Building Scalable Microservices with Node.js and Docker

Microservices Architecture Fundamentals

Microservices have become the standard for building large-scale, maintainable applications. However, implementing them correctly requires careful planning and the right tools.

Key Components

Service Discovery

Implementing robust service discovery is crucial for microservices communication. We'll explore patterns using Consul and Eureka.

API Gateway

Learn how to implement an API gateway using Node.js and Express to handle routing, authentication, and rate limiting.

Containerization with Docker

Docker provides the perfect environment for microservices. We'll cover multi-stage builds, container orchestration, and best practices.

Real-World Implementation

Our experience at MoonTech has taught us several valuable lessons about microservices:

• Start with a monolith and extract services gradually
• Implement comprehensive monitoring from day one
• Use contract testing to ensure service compatibility
• Plan for failure with circuit breakers and retry mechanisms
