Network Security — VPCs, Firewalls, Zero Trust
Network boundaries, security groups, and zero trust architecture for modern applications
When you deploy an application to Vercel or Netlify, the network security is handled for you. Your code runs on their infrastructure, behind their firewalls, on their network. But the moment you add a database, a Redis cache, a background job processor, or any backend service — you're building a network. And that network needs to be secured.
Network security isn't just for DevOps engineers at Fortune 500 companies. If you're running a database on Supabase, a Redis instance on Upstash, or a server on Railway, you're making network security decisions whether you realize it or not. This lesson helps you make them intentionally.
