What Is Hosting? Shared, VPS and Cloud

01How Does Web Hosting Work?

A website needs a computer to run: the machine that stores the files, answers incoming requests and sends the page to the visitor is called a server. Hosting companies run these servers in data centers with uninterrupted power, cooling and high-speed internet, and rent you a part of one or the whole machine.

A domain name and hosting are different services. The domain name is your address, and hosting is the house at that address; DNS records connect the two. We explained the logic of that connection in our what is DNS article.

02What Is Shared Hosting?

Shared hosting is the model in which the CPU, memory and disk of a single server are shared among hundreds of sites. Server maintenance, security updates and the control panel are the hosting company's responsibility; you simply upload your files.

It is a sensible starting point for small corporate sites, personal blogs and low-traffic brochure pages. Its limit is the noisy-neighbor effect: when another site on the same server consumes a lot of resources, your site can slow down too. If resource limits are exceeded, the site may be suspended temporarily.

03What Is a VPS?

A VPS (virtual private server) is a physical server divided into independent parts through virtualization. Each VPS has its own dedicated CPU, memory and disk quota, its own operating system and full administrator access. Another customer's load affects yours far less than on shared hosting.

You can install your own software and tune the server settings to fit your project. In return, management responsibility grows: security updates, firewall, backups and monitoring become your job or your technical team's. Managed VPS plans, where the hosting company takes on these tasks, are also available.

04Dedicated and Cloud Servers

Dedicated Server

An entire physical server is reserved for you alone. It offers the highest and most predictable performance and is preferred for heavy database workloads, large e-commerce sites and projects that need special hardware. Setup and hardware changes take longer than on a VPS, and the management workload is the highest of all.

Cloud Server

A cloud server runs on a pool of resources made up of many physical machines. You can scale resources up or down within minutes and add new servers when you need them; if a piece of hardware fails, the virtual server can be moved to another machine. For sites with seasonal traffic, that flexibility is a major advantage.

Cloud billing is often usage-based, so costs change as traffic, storage and data transfer grow. For the broader picture of the cloud, see our what is cloud computing article.

05Hosting Types Compared

The table below puts the four types side by side using the same criteria. The cost column is a relative ranking; actual prices vary by provider, amount of resources and contract term.

06Hosting Selection Checklist

When choosing hosting based only on disk space and price, problems usually surface on the first busy day. Ask every provider you get a quote from the questions below.

• Server location: if most of your visitors are in a single country, a nearby data center reduces latency; with distant servers, using a CDN can close the gap.
• Disk type: NVMe SSD disks deliver noticeably better speed for database and file operations than traditional disks.
• Backups: how often are they taken, how many days are they kept, and how do you request a restore? Take your own independent backup too; you can find methods in our how to back up your website guide.
• SSL certificate: is a free certificate installed and renewed automatically?
• Software versions: can you choose your PHP, Node.js or database versions?
• Support: through which channels, during which hours and how quickly does technical support respond?
• Uptime guarantee: does the contract state an uptime commitment and what happens if it is missed?
• Ease of exit: when moving to another provider, can you easily take your files and database with you?

07How Does Hosting Affect Site Speed?

Server response time determines how long the first byte of the page takes to arrive (TTFB), and this is reflected directly in Core Web Vitals metrics such as LCP. Google's web.dev guidance recommends a TTFB of 0.8 seconds or less in general, and an LCP that does not exceed 2.5 seconds, for a good experience.

However, a fast server cannot make up for heavy images and unnecessary scripts. Real improvement comes from handling the server, cache, CDN and page code together. We apply this holistic approach in our speed and performance optimization service.

08What Determines Hosting Cost?

Hosting prices vary widely even within the same type. When comparing quotes, look not only at the monthly price but at what it covers; a package that looks cheap can end up costing more with paid backups or support.

On long-term contracts the first year may be discounted while the renewal price is different. When you request a quote, ask in writing for the renewal terms and how plan upgrades are charged.

• The amount of allocated CPU, memory and disk, and the disk type.
• Management service: whether you or the provider manages the server.
• Backup frequency, retention period and disaster recovery options.
• Data transfer and bandwidth limits; usage-based pricing in the cloud.
• Extras such as an additional IP address, a licensed control panel or an operating system license.
• Contract term and support level.

09Which Hosting for Which Project?

For a brochure site of a few pages or a corporate website, quality shared hosting or a small managed VPS is often enough. What matters most is the provider's backup and support quality.

For an online store, a booking system or applications that process data constantly, a VPS with reserved resources or a cloud server is a better fit. For an e-commerce site whose traffic multiplies during campaigns, or for hotel software that peaks in season, being able to scale resources quickly is decisive.
