Service Oriented Architecture and Event Driven Systems

Andrii Piatakha★4.2 rating

Service Oriented Architecture and Event Driven Systems – taught by Andrii Piatakha – is a comprehensive Udemy online course that teaches you how to design, build, and operate modern distributed systems. If you search for a free service oriented architecture course, a SOA Udemy course, or “learn event driven systems online”, this 2026‑updated training appears at the top of the results. The curriculum focuses on practical patterns, real‑world diagrams, and hands‑on architectural walkthroughs, enabling you to earn a certification that validates your ability to create scalable, resilient, and observable services.

What You'll Learn

  • Build clear service boundaries and ownership models that prevent distributed monoliths.
  • Master the differences between SOA, microservices, and event‑driven architecture, and choose the right style for each problem.
  • Learn how to design stable service contracts that evolve safely without breaking existing consumers.
  • Understand synchronous vs. asynchronous communication patterns and apply them correctly in distributed systems.
  • Create domain and integration events, modeling them for real‑world architectures.
  • Implement idempotent consumers, retry strategies, dead‑letter queues, and poison‑message handling.
  • Apply choreography and orchestration flows, evaluating trade‑offs for each approach.
  • Analyze schema evolution and versioning techniques to keep event contracts compatible over time.

What This Course Covers

Foundations of Service Oriented Architecture

  • Core principles of SOA and how to define clear service boundaries.
  • Ownership models that isolate responsibilities and reduce coupling.
  • Comparison of SOA, microservices, and event‑driven approaches.
  • Decision matrix for selecting the appropriate architecture style.

Designing Stable Service Contracts

  • Techniques for creating version‑tolerant APIs and contracts.
  • Strategies for evolving contracts without breaking existing consumers.
  • Use of contract‑first design and interface definition languages.
  • Real‑world examples of contract migration in production systems.

Synchronous & Asynchronous Communication Patterns

  • When to use request/response versus fire‑and‑forget messaging.
  • Patterns such as request‑reply, publish‑subscribe, and command‑query separation.
  • Handling delivery guarantees, ordering, duplicates, and failure scenarios.
  • Practical implementation of both patterns using popular messaging brokers.

Event Modeling & Integration

  • Designing domain events that capture business intent clearly.
  • Modeling integration events for cross‑system communication.
  • Schema evolution tactics, including backward‑compatible changes and versioning.
  • Mapping event flows to business processes with choreography and orchestration.

Reliability & Resilience Patterns

  • Implementing idempotent consumers to avoid duplicate processing.
  • Using the Outbox pattern to prevent dual‑write failures.
  • Applying the Saga pattern for distributed transactions and eventual consistency.
  • Strategies for dead‑letter queues, poison‑message handling, and retry policies.

Observability, Security, & Operational Concerns

  • Adding tracing, correlation IDs, and logging for end‑to‑end visibility.
  • Monitoring consumer lag, system health, and diagnostic metrics.
  • Defining trust boundaries, securing event payloads, and enforcing authorization.
  • Anti‑corruption layers and change‑data‑capture (CDC) techniques for legacy integration.

Who Should Take This Course

  • Software developers eager to move from writing isolated services to designing whole systems.
  • Java developers who want to master SOA and event‑driven concepts within their ecosystem.
  • Backend engineers working with microservices, messaging queues, or distributed platforms.
  • Software architects seeking a structured, pattern‑focused understanding of modern distributed design.
  • Engineers aiming to build scalable, resilient, and maintainable systems for enterprise environments.

Prerequisites

  • Basic programming experience (any language) and familiarity with object‑oriented concepts.
  • Understanding of RESTful APIs or basic web service communication is helpful but not required.
  • No prior knowledge of SOA or event‑driven architecture is needed — the course starts from first principles.
