🏗️ Architecture Overview

1️⃣ API Gateway with YARP Reverse Proxy

• Implements Gateway Routing Pattern & Backend-for-Frontend (BFF) Pattern
• Rate Limiting ensures fair resource allocation
• Centralized Authentication, Authorization & Logging

2️⃣ Event-Driven Communication & Messaging

• Uses RabbitMQ & MassTransit for seamless messaging
• Implements AMQP, Publish/Subscribe, Saga Pattern, and Outbox Pattern
• Ensures Reliable & Decoupled Communication between services

3️⃣ Minimal APIs & Vertical Slice Architecture

• Implements CQRS, MediatR, and Marten Document DB (PostgreSQL)
• Uses Carter & Mapster for high-performance routing and DTO mapping
• FluentValidation ensures robust data validation

4️⃣ Redis-Powered Caching Service

• Implements Cache-aside Pattern for optimized caching
• Uses Redis Distributed Cache to store frequently accessed data
• Applies Decorator & Repository Patterns for extensibility

5️⃣ gRPC-Based High-Performance Microservice

• Uses gRPC for fast, efficient inter-service communication
• Built with SQLite & Entity Framework Core
• Implements FluentValidation & Mapster for DTO transformations

6️⃣ DDD & Clean Architecture Microservice

• Implements Domain-Driven Design (DDD), CQRS, and Event Sourcing
• Uses Entity Framework Core & SQL Server
• Encapsulates business logic with a Rich Domain Model
• Utilizes Interceptors for cross-cutting concerns

7️⃣ Shopping Web Client - ASP.NET Razor Pages

• Uses Refit-powered HttpClientFactory for seamless API communication
• Built with Bootstrap 4 & ASP.NET Core Razor Pages
• Implements View Components, Tag Helpers, and Model Bindings

8️⃣ Centralized Building Blocks

• Logging & Validation Behavior standardizes error handling
• Custom Exception Handling ensures consistent API responses
• Logical CQRS Implementation across services
