What are Microservices?

Microservices ek architecture style hai

Jisme application ko chote-chote independent services me divide kiya jata hai

Har service apna kaam karti hai

Har service independent hoti hai — iska apna DB ho sakta hai, apni logic, apna deployment

Agar ek service fail ho jaye → baaki application disturb nahi hoti

Example:

Ecommerce Application ke parts:
✔ Product Service
✔ Order Service
✔ Payment Service
✔ User Service

Yeh sab ek-dusre se independent hoti hain.

Why use Microservices?

Easy to Scale

Fast Deployment

Better Performance

Independent Codebase

Technology freedom (ek service Spring Boot me, dusri Node.js me)

Fault isolation

Types of Microservices 

1️⃣ Functional Microservices
2️⃣ Infrastructure Microservices
3️⃣ Database-driven Microservices
4️⃣ API Gateway Based Microservices
5️⃣ Event-Driven Microservices (Kafka/RabbitMQ)

Spring MVC vs Spring Boot in Microservices

 Spring MVC

Traditional Spring framework

More XML/Java configuration required

Microservices banana possible hai but heavy setup

 Spring Boot

Lightweight

Auto-configuration

Built for REST APIs

Microservices ke liye perfect

Embedded server (Tomcat included)

Plug-and-play architecture

Conclusion:
Microservices ke liye Spring Boot best choice hai.

Spring Boot Microservice Architecture

A microservice typically contains:

Controller Layer

Service Layer

Repository Layer

Database (MySQL/MongoDB etc.)

API endpoints

Application.yml application configs

Example Flow:

Request → Controller → Service → Repo → Database → Response

Microservice Communication 

Microservices ek-dusre se communicate karte hain:

✔ REST API
✔ Feign Client
✔ Eureka Server (Service Discovery)
✔ API Gateway (Routing)
✔ Message Queue (Kafka/RabbitMQ)

Deployment of Microservices

Microservices ko deploy kiya jata hai:

Docker Containers

Kubernetes (K8s)

AWS, GCP, Azure

Jenkins CI/CD pipeline
