Vercel Mastery · Step 3 of 6
Custom Domains & Edge Network
Learn to take your app live with a real domain, automatic HTTPS, and a serverless backend — the way production sites actually ship.
What you’ll walk away with
- Connect a custom domain to your deployed app and get automatic HTTPS without manually managing certificates
- Explain how the edge network distributes your app globally by default and why that matters for users
- Write and deploy serverless backend logic using Vercel Functions
- Complete a hands-on production-ready deployment that combines a custom domain, edge delivery, and serverless functions
- Understand the pieces that separate a local prototype from a live, production-grade deployment
Questions people ask before they start
Do I need to already own a domain to take this course?
The lesson on Custom Domains and Automatic HTTPS walks through connecting a domain, but you don't need one in hand before starting — the concepts and setup steps apply whenever you're ready to attach one.
Is this course about frontend design or backend infrastructure?
It's focused on infrastructure: domains, HTTPS, the edge network, and serverless functions via Vercel Functions. It's about making an app you've already built ready for real users, not about designing the app itself.
What does 'edge network' actually mean in this context?
The Edge Network lesson explains why global deployment is the default on modern platforms like Vercel — your app runs closer to users worldwide instead of from a single server location, and this course shows you why that's the standard, not an add-on.
Will I actually deploy something, or is this just theory?
The final lesson, Hands-On: A Production-Ready Vercel Deployment, has you apply everything — custom domain, HTTPS, edge deployment, and Vercel Functions — to a real, live deployment.
Do I need backend experience to use Vercel Functions?
No specific backend background is assumed. The Vercel Functions lesson introduces serverless backend logic as part of this module, building on the deployment concepts already covered.
Is this course part of a larger series?
This course, Custom Domains & Edge Network, contains one module — Making It Production-Ready — covering domains, HTTPS, the edge network, and serverless functions as a complete step in production-readiness.
