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 🙌
