Deployment

A deployment is the step that puts a new version of your website live for visitors, ideally automated, tested and easy to undo. It is the moment where work stops being a draft and becomes what your visitors see. A good deployment is boring: the same steps every time, with a check at the end and a way back if something looks off.

What is a deployment?

Every site change travels from an editor or developer to the public server. A deployment is the controlled way to make that trip. It usually has stages: collect the new version, run checks, copy it to the server, switch visitors over to it and confirm it works.

On many older PHPPHP is a programming language that builds your web pages on the computer that hosts your site, just before they reach the visitor. WordPress runs on it. sites, this is done by uploading files over FTP or editing them on the server. That works, but it leaves no record of what changed, no automatic test and no easy way to undo a mistake. A modern setup keeps the code in version control, tests it, and publishes it with a script or a hostingWeb hosting is the service that keeps your website's files on a computer that is always online, so visitors can open your site at any time. service, so the same process runs every time.

What deployment means for a PHP or WordPress site

For a classic PHP or WordPressWordPress is free software for building and editing a website in your browser.

The content and many settings live in the database and change on the live site as editors work. If you deploy files over a database that has moved on, or the reverse, you can break things in ways that are hard to see.

That is why it is smart to test a change on a staging environmentA staging environment is a private copy of your website where you try updates first, so any mistakes happen there and not on the live site. before it goes live, and to have a rollbackA rollback means going back to the last version of your website that worked, after an update has gone wrong. plan. A deployment without a way back is a gamble.

The site is built into a set of finished files, and the deployment is replacing the old set with the new set. There is no database to migrate and no PHP to run when a page is viewed. Many hosts let you keep earlier builds, so going back can be as simple as selecting the previous one.

What a good deployment looks like

Check for four things. The change is tested before it goes live. The process is repeatable, so any team member gets the same result. There is a record of what was released and when. And there is a fast way back.

For your own site, ask your developer or agency a simple question: if the update we release today fails, how long does it take to return to yesterday’s version, and have you tried it?

When to act

Rethink your deployment process if changes go live by hand with no test, if nobody can say what was changed last week, or if the last failed update took hours to undo. These are common signs of a site that has grown without a process. If you want to remove the moving parts altogether, a WordPress to static site move turns your site into static files that deploy in one step, and our PHP migration service moves a site to a new setup with a test first.
