The app is deployed behind an **Application Load Balancer (ALB)** for high availability and scalability. This solution ensures continuous integration and delivery (CI/CD), secure deployment processes, and scalability, meeting modern DevOps best practices.\n\n## Technologies Used\n- **MERN Stack** (MongoDB, Express, React, Node.js)\n- **GitLab CI/CD** for automation\n- **AWS EC2** for hosting the application\n- **AWS Application Load Balancer (ALB)** for traffic distribution\n- **Docker** for containerization\n- **AWS Route 53** for DNS management\n- **SSL/TLS Encryption** for secure connections\n\n## Features\n- **Continuous Deployment (CD)** with GitLab CI\n- **Scalable and fault-tolerant architecture** using EC2 and ALB\n- **Secure deployment** with SSL/TLS and load balancing\n- **Dockerized MERN app** for environment consistency\n\n## Architecture\n\n1. **GitLab CI**:\n   - The application is hosted in a GitLab repository. Each commit triggers the pipeline for automated testing, building, and deployment.\n   \n2. **AWS EC2**:\n   - After the application is built, it is deployed to an AWS EC2 instance using Docker containers.\n   \n3. **AWS ALB (Application Load Balancer)**:\n   - An ALB is used to distribute incoming traffic across multiple EC2 instances for high availability.\n \n\n \n\n## How to Star the Repository\nIf you find this project helpful, please star the repository on GitHub to show your support:\n1.
