Introduction to Microservices
- What are microservices?
- Monolithic vs Microservices architecture
- Benefits & challenges
- Real-world use cases
Core Principles
- Single Responsibility Principle
- Decentralized governance
- Independent deployment
- Continuous delivery
- Failure isolation
Architecture Components
- API gateway
- Service registry & discovery
- Load balancing
- Configuration server
- Messaging & event bus
Communication Patterns
- Synchronous (REST, gRPC)
- Asynchronous (RabbitMQ, Kafka)
- Request/response vs Event-driven
- Message queue patterns
Designing Microservices
- Domain-driven design (DDD)
- Bounded contexts
- Database per service
- Stateless services
Building Microservices
- RESTful API design
- Lightweight frameworks
- Spring Boot, Node.js, Flask
- Best coding practices
Architecture Comparison
Understand the evolution from monolithic to microservices
Monolithic Architecture
- Single unified codebase
- Tightly coupled components
- Scaled as a single unit
- Single database dependency
- Simple deployment process
- Single point of failure
Microservices Architecture
- Loosely coupled services
- Independent deployment
- Polyglot persistence
- Distributed system design
- Fault isolation
- Complex deployment
Data Management
- Polyglot persistence
- Event sourcing
- CQRS pattern
- Saga pattern for distributed transactions
Service Discovery
- Client-side discovery
- Server-side discovery
- Tools: Eureka, Consul, Zookeeper
- Service registry patterns
API Gateway
- Role of API gateway
- Authentication & security
- Rate limiting
- Tools: Zuul, Kong, Nginx
Microservices Security
- OAuth2 implementation
- JWT tokens
- Role-based access control
- Secure communication (HTTPS, TLS)
Monitoring & Logging
- Centralized logging
- Distributed tracing
- Tools: ELK stack, Prometheus
- Grafana, Zipkin
Containerization & Deployment
- Docker basics
- Creating Docker images
- Kubernetes fundamentals
- CI/CD pipeline setup
Communication Patterns
Master synchronous and asynchronous communication strategies
Synchronous Communication
Direct service-to-service calls using REST APIs or gRPC. Request waits for response.
Best for: Real-time operations, simple workflows
Asynchronous Communication
Event-driven messaging with message brokers like Kafka or RabbitMQ.
Best for: Decoupled services, high throughput
