Hosting

Hosting, or web hosting, is a service in which a provider stores all the files that make up a website, such as code, images, and content, on a server and makes that website accessible to visitors over the internet.

Every website needs somewhere to physically reside, and hosting providers supply and maintain the servers that fill that role, along with related infrastructure such as scalable storage, bandwidth, security protections, and backups.

Many hosting providers also offer domain registration and DNS configuration alongside hosting itself, allowing a business to manage both its server space and its web address through a single provider, though these remain conceptually separate services: a domain name is the address visitors type in, while hosting is where the actual site files live.

How it works

When a visitor types a website’s domain name into their browser, a short sequence of steps takes place before the page appears on screen.

DNS lookup: the browser queries the Domain Name System, often described as the internet’s phonebook, to translate the human-readable domain name into the numeric IP address of the server where the site is hosted.

Server request: the browser sends a request to that server asking for the specific page or resource needed.

File retrieval: the hosting server locates the relevant files, whether static HTML or content generated dynamically by a CMS, and prepares them for delivery.

Page delivery: the server sends the requested files back to the visitor’s browser, which then renders them into the visible page. This entire exchange typically takes well under a second on a well-configured hosting setup, though server quality, location, and current load can all affect that speed.

Example

A small business launching its first online store signs up for a shared hosting plan, the most affordable option, since the site expects only a few hundred visitors a day. As the store grows and starts processing hundreds of orders daily, page load times begin to slow during busy periods because the server’s resources are shared with many other websites. The owner upgrades to a VPS hosting plan, which guarantees a fixed share of server resources, resolving the slowdown without the higher cost of renting an entire dedicated server.

Key characteristics

• Shared hosting: Multiple websites run on the same physical server and share its resources, making this the most affordable option but also the most vulnerable to slowdowns caused by other sites on the same server.
• VPS hosting: A physical server is partitioned into separate virtual sections, each with guaranteed resources, offering a middle ground between the affordability of shared hosting and the performance of a dedicated server.
• Dedicated hosting: An entire physical server is reserved for a single website or business, offering maximum performance and control at a significantly higher cost, typically suited to large, high-traffic operations.
• Cloud hosting: Resources are drawn from a network of interconnected servers rather than a single machine, offering strong reliability and the ability to scale resources up or down as traffic fluctuates.
• Managed vs unmanaged options: Managed hosting plans have the provider handle server maintenance, updates, and security, while unmanaged plans leave those responsibilities to the website owner, typically at a lower cost.

Related terms

• Domain name – the web address that visitors use to reach a hosted website, conceptually separate from the hosting service itself.
• Extension – the suffix portion of a domain name, such as .com or .shop, registered alongside or separately from a hosting plan.
• CMS – software that manages a website’s content, running on top of a hosting server to generate the pages visitors see.
• Ecommerce – the broader category of online commercial activity that depends on reliable hosting to remain accessible to customers.
• WooCommerce – a self-hosted ecommerce plugin that requires the user to source and maintain their own hosting, unlike fully hosted platforms.

Frequently asked questions

What is the difference between shared and VPS hosting?

Shared hosting places multiple websites on the same server with no guaranteed share of resources, making it the most affordable but also the most vulnerable to slowdowns from other sites. VPS hosting partitions a server into separate virtual sections, each with guaranteed resources, offering better performance and security at a higher cost.

How is hosting different from a domain name?

A domain name is the web address visitors type into their browser to reach a website, while hosting is the service that stores the actual files making up that website on a server. Many providers offer both together, but they remain functionally separate services.

Do I need to manage my own server with hosting?

This depends on whether a hosting plan is managed or unmanaged. Managed hosting plans have the provider handle server maintenance, security updates, and backups, while unmanaged plans leave those responsibilities to the website owner, typically in exchange for a lower price.

When should a business upgrade from shared to a more advanced hosting plan?

Common signs include slower page load times during busy periods, frequent timeouts during traffic spikes, or a need for specific server software or configurations that shared hosting does not support. Businesses processing a high volume of transactions or sensitive customer data, such as growing ecommerce stores, often outgrow shared hosting first.
