🚀 Learning Progress – 3-Tier Application Project

Today, I made solid progress on my 3-Tier Application project using multiple DevOps & Cloud tools.

This project is pushing me to think beyond just writing code — especially while deploying a containerized backend.

These challenges are teaching me how production scenarios differ from local setups.

🔧 Tech Stack Used:

Terraform → Infrastructure provisioning (S3, CloudFront, networking)

Docker & Docker Compose → Containerization & multi-service setup

Backend Dockerized → Pushed to ECR → Deployed on ECS with ALB

Postman → API testing & validation

🎯 Key Learnings:

Understanding CI/CD vs Local environment differences

Writing infrastructure code with Terraform for real-world scenarios

Deploying backend containers on ECS and connecting via ALB

Preparing the foundation of a complete 3-Tier Application (Frontend + Backend + Database)

🔜 Next Steps:

⚡ CI/CD integration (Jenkins)

⚡ Deployment automation

⚡ Adding monitoring and scalability

I’m truly enjoying this journey of becoming a Cloud/DevOps Engineer 🙌
