Fully Automated Application Deployment CI/CD Pipeline using CircleCi

This project is meant to implement a complete CICD pipeline to start once there is a push to the master branch. The pipeline is nearly 12 jobs running on the code to make sure it is bug-free and reliable before deployment.

The final output in bullet points:

• Deploy Infrastructure using AWS CLI commands and CloudFromation Templates.
• Configure the provisioned backend EC2 instance using Ansible Playbooks and Roles.
• Migrate the Database to an RDS-Postgres database on AWS and integrate it into the provisioned EC2.
• Deploy application Frontend UI and host it on AWS S3 as a static website.
• Deploy application Backend Code on EC2 and open PM2 server on port 3030 using Ansible.
• Smoke Test the whole deployment process to ensure the application is working as intended.
• Promote the application on CloudFront CDN utilizing (Blue/Green) Deployment Strategy.
