Design Pattern, Architecture and Microservices - Free Session
What You'll Discover in This Introduction Session:
→ Why most developers misunderstand Design Patterns (and how to think like an architect instead)
→ The connection between Abstraction and Decoupling that changes how you approach every problem
→ How SOLID principles actually work in production code (not toy examples)
→ The real difference between Strategic DDD and Tactical DDD (and why one matters more than you think)
→ Why microservices fail (and how proper bounded contexts prevent the disaster)
→ The brutal truth about moving from Monolith to Microservices
What This Training Covers (Full Syllabus):
Module 1: Foundational Thinking
OOP, SOLID, DI, IOC from an Architect's perspective
Understanding Abstraction, Encapsulation, and Decoupling
Design Patterns vs Architecture Patterns vs Architecture Style
Interfaces vs Abstract Classes (when to use what)
Aggregation, Composition, Association relationships
Module 2: Core Design Patterns (The GOF Way)
Singleton, Factory, Adapter, Bridge, Composite, Decorator
Template, Strategy, Façade, Memento, Flyweight patterns
UML: Class Diagrams, Sequence Diagrams, Use Cases
Individual learning vs DDD-driven learning
Module 3: Strategic DDD & Microservices Architecture
Domain-Driven Design fundamentals
Subdomains: Core, Supporting, Generic
Bounded Context (the logical boundary)
Context Maps and the 9 Context Map Patterns
Understanding Upstream/Downstream relationships
When to break monoliths (and when not to)
Module 4: Tactical DDD Implementation
Entity, Value Objects, and Service Objects (the right way)
Aggregate Roots and transactional boundaries
Repository pattern in DDD context
Anemic vs Rich Domain Models
Factory pattern in DDD vs GOF
Module 5: CQRS & Event Sourcing

Module 6: Persisting DDD with EF Core
Value Objects mapping (Owned Objects)
Multiple DB Contexts: OLTP (Entities) + Audits (Events)
Soft deletes and child entity management
EF mapping vs Aggregate root purity
Constructor-based property passing
Module 7: Microservices Communication

Short-lived vs Long-lived failures
Circuit breaker states: Break, Reset, Half-Open
Module 9: API Gateway & Service Discovery
Why API Gateway pattern matters
Ocelot implementation
Rate limiting strategies
Health monitoring with Consul
Module 10: Transactions in Distributed Systems
Why classical transactions don't work
Saga pattern: Choreography vs Orchestration
Compensating transactions
Transactional Outbox pattern
Strong vs Casual vs Eventual Consistency
Module 11: Authentication & Authorization
OpenID vs OAuth vs OpenID Connect
JWT implementation across microservices
API Gateway approach vs Individual service approach
Module 12: Moving to Production
Integrating everything in ASP.NET MVC
Deployment considerations
Microfrontend patterns
Architecture Styles Covered:
Onion Architecture (Domain-Oriented)
Clean Architecture (Use Case-Oriented)
Hexagonal Architecture (Ports & Adapters)
Who Should Attend This Introduction Session:
→ Senior developers stuck at ₹15-22 lakhs wondering why that architect role isn't happening
→ Tech leads who inherit architectural messes and don't know how to fix them
→ Anyone who's built applications that "work" but can't scale or maintain
→ Developers moving from service companies to product companies who suddenly need architectural skills
→ Engineers preparing for system design interviews at product-based companies
Who This Is NOT For:
→ Complete beginners (you need solid OOP and .NET fundamentals first)
→ Developers looking for quick shortcuts (architecture requires deep understanding)
→ Anyone expecting to "master microservices" in one session (this is an introduction; the real work comes in the full course)
