Deployment
DevOps & AdminDeployment is the process of delivering a website or application from development into a live hosting environment so users can access it. It typically includes building code, transferring files, applying configuration, running database migrations, and restarting services. Deployments can be manual or automated through CI/CD pipelines, and they aim to reduce downtime, errors, and inconsistencies between environments.
How It Works
A deployment starts when a specific version of your code is selected for release, often from a Git branch or tag. The code may be built (for example, compiling assets or packaging a release), then delivered to the server via methods such as SSH/SFTP, rsync, Git-based pulls, or container image pulls. Configuration is applied through environment variables and config files, and the web stack (Nginx or Apache, PHP-FPM, Node.js, etc.) is reloaded or restarted to serve the new version.
Modern deployments are frequently automated using CI/CD. A pipeline runs tests, builds artifacts, and promotes them through environments (development, staging, production). To reduce risk, teams use strategies like rolling deployments, blue-green deployments, or canary releases, plus health checks and automatic rollback. For dynamic sites, deployments may also run database migrations, clear caches, and warm up application caches to avoid performance drops after release.
Why It Matters for Web Hosting
Deployment affects how quickly and safely you can update a site, which is central to choosing a hosting plan. When comparing hosting options, look for SSH access, Git support, staging environments, cron jobs, build tooling compatibility, and permissions to restart services or run migrations. Also consider whether the platform supports zero-downtime patterns, backups for rollback, and predictable resource limits that will not break builds or deployments under load.
Common Use Cases
- Publishing new website content and theme changes (for example, WordPress code updates)
- Releasing application features and bug fixes with a CI/CD pipeline
- Deploying containerized services using Docker images and orchestration tools
- Applying database schema changes and running migrations during a release
- Rolling back to a previous release after an error or failed health check
Deployment vs Release
Deployment is the act of putting a new version into an environment (such as production), while a release is making that version available to users. You can deploy without releasing by using feature flags, staged rollouts, or internal-only access, and you can treat a release as a business decision layered on top of the technical deployment. In hosting terms, deployment is about server access and automation capabilities; release is about traffic exposure and change management.
