Microservice Patterns with .NET Training in Madrid, Spain

This course introduces microservice architecture patterns and their practical implementation with .NET. Participants will explore the most common patterns for communication, data management, security, and reliability in microservices. The course blends conceptual learning with hands-on labs using .NET and related frameworks.

Microservices Foundations and Core Patterns

Module 1: Introduction to Microservice Patterns

• Monolith vs Microservices architecture
• Challenges addressed by patterns
• Pattern categories: decomposition, integration, data, observability, security

Module 2: Decomposition Patterns

• Decompose by business capability
• Decompose by subdomain (DDD and bounded context)
• Strangler Fig pattern for migrating monoliths

Module 3: Communication Patterns

• Synchronous vs Asynchronous communication
• API Gateway pattern in .NET with Ocelot
• Aggregator and Backend-for-Frontend (BFF) patterns

Module 4: Data Management Patterns

• Database-per-service pattern
• Saga pattern for distributed transactions
• CQRS (Command Query Responsibility Segregation)
• Event sourcing basics with .NET

Reliability, Security, and Observability

Module 5: Reliability Patterns

• Circuit Breaker pattern using Polly in .NET
• Retry and Timeout patterns
• Bulkhead pattern for resource isolation

Module 6: Security Patterns

• Centralized authentication and authorization
• JWT authentication in .NET microservices
• API Gateway security patterns (rate limiting, throttling)
• mTLS for service-to-service security

Module 7: Observability Patterns

• Health Check pattern in .NET (AspNetCore.Diagnostics.HealthChecks)
• Distributed logging with Serilog and ELK stack
• Monitoring with Prometheus and Grafana
• Distributed tracing with OpenTelemetry

Module 8: Wrap-up and Best Practices

• Review of microservice patterns covered
• When to apply (and when to avoid) specific patterns
• Best practices for microservices with .NET
• Final Q&A and roadmap for deeper learning
