What Is Hosting? What It’s Used For and the Types Available

Hosting, also called web hosting, is a service that stores a website’s files, images, databases, and other content on a server that is permanently connected to the Internet.

In simple terms: if the domain is your site’s address, hosting is where its content lives.

When someone types your domain into their browser, the hosting server receives the request and delivers the files needed to display the page.

That’s why you need two essential elements to publish a website: a domain, which identifies the site’s address, and a hosting service, which stores and serves its content.

What is hosting used for?

Hosting makes a website available on the Internet.

When you sign up for a hosting service, you get space and resources on a server to store your site’s files, databases, emails, and other components needed to run it.

Without hosting, your website’s files could exist on your computer, but no one would be able to access them over the Internet.

A good hosting service also provides resources related to performance, security, backups, management, and technical support.

Physical servers located in the data center. This is where website files are hosted and delivered (“served”) to users (visitors to a site) through the hosting service.

How does hosting work?

When someone visits a website, their browser connects to the server where it is hosted and requests the files needed to display the page.

The server processes the request and delivers HTML, images, stylesheets, scripts, and data to the visitor’s device.

This all usually happens in a fraction of a second. That’s why server speed, connectivity, storage, and hosting configuration directly affect a website’s performance.

Professional servers operate in data centers equipped with redundant connectivity, backup power, cooling, and physical and digital security measures.

Racks packed with web servers, always kept in cooled, fire-resistant environments.

Web hosting is a service offered by specialized companies that provide server space to store and publish websites on the Internet. These servers—high-performance computers located in data centers—operate in controlled environments with constant cooling, stabilized power, and strict physical security measures.

In addition to the physical environment, these centers have permanent Internet connectivity through high-speed redundant links, making hosted websites accessible from anywhere in the world, 24 hours a day, 365 days a year.
This combination of resources—infrastructure, connectivity, and environmental controls—is what ensures the stability, speed, and continuous availability of hosted websites.

What is the hardware behind a hosting service like?

Server hardware plays a fundamental role in hosting speed and stability. Components such as the CPU determine how many simultaneous visits a site can handle without its performance degrading. For example, our servers use high-end processors such as AMD EPYC and Intel Xeon Gold, specifically designed for demanding web workloads.

What is the difference between a domain and hosting?

Domains and hosting serve different purposes, but work together.

The domain is the address someone types to access a site, for example, duplika.com.

Hosting is the service that stores a site’s files and data and delivers them when someone visits that address.

You can think of it this way: the domain is a house’s address, and hosting is the house and the space where you keep all its contents.

You can register a domain with one company and sign up for hosting with another; the two are connected through DNS configuration.

What happens when we type a web address

When you type a web address into your browser’s address bar—for example, duplika.com—you are entering a URL (short for Uniform Resource Locator, the unique identifier used to locate a site on the Internet).

That URL acts like a digital set of coordinates: it tells the browser which server to connect to in order to retrieve the requested content. Your device—whether a computer, phone, or smart TV—then sends a request to the web server where the site is hosted, and the server responds by sending the files needed to display the page on your screen: text, images, stylesheets, scripts for special features, and so on.

This exchange happens in milliseconds. As the files download, the browser starts rendering—putting all the elements together and arranging them correctly on the screen—which results in the page loading and being compiled progressively. If the server is efficient and the site is well optimized, all the content can appear in less than two seconds.

Behind that web address and its fast loading is an invisible but crucial infrastructure: the hosting service. Every online project has specific needs—a store with thousands of visits is not the same as a personal blog—which is why there is no one-size-fits-all solution.

A professional and transparent hosting company should help you choose a plan that suits your site’s technical profile: its actual resource requirements, hardware suited to its traffic volume, keeping software up to date, and other key factors that improve the browsing experience for your website’s users.

And, besides the service itself, it’s also important to have tools that make day-to-day site management easier.

That’s why, to make things easier for customers, Duplika includes powerful cPanel with all its hosting plans. This management tool gives customers full control over their website, email accounts, backups, and many other essential features, helping them manage their hosting quickly, easily, and efficiently.

Web space in your hosting plan

We mentioned that hosting involves disk space as a sine qua non feature. This is no coincidence: hosting literally means “accommodation,” or the physical place where your website’s files are stored.

This storage space can be based on two main technologies: HDDs (with mechanically spinning platters) and modern SSDs (solid-state drives). How are they different, and why does this matter for speed?

What is the difference between HDD, SSD, and NVMe hosting?

Servers can use different storage technologies.

HDD uses mechanical disks and is the traditional technology. It offers high capacity at a low cost, but has longer access times.

