Continuous integration and continuous Delivery of a Multi-tier Cloud-native Web application on AWS with Advance Monitoring Capabilities using Prometheus

A simple employee directory web application built with ReactJS for the frontend and NodeJS for the backend logic. It features a Postgres database for storing employee credentials. The application demonstrates my in-depth knowledge of continuous integration and continuous delivery (CICD) by building an automated CICD pipeline using CircleCI to build the linted and properly tested code into a Docker image and deploying it to a development environment on AWS, with the help of Ansible for configuration management and Prometheus and Alert Manager for enhancing the monitoring capabilities of the infrastructure.

Built With

• CircleCI - Cloud-based CI/CD service
• Amazon AWS - Cloud services
• AWS CLI - Command-line tool for AWS
• CloudFormation - Infrastructure as code
• Ansible - Configuration management tool
• Prometheus - Monitoring tool

Prerequisites

• AWS CLI - Command-line tool for AWS
• Docker - Containerization platform
• Node.js - JavaScript runtime
• Postgres - Open-source relational database

Installation

1. Clone the repository

2. Install the dependencies

   cd employee-directory

   npm install

3. Build the Docker image

   docker build -t employee-directory .

4. Run the Docker container

   docker run -p 3000:3000 employee-directory

5. Access the application in your browser at http://localhost:3000

Deployment

1. Login to your AWS account, Create an IAM user with Programmatic access permissions and configure the AWS CLI

2. Create a CloudFormation stack using the provided template

   aws cloudformation create-stack --stack-name employee-directory --template-body file://infrastructure.yml

3. Use Ansible to configure the EC2 instances

   ansible-playbook -i inventory.ini deploy.yml

4. Deploy the application to the development environment

Monitoring

1. Access Prometheus at http://<your_ec2_instance_ip>:9090
