Web hosting is a service that stores your website's files (HTML, images, databases, everything) on a server that's connected to the internet around the clock. When someone types your domain into a browser, their computer requests those files from your host's server, and the server sends them back. No hosting, no website: your domain name alone points to nothing until it's connected to a server that actually holds your files.
Every website needs this, whether it's a five-page brochure site or a full WordPress store. The differences between hosting providers come down to speed, reliability, security, and how much of the technical work they handle for you.
The three pieces: domain, DNS, and server
These three things work together, but they're not the same thing:
- Domain name: the address people type, like
yoursite.com. You register this separately (or bundle it with hosting). - DNS: the system that translates your domain into the numeric IP address of the server storing your files. Nameservers are where this translation is configured.
- Server: the actual machine (or virtual machine) where your files, database, and email live, and that answers requests from visitors' browsers.
When you buy hosting, you get space on a server. When you point your domain's nameservers at that host, DNS starts routing visitors to the right place. This handshake is why a freshly registered domain or a freshly moved site can take a little time to start working everywhere: DNS changes need to propagate.
Shared, VPS, and dedicated: what actually changes
Most hosting comes in a few tiers, and the difference is how much of the server's resources are yours alone:
- Shared hosting: many websites live on one server, splitting its CPU and memory. It's the cheapest option and it's plenty for most small business sites, blogs, and portfolios. The tradeoff is that you share resources with other accounts on the same box.
- VPS (virtual private server): the physical server is divided into isolated virtual machines, so your slice of CPU and memory is guaranteed and not affected by other tenants' traffic spikes.
- Dedicated server: an entire physical machine is yours. This is for sites with heavy, consistent traffic or specific compliance and performance needs.
For a typical WordPress site, blog, or small store, shared hosting on a fast stack is usually the right starting point, and you can upgrade later without rebuilding anything.
What a good host actually does for you
Beyond just storing files, a real hosting provider handles the infrastructure work that would otherwise be your job: keeping the server patched and secure, issuing and renewing SSL certificates so your site loads over HTTPS, running backups, configuring email for your domain, and giving you a control panel (like cPanel) to manage databases, files, and domains without touching a command line.
If you're moving from another host, look for one that offers to move your existing site for you, on most hosting accounts that's a standard part of switching, rather than leaving you to export and re-upload everything by hand.
Once you're hosted: keeping the site itself healthy
Hosting is the foundation, but a live site also needs upkeep: content, security hygiene, and performance. If your plan includes a tool for writing blog content, a simple weekly content routine is a good way to keep a blog active without it becoming a chore, and finding keywords to write about helps you pick topics people are actually searching for. On the security side, once you have email running on your domain, it's worth understanding the difference between spam filtering and challenge-response tools; see fighting inbound spam for why one approach works better than the other.
When to contact support
If your domain isn't resolving to your new host, your SSL certificate isn't issuing, or you're not sure whether your current plan fits your traffic, open a ticket through the portal. Support is real people, available via ticket or live chat, and they can look at your specific account rather than general troubleshooting steps.
