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 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.

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

Next step

Go back to the page you were reading, or jump to S4. Choose your path.

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.
