Master Microservices Architecture
Learn to build scalable, distributed systems using microservices architecture. Master design patterns, communication strategies, containerization, and deployment.
Microservices Fundamentals
Understand the core concepts and architecture of microservices
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
Architecture Comparison
Understand the differences between monolithic and microservices architecture
Monolithic Architecture
- Single unified codebase
- Tightly coupled components
- Scaled as a single unit
- Single database
- Simple deployment
- Single point of failure
Microservices Architecture
- Loosely coupled services
- Independent deployment
- Polyglot persistence
- Distributed system
- Fault isolation
- Complex deployment
Communication Patterns
Master different communication strategies in microservices
Synchronous Communication
Direct service-to-service calls using REST, gRPC, or GraphQL. Request/response pattern with immediate feedback.
Asynchronous Communication
Event-driven messaging using RabbitMQ, Kafka, or AWS SQS. Services communicate via events without direct coupling.
Advanced Microservices
Master advanced concepts and patterns
Communication in Microservices
- Synchronous (REST, gRPC)
- Asynchronous (RabbitMQ, Kafka)
- Request/response vs Event-driven
- Message formats (JSON, Protocol Buffers)
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
Data Management
Handle data in distributed microservices environment
Data Management Patterns
- Polyglot persistence
- Event sourcing
- CQRS pattern
- Distributed transactions (Saga)
Service Discovery
- Client-side discovery
- Server-side discovery
- Tools: Eureka, Consul
- Health checks
API Gateway
- Role of API gateway
- Authentication & security
- Rate limiting
- Tools: Zuul, Kong, Nginx
