Building such systems requires much more than writing code. It requires architectural thinking.
This course is designed to teach you how real distributed systems are designed, using Service Oriented Architecture and Event Driven Architecture as the foundation. Instead of focusing on theory alone, we will explore the architectural principles, patterns, and design decisions used in modern scalable systems.
You will learn how to think like an architect and understand why certain design choices succeed while others lead to fragile distributed systems.
Throughout the course we will move step by step from the fundamentals of service design to advanced patterns used in production architectures.
In this course you will learn how to:
• Design clear service boundaries and ownership models that prevent distributed monoliths
• Build systems using Service Oriented Architecture principles that scale over time
• Understand when to use synchronous communication and when event driven systems are the right choice
• Design domain events and integration events correctly
• Apply event driven architecture patterns used in real production systems
But this course goes far beyond basic architecture concepts.
You will also explore the hard problems of distributed systems that many courses ignore.
You will learn how to:
• Handle message delivery guarantees, retries, and failure scenarios
• Design idempotent consumers and resilient messaging flows
• Use event choreography and orchestration to model business processes
• Manage event schema evolution and versioning without breaking consumers
• Implement eventual consistency and Saga patterns for distributed transactions
We will also cover essential reliability patterns used in production systems.
You will learn:
• Why dual write breaks systems and how the Outbox pattern solves it
• How to integrate legacy systems using Anti Corruption Layers and CDC approaches
• How to detect and avoid dangerous architectural anti patterns
In addition, we will explore the operational side of distributed systems, which is often overlooked but absolutely critical.
You will understand:
• How to design systems that are observable and debuggable
• How to trace asynchronous flows across multiple services
• How to monitor event consumers, lag, and system health
Security is another major topic in this course.
You will learn how to design secure event driven systems by:
• Defining trust boundaries between services
• Preventing sensitive data leaks in events
• Applying the secure lookup pattern for protected information
To make these concepts concrete, the course includes practical diagrams, architectural walkthroughs, and code examples that demonstrate how these patterns work in real systems.
By the end of this course, you will understand how modern distributed architectures actually work and how to design systems that are:
• Scalable
• Resilient
• Observable
• Secure
• Maintainable over time
If you are a developer who wants to move beyond writing individual services and start designing entire systems, this course will give you the architectural mindset and practical knowledge needed to do exactly that.
Who this course is for:
- Software developers who want to understand how modern distributed systems are designed
- Java developers interested in learning Service Oriented and Event Driven Architecture principles
- Backend engineers working with microservices, messaging systems, or distributed platforms
- Software architects who want a structured understanding of SOA and event driven design
- Developers who want to move from coding individual services to designing whole systems
- Engineers who want to understand real world integration patterns and messaging architectures
- Anyone interested in building scalable, resilient, and maintainable distributed systems
