S7. Glossary
What this page helps you do
Translate common launch and hosting language into normal words.
Why it matters
People often know what they want to do before they know the official name for it. This glossary helps reduce that mismatch.
You should already have
- questions
Skip this page if
- you are comfortable with the terms in the guide
What to do
Use this page when a word in the guide feels fuzzy or too technical.
Domain
The web address people type in to reach your app, like example.com.
DNS
The settings that tell the internet which server or service your domain should point to.
Hosting
The place where your app runs after it leaves your laptop.
Managed hosting
A hosting service that handles more of the setup for you. This is usually the easier default.
VPS
Short for virtual private server. In plain English, it means you rent a basic server and are more responsible for setting it up yourself.
Reverse proxy
A tool that sits in front of your app and forwards web traffic to it. If you are new, think of it as a traffic manager for incoming requests.
SSL / HTTPS
The security layer that makes your site load with the padlock and https:// instead of plain http://.
Environment variables
Settings stored outside your code, such as API keys, database URLs, or feature flags.
Deploy
Put your app on a real server or hosting service so other people can use it.
Rollback
Go back to the last working version after a bad deploy.
Logs
Recorded messages from your app that help you understand what happened when something broke.
Error tracking
A tool that collects crashes and failures so you notice them faster.
Background job
Work your app does outside the main page request, like sending emails or processing uploads later.
Recommended default
If a term feels unfamiliar, do not power through it. Check the term here, then go back to the guide page.
Common mistakes
- assuming a fancy term means a complicated decision
- treating words like DNS and hosting as the same thing
- storing secrets directly in code because environment settings sound intimidating

Advanced notes
If you are writing a new page, try to define important terms in the page itself the first time they appear instead of assuming the reader already saw this glossary.
