Overview

This repository showcases the transformation of an e-commerce platform from a monolithic architecture to a microservices-based architecture using the MERN stack. The application was initially built as a single, unified codebase and has now been divided into four distinct, scalable microservices, each encapsulated in Docker and orchestrated using Kubernetes. This enhances scalability, maintainability, and deployment flexibility.

Microservices Description

Frontend Service

Manages the user interface and interaction.

User Service (user)

Handles user authentication and profile management.

Product Service (product)

Manages product inventory, descriptions, and details.

Order Service (cart_order)

Processes and tracks orders.

Technologies Used

• CI/CD: For continuous integration and continuous deployment, enhancing the software delivery process.
• MongoDB: Database for storing all application data.
• Express.js: Backend framework used within Node.js.
• React.js: Library for building the user interface.
• Node.js: JavaScript runtime for executing the backend in JavaScript.
• Docker: For containerizing each microservice.
• Kubernetes: For automating deployment, scaling, and operations of application containers.

Getting Started

Follow these instructions to get a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• Docker
• Kubernetes (e.g., Minikube, Docker Desktop)
• Node.js and npm

Installation

1. Clone the repository

   https://github.com/akash47angadi/Monolithic_to_microservice.git
   cd Monolithic_to_microservice

2. Build Docker Images

   cd frontend
   docker build -t yourdockerhubusername/frontend:latest .
   cd ../user
   docker build -t yourdockerhubusername/uc1:latest .
   cd ../product
   docker build -t yourdockerhubusername/uc2:latest .
   cd ../cart_order
   docker build -t yourdockerhubusername/uc3:latest .

3. Deploy with Kubernetes

   kubectl apply -f kubernetes.yaml

4. Access the Application

   kubectl get svc

   Note the external IP and port to access the frontend service.
