What can you build with AWS Network Firewall?

AWS Network Firewall is a Cloud API. Developers commonly use cloud APIs for:

  • provisioning and managing cloud infrastructure
  • automating deployments and container orchestration
  • monitoring uptime and performance metrics
  • managing storage buckets and databases
  • setting up auto-scaling and load balancing

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. AWS Network Firewall is free to use, making it a low-risk choice to experiment with.
