๐ŸŽŸ๏ธ Real-Time Movie Ticketing Platform

This project was developed as part of the CJ OliveNetworks CloudWave 3rd Cohort Internship, aiming to provide a robust and scalable movie ticketing platform capable of handling high volumes of traffic during movie releases and special events.

๐ŸŒ Architecture Overview

image

The platform consists of three primary VPCs across two AWS regions:

  • Dev VPC (Seoul Region): Development environment and CI/CD setup
  • Prod VPC (Seoul Region): Production-grade services with auto-scaling and traffic management
  • DR VPC (Singapore Region): High availability disaster recovery (Hot Standby)

โš™๏ธ Key Features

โœ… CI/CD Pipeline

  • Automated build and security vulnerability scanning with GitHub Actions
  • Docker image push to Amazon ECR
  • GitOps-based automated deployments to Amazon EKS via ArgoCD
  • Automatic deployment triggered by changes in main and argocd branches

โœ… Scalability & Reliability

  • Containerized microservices deployed on Amazon EKS
  • Node-level auto-scaling with Karpenter
  • Pod-level auto-scaling via Horizontal Pod Autoscaler (HPA)
  • Cross-region Hot Standby disaster recovery setup in Singapore

โœ… Asynchronous & Concurrent Processing

  • Redis utilized for handling high concurrency reservation requests and preventing race conditions
  • RabbitMQ employed for asynchronous processing such as payment handling and email notifications

๐Ÿ’ธ Cost Optimization

  • Savings Plan to reduce EC2 instance costs by up to 49%
  • Deploying SonarQube on Spot Instances to reduce CI/CD costs by up to 70%
