Railway Mastery · Step 4 of 6
Custom Domains, Scaling & Monitoring
Take your Railway app from 'it works on my machine' to a production-ready service with a real domain, HTTPS, and monitoring.
What you’ll walk away with
- Attach a custom domain to your deployed app and configure HTTPS correctly
- Decide when to scale vertically versus horizontally, and configure your Railway service accordingly
- Set up metrics, logs, and alerting so you know when something breaks before your users tell you
- Walk through a hands-on production-ready configuration exercise on Railway from start to finish
- Explain the tradeoffs between different scaling approaches for a real deployed service
- Identify what a production-ready setup actually needs beyond just having code that runs
Questions people ask before they start
Do I need to already have an app deployed on Railway to take this course?
Yes — this course assumes you have a working deployed service and focuses specifically on making it production-ready with domains, HTTPS, scaling, and monitoring. It's not an intro to deployment.
Will this teach me general DNS or networking theory?
No, the course is practical and Railway-specific. The 'Custom Domains and HTTPS' lesson covers what you need to attach and secure a domain on Railway, not a deep networking course.
What's the difference between the scaling lesson and the hands-on lesson?
'Scaling: Vertical and Horizontal' explains the concepts and when to use each approach, while the 'Hands-On: Production-Ready Configuration' lesson has you actually apply domains, scaling, and monitoring together on a real service.
Does this cover monitoring tools outside of Railway?
No — the 'Metrics, Logs, and Alerting' lesson focuses on what's available and configurable within Railway itself, not third-party observability platforms.
Is this course focused on security?
It touches on HTTPS as part of making your domain setup secure, but the core focus is production readiness: domains, scaling, and monitoring — not a full security audit course.
How long is this course?
It's one module — Making It Real — with four lessons covering custom domains, scaling, monitoring, and a final hands-on configuration exercise.
