A VPS (virtual private server) is your own virtual computer inside a bigger shared machine. You get more control than on shared hosting, and more to manage. You get more freedom than on shared hosting, and with it more work.
What is a VPS?
A single physical machine is divided into several virtual servers, and each behaves like a separate computer with its own operating system, memory and settings. You or your provider manage the software.
The provider runs powerful hardware and uses virtualization to cut it into isolated parts. Your part has a guaranteed share of memory and processing power and its own Linux distributionA Linux distribution, such as Debian or Ubuntu, is a ready-made package of the operating system many servers run. It often decides which PHP version you get. or another operating system. Other customers on the same hardware cannot see your files.
There are two main flavors. On an unmanaged VPS the provider delivers an empty server and you do everything else. On a managed VPS the provider or a partner installs, updates and monitors the software for you. The hardware and the virtualization are the same; what differs is who does the maintenance.
What a VPS means for a PHP or WordPress site
On a VPS you choose the web serverA web server is the program, such as Apache, Nginx or LiteSpeed, that answers when a visitor opens your site and sends back the page and files., the PHP versionA PHP version is a numbered edition of PHP, like 8.3. Each edition is looked after for a limited time, then gets security fixes only, then nothing. and its settings, and you can install extra software. That suits sites with specific needs, such as several 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. versions side by side, a particular extension or heavier traffic.
The cost of that freedom is responsibility. Nobody patches the system unless you arrange it. The operating system, the web server, PHP, the database and every package need regular updates. When a security release such as the PHP update of 21 October 2026 comes out, it is your job, or your partner’s, to install it. A VPS that is set up once and then left alone will fall behind, and older PHP versions stop receiving fixes from the PHP project.
A good setup also includes a firewall, restricted logins, monitoring and backupsA backup is a separate copy of your website's files and database, so you can bring the site back after a mistake, a hack or a failed update. that are stored away from the server itself.
Resources are another point. A VPS has a fixed amount of memory and processing power, so a busy period can push it to its limit. Some providers let you upgrade the plan in a few steps, while others require a new server and a move. Ask which of the two applies before you rely on it.
What to ask before choosing a VPS
Who updates the operating system and PHP, and how often? Who is called when the server stops responding at night? Where are the backups stored, and has anyone tried to restore one? Is there 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. to test changes?
If the honest answer to most of these is “nobody”, a managed plan or a different type of web 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. is the safer choice.
When to act
Look at your VPS when it has not been updated for months, when you do not know which PHP version it runs or when the person who built it has left. Our PHP migration service can move a site from an old server to a cleaner setup, with a test before the switch and a clear way back.
Frequently asked questions
What is the difference between a VPS and shared hosting?
On shared hosting many sites share one server and the provider sets the software. On a VPS you get a virtual server of your own with its own settings, which gives you more control and more to maintain.
Is a VPS more secure than shared hosting?
Not automatically. A VPS is separated from other customers, but nobody updates it unless someone is responsible for it. An unmanaged VPS with old software is less safe than a well-run shared plan.
Do I need technical skills to run a VPS?
For an unmanaged VPS, yes. You install and update the operating system, the web server and PHP yourself. A managed VPS shifts that work to the provider or to a partner, at a higher price.
