☁️ My AWS Journey

Over the past months I’ve been exploring AWS and deploying real applications in the cloud.
Some of the highlights include:

  • 🖥 EC2 → launched and configured environments
  • 🐳 ECS & ECR → containerized and deployed Spring Boot apps
  • 🔐 Security Groups → fine-grained inbound/outbound rules
  • 📦 S3 + CloudFront → hosting static content with CDN
  • 🔑 IAM → least-privilege access control
  • 📊 CloudWatch → logs and metrics monitoring
📖 Read more about my AWS learning path

I started from simple EC2 setups, then moved into containerization with ECS/ECR,
and finally focused on security & monitoring with IAM and CloudWatch.
Currently, I am learning more about cost optimization and cloud-native architectures.
