VPC & IAM Security Lab
Transform TaskFlow into an enterprise-grade secure cloud application! Design custom VPC network architecture with public/private subnet isolation, configure advanced routing with Internet Gateway and NAT, implement multi-tier security zones (frontend in public, database in private), create fine-grained IAM policies, and test security controls. Master production AWS security patterns used by platform engineers in 2025.
Lab Overview
Design and implement production-grade AWS network architecture and security using VPC and IAM. Create custom VPC with public and private subnets, configure routing with Internet Gateway and NAT Gateway, implement security zones for multi-tier applications, design IAM roles and policies following least-privilege principles, and test security policies comprehensively.
