Web hosting supplies the computing environment that makes a website available to visitors. It stores and serves files and, when needed, runs application code and databases. A domain name helps people find that environment; buying a domain alone does not publish a working website.
Follow one page request
Suppose you open a small business website. DNS helps your browser find an address for the requested hostname. The browser connects and requests a resource over HTTP, normally protected by HTTPS. A server returns a response; the browser interprets the page and may request images, stylesheets and scripts separately. A dynamic application may also query a database before responding.
Some responses come from a cache or content delivery network rather than directly from the original hosting environment. A page loading successfully therefore does not necessarily mean that every application dependency is healthy. See MDN’s explanation of clients, servers, DNS and HTTP for the underlying request model.
Keep the services separate
- Domain registration: the right to use a name for the registration period.
- DNS: records that direct names to services.
- Hosting: the environment serving the website or application.
- Website software: the files, content and application you publish.
- Email: a separate service that may or may not be included in the hosting package.
One company can supply several of these services, but they remain different responsibilities. Keep access to the domain and DNS accounts even if someone else builds the website.
What you rent changes the work you must do
A shared account normally provides a provider-configured environment used by multiple customers. A VPS provides a virtual environment on underlying hardware; its CPU allocation and management scope depend on the service. A dedicated server reserves a machine for one customer, who can run multiple websites or applications on it.
The word “cloud” does not, by itself, prove that your application has replicas or automatic failover. Confirm the actual architecture. Likewise, administrator access and dedicated hardware do not automatically supply patching, backups or recovery.
Use the infrastructure comparison when you are ready to compare these operating models. There is no need to choose a larger category merely because it sounds more powerful.
Check what the hosting agreement includes
Record the application requirements, storage needs and expected usage. Check supported runtimes, database access, account limits, recurring charges and the boundary of technical support. Ask who maintains the application and who can restore it if an update or deletion goes wrong.
HTTPS protects the connection; it does not make insecure application code safe. A server holding your files is not a backup of those files. Confirm backup retention and restoration responsibilities separately, and test the recovery path before relying on it.
Before you publish
Connect the intended domain, deploy a test version, check HTTPS and verify important actions such as login, forms and order confirmation. Confirm that email still works if you change DNS. Keep a recoverable copy of the site and document who controls each account.
