# Architecting the Future of Music: How I Helped 4 Elements Music's Platform Hit the Right Notes

## 🏢ABOUT THE COMPANY

[4 Elements Music](https://4elementsmusic.com/), an innovative music platform revolutionizing the digital music landscape through a new online music library, hired me via Toptal to design and implement the infrastructure to run the new version of their platform developed using Python/Django.

By leveraging AWS ECS Fargate, Infrastructure as Code (IaC), CI/CD pipelines on GitHub Actions integrated with AWS CodeDeploy, 4 Elements Music established a solid foundation for their new platform, improved operational efficiency by establishing a standard software delivery workflow, which accelerated the release cycle.

## ⛰ CHALLENGES

4 Elements Music wanted to replace a legacy system developed with Ruby on Rails with a modern, scalable, and resilient technological solution to enhance the user experience for music enthusiasts worldwide.

Their main application ran on a unique EC2 instance, which the full-stack developer manually deployed.

The client needed a network implementation following best practices and faced performance issues due to the old architecture.

## ✅ SOLUTION

The partnership with 4 Elements Music had two main goals:

* Containerization of a Python/Django monolith application to run on AWS ECS Fargate
    
* Implementation of a new platform to run containerized applications
    

After the discovery and assessment phase of the project, I crafted the following architecture to meet the client's needs:

To transform this architecture into reality, I performed the following tasks:

* Developed a new Dockerfile with multistage build to properly build the image. Hence, it runs on ECS safely and improves the existing Docker Compose file to help developers create a development environment similar to the new production environment.
    
* Created Terraform modules from scratch and published them in Terraform Cloud to implement a new platform using these tools.
    
* Designed and deployed a new VPC networking with three subnet tiers: public, private, and database subnets and attached a few VPC endpoints to establish private communication between the containers running on the VPC and some AWS services such as S3, ECR, Systems Manager, CloudWatch and OpenSearch.
    
* Deployed new storage instances: S3, RDS (PostgreSQL), and OpenSearch and helped during the data migration for the latest storage solutions.
    
* Deployed a GitHub Actions CI/CD pipeline to automate software delivery (test, build, and deploy applications using Blue/Green as release model) on top of ECS Fargate.
    
* Deployed CloudFlare to protect their API from bots and other basic attacks. It included migrating the [4elementsmusic.com](http://4elementsmusic.com) zone from Route53 to CloudFlare.
    
* Tracked work progress through GitHub Projects and maintained regular communication through Slack about the project status, constantly exposing progress, problems, and plans.
    

## 🏆 OUTCOMES

* Improved operational efficiency by adopting CI/CD pipelines to release software faster and securely.
    
* Established solid foundations for the new platform used during the product launch.
    
* Improved the platform's security by ensuring all new infrastructure resources adhered to best practices, including the "principle of least privilege."
    
* Finally, I meticulously documented all the new infrastructure using clear diagrams, ensuring a comprehensive understanding of the platform and facilitating its smooth operation for anyone in charge of its maintenance.
