  • Provisioned EC2 instances for backend hosting and RDS MySQL for database management.
  • Configured Nginx as a reverse proxy to route external traffic to the Node.js application.
  • Troubleshot and resolved real-world deployment issues including database connectivity and server configuration errors.
  • Implemented a secure and scalable architecture to ensure high availability and performance.

Azure Three-Tier Architecture with Load Balancer

Azure | Virtual Network | Subnets | Load Balancer | Linux VM | Nginx

  • Designed and implemented a highly available three-tier architecture on Microsoft Azure.
  • Configured Virtual Network (VNet) with public and private subnets for proper resource isolation.
  • Deployed Linux virtual machines and configured Nginx for web application hosting.
  • Implemented Azure Load Balancer to distribute traffic and ensure high availability.
  • Configured Network Security Groups (NSG) to enforce secure access and control inbound/outbound traffic.
  • Tested and validated application accessibility through the load balancer endpoint.
