Cloud & Infrastructure Challenges
Cloud & Infrastructure challenges put you in charge of the foundations every service runs on. You'll work through Cloud Computing fundamentals on AWS or Azure, provision environments with Terraform, control access with Cloud IAM, and ship workloads via Helm + Kubernetes deployments.
From there you'll handle the harder edges — Multi-cloud architecture, Landing zones, Advanced IaC modules, FinOps & cost optimization, and the AWS Well-Architected Framework — designing infrastructure the way platform teams actually scale it. Each challenge you solve earns a verified credential you can share with recruiters.