SSD uses solid-state memory with no moving parts, allowing files to be accessed much faster.

NVMe is a solid-state storage technology designed to take advantage of faster connections and further reduce latency.

For a modern website, SSD or NVMe offers a clear advantage in speed and responsiveness over a traditional HDD.

The evolution of data storage

To understand it, imagine a vinyl record: the turntable spins, the stylus reads the grooves sequentially, and this plays the music. This mechanism is essentially similar to how an HDD works: physical platters spin at high speed while a head moves to read (or write) data.

By contrast, an SSD has no moving parts. It’s more like an ultrafast USB flash drive: it accesses data directly on memory chips, making it much faster, quieter, and more resistant to wear than a traditional HDD.

In the context of hosting, this means faster-loading sites, shorter response times, and a better experience for visitors. That’s why at Duplika, we use SSDs exclusively in all our plans.

HDD hosting is still a deeply entrenched system because it came before SSD and is much more affordable. But each generation of SSD far outperforms the previous one, so the gap between the two technologies is barely comparable.

You can immediately identify a mechanical HDD in a desktop computer because it makes noise when reading or writing data: a faint mechanical rumble, as if tiny grains of rice were bumping into each other. An SSD is silent.

HDD hosting uses the traditional storage system. Its main advantage is still its low cost, making it an affordable option for those who prioritize budget over performance. Although modern versions have improved rotational speeds to boost performance, HDD technology faces an insurmountable physical limitation: because it relies on moving mechanical parts—such as motors and read/write heads—it cannot compete with current SSD systems in speed or durability.

The relatively new SSD hosting is like night and day compared with HDD hosting: it uses “solid-state” drives, circuit boards with no motors or spinning disks. With SSDs, there are no moving parts; everything works like a large electronic memory. This means they make no noise, benefit from a longer lifespan, and—no small thing—can access multiple files at the same time, just like RAM.

For practical purposes, the difference between HDD and SSD is comparable to this:

→ With an HDD, to eat a sandwich, you have to get up from the couch and walk to the kitchen, open the fridge, and find the ingredients one at a time.
→ With an SSD, we fly to the fridge in a second, grab all the ingredients at the same time, and have a sandwich ready in 10% of the time it took in the previous example.
That’s how different these two technologies are.

Of course, this technological leap comes at a price. On average, storing the same amount of information on an SSD costs twice as much as on an HDD per megabyte of space.
That’s why most hosting providers still don’t offer solid-state drives in their plans. At Duplika, on the other hand, we use SSDs exclusively across all our services.

Types of Hosting

There are different types of hosting services, so the best choice depends on your project’s features and needs.

Shared hosting

This is the most common and affordable type of hosting. Several websites share the same physical server and resources such as CPU, memory, and bandwidth. If the server is well configured and the site is well optimized, it’s an excellent option for getting a project started.

In these environments, it’s essential for the provider to use technologies such as CloudLinux (as we do). CloudLinux isolates each account to prevent an account issue—including infections—from affecting other sites on the server.

Multi-account / Reseller plans

Reseller hosting plans let you create and manage multiple independent hosting accounts from a single platform. They’re especially useful for agencies, developers, and professionals who manage sites for different clients.

VPS and Cloud servers

A VPS server uses virtualization, usually KVM or VMWare, to allocate independent resources and configurations within a server infrastructure. It offers more control, scalability, and capacity than a shared hosting plan.

Dedicated servers

Unlike cloud hosting, here the entire physical server is reserved exclusively for the customer, with no virtualization layer. It’s the most powerful and customizable option, designed for large-scale projects or those with very specific technical needs.

What is “WordPress Hosting”?

WordPress hosting emerged to support the tremendous popularity of this content management system, which powers no less than 43.4% of all websites worldwide (according to W3Techs). WordPress is software for creating and managing sites, and like any software, it needs suitable hardware and technical configurations.

In this context, WordPress hosting is a hosting service specifically optimized for sites built with WordPress. This means having sufficient memory, processing capacity, and connectivity, along with a software platform configured to help the site run with maximum speed, security, and responsiveness.

What should you consider when choosing a hosting service?

Before signing up for hosting, pay particular attention to:

Performance: storage type, CPU, memory, and server technology.

Availability: look for a provider that clearly states its uptime commitment.

Technical support: make sure you can contact people who can help when a real problem arises.

Backups: check how they’re created and how long they’re kept.

Security: firewall, account isolation, malware protection, and updates.

Scalability: you should be able to increase resources or change plans without having to rebuild the entire site.

Transparency: check the limits, renewal price, and included resources before signing up.
