Deployment
The process of making your application available to real users on the internet.
Deployment is the final step in the software development lifecycle: taking code that works on your local machine and making it run on servers that are accessible to anyone on the internet. A deployed application is "in production" — it is live and serving real users.
Modern deployment platforms like Vercel, Netlify, Railway, and Fly.io have dramatically simplified this process. For most web applications, deployment is a matter of connecting a GitHub repository and pushing code — the platform handles building, hosting, SSL certificates, and global distribution automatically.
Key concepts: environment variables (secrets that differ between local and production), CI/CD pipelines (automated testing and deployment on every push), domains, and monitoring (knowing when your app is down before users tell you).
